In a switch spoofing attack, an attacking host imitates a trunking switch by speaking the tagging and trunking protocols (e.g. Multiple VLAN Registration Protocol, IEEE 802.1Q, Dynamic Trunking Protocol) used in maintaining a VLAN. Traffic for multiple VLANs is then accessible to the attacking host.

The Dynamic Trunking Protocol (DTP) is a proprietary networking protocol developed by Cisco Systems for the purpose of negotiating trunking on a link between two VLAN-aware switches, and for negotiating the type of trunking encapsulation to be used. It works on Layer 2 of the OSI model. VLAN trunks formed using DTP may utilize either IEEE 802.1Q or Cisco ISL trunking protocols. DTP should not be confused with VTP, as they serve different purposes.

The term trunking is used in the United Kingdom for electrical wireways, generally rectangular in cross section with removable lids. Mini trunking is a term used in the UK for small form-factor (usually 6 mm to 25 mm square or rectangle sectioned) PVC wireways. In India, this trunking is available with self-fixing tape to ease off installation. In some countries including Iran, the term 'Trunking' is a channel that enable us to install some modules on it such as switches and sockets.

Trunking also refers to the connection of switches and circuits within a telephone exchange. Trunking is closely related to the concept of grading. Trunking allows a group of inlet switches at the same time. Thus the service provider can provide a lesser number of circuits than might otherwise be required, allowing many users to "share" a smaller number of connections and achieve capacity savings.

In telecommunications, trunking is a way to provide network access to many clients by sharing a set of lines or frequencies instead of providing them individually. This is analogous to the structure of a tree with one trunk and many branches. Examples of this include telephone systems and the two-way radios commonly used by police agencies. Trunking, in the form of link aggregation and VLAN tagging, has been applied in computer networking as well.

The TETRA trunked radio standard was developed by the European Telecommunications Standards Institute (ETSI), as a digital alternative to analogue trunked systems. However, TETRA, with its enhanced encryption capability, has developed into a higher tier (public safety) product, currently mainly used by governments, some larger airports and government-owned utilities. DMR (digital mobile radio), and dPMR (digital private mobile radio) are more recent ETSI-standards for digital mobile radio using two-slot TDMA and FDMA respectively. The Tier 3 standard for these systems defines a trunking protocol very similar to MPT1327 and is intended as a potential migration path for existing and perhaps future trunking customers.

There are some very basic restrictions in the event Site Trunking (a site loses its link to the Zone Controller) does occur but for all intents and purposes once an IR site is in Site Trunking mode it's a free-for-all site. IR sites are generally used for a small geographic area or to fill in holes. For sites that are used to fill in coverage traffic is very limited. To allow as limited a number of channels for use, and to be spectrum efficient, Voice On Control (VOC) was developed to permit the control channel to temporarily act as a voice channel.

To improve spectrum use, P25 Phase 2 was developed for trunking systems using a 2-slot TDMA scheme and is now required for all new trunking systems in the 700 MHz band. Phase 2 uses the AMBE+2 voice codec to reduce the needed bitrate so that one voice channel will only require 6,000 bits per second (including error correction and signalling). Phase 2 is not backwards compatible with Phase 1 (due to the TDMA operation), although multi-mode TDMA radios and systems are capable of operating in Phase 1 mode when required, if enabled. A subscriber radio cannot use TDMA transmission without a synchronization source; therefore direct radio to radio communication resorts to conventional FDMA digital operation.

The T-carrier is a hardware specification for carrying multiple time-division multiplexed (TDM) telecommunications channels over a single four-wire transmission circuit. It was developed by AT&T; at Bell Laboratories ca. 1957 and first employed by 1962 for long-haul pulse-code modulation (PCM) digital voice transmission with the D1 channel bank. The T-carriers are commonly used for trunking between switching centers in a telephone network, including to private branch exchange (PBX) interconnect points.

It can serve as a gateway between IP phones and the PSTN via T- or E-carrier interfaces or analog FXO cards. The Inter-Asterisk eXchange (IAX) protocol, RFC 5456, native to Asterisk, provides efficient trunking of calls between Asterisk PBX systems, in addition to distributing some configuration logic. Many VoIP service providers support it for call completion into the PSTN, often because they themselves have deployed Asterisk or offer it as a hosted application. Some telephones also support the IAX protocol.

Heavy seas made visual communication almost impossible, and Jason was damaged by the weather and forced to carry out repairs to the ventilation trunking. By the afternoon, only 22 ships were left in the convoy, the others having retreated. Over the next few days, more destroyers and corvettes joined the escort but and left for Seydisfjord, Iceland to refuel. The weather started to clear on 23 February, but German aircraft sighted the convoy and one day later it was attacked by and .

The Parton to Lillyhall bypass was opened in December 2008 after a period of 18 months construction. The road runs from the junction with the A596 at Lillyhall to a new junction created close to the A595 junction for Lowca. The new road replaces a winding, narrow section of the A595 which passed through the village of Distington. Prior to this project the A595 was considered for de-trunking, meaning the scheme would have become the responsibility of Cumbria County Council.

Example without and with VTP On Cisco Devices, VTP (VLAN Trunking Protocol) maintains VLAN configuration consistency across a single Layer 2 network. VTP uses Layer 2 frames to manage the addition, deletion, and renaming of VLANs from switches in the VTP client mode. VTP is responsible for synchronizing VLAN information within a VTP domain and reduces the need to configure the same VLAN information on each switch thereby minimizing the possibility of configuration inconsistencies that arise when changes are made.

The new seating was controversial - it was almost identical to that of the Class 314, albeit with a 2+2 configuration. This allowed for many more standing passengers, but with far fewer seats than previously. The original seating was deep sprung and (arguably) far more comfortable. In addition, the original heating, which was provided by panelled in heaters beneath the seats, was replaced by heaters in longitudinal trunking along the lower bodyside, with the spaces under the new seats opened up.

The traditional telephone networks are based on the principle of point-to-point communications, for example, an office building sends and receives phone calls over an ISDN line to the telephone exchange. Early Voice over IP deployments have copied this model, sending phone calls over SIP Trunking (a virtual equivalent of ISDN) to an Internet telephony service provider (ITSP) (a virtual telephone exchange). Such paradigms have striven to emulate many of the aspects of traditional telephony, such as the telephone number.

In the context of Ethernet VLANs, Avaya and Cisco use the term ' to mean carrying multiple VLANs through a single network link through the use of a trunking protocol. To allow for multiple VLANs on one link, frames from individual VLANs must be identified. The most common and preferred method, IEEE 802.1Q adds a tag to the Ethernet frame, labeling it as belonging to a certain VLAN. Since 802.1Q is an open standard, it is the only option in an environment with multiple-vendor equipment.

Commandant Teste had a very large hangar amidships that was three decks high and measured approximately . It was partitioned in two by a bulkhead that incorporated the exhaust uptakes for the funnel and the ventilation trunking for the machinery spaces. It could accommodate ten large torpedo bombers with folding wings; two smaller aircraft with folding wings could be stowed in lieu of each torpedo bomber. Two additional large aircraft and four smaller aircraft could be carried dismantled in crates in a hold below the hangar.

The K777 Team is a combination of engineers, boat racers, boat builders, gas turbine specialists and Members of Windermere Boat Racing Club. They built a controversial visual copy of Donald Campbell's Bluebird K7, though during its sole public appearance on Coniston Water in 2011 it failed to plane, partially sank, and ultimately collapsed its air intake trunking. A test on Loch Ken, in south-west Scotland, in October 2014 was also unsuccessful; although the boat did not sink, it was again unable to plane.

There is also nothing to prevent multiple groups in the same area from choosing the same channel, causing conflicts. A trunked radio system is an advanced alternative in which the channel selection process is done automatically. Trunking is a more automated and complex radio system, but provides the benefits of less user intervention to operate the radio and greater spectral efficiency with large numbers of users. Instead of assigning a radio channel to one particular user group at a time, users are instead assigned to a logical grouping, a "talkgroup".

|
The exhaust and intake trunking was also utilised to allow the removal of complete engines, giving a rapid 24-hour exchange time. Exmouth rejoined the fleet on 5 June 1968, and during the 1970s she carried out extended trials to validate the feasibility of all-gas turbine propulsion. The foresight of her conversion was illustrated when after only 64 hours of running, an entire ring of Olympus turbine blades failed. Her test cruises took her to the Mediterranean Sea, where she took part in various trials and exercises based at Malta.

With increasing awareness of the importance of government’s ability to deal with critical situations, there is a growing demand for emergency response systems in China. Without an organization like the National Emergency Number Association (NENA) in the United States, China has not yet developed a national technical standard for its emergency response system. Large and economically well-off cities in China like Beijing, Tianjin, Nanning and Chengdu have started building public safety networks by introducing TETRA-based digital trunking system that integrate with their existing analogue systems. More Chinese cities followed in 2005.

Jordan & Caresse, pp. 288–289 The following year, she became a gunnery training ship at Toulon, but she suffered a serious boiler fire on 6 June 1923 that required repairs, so she was given the first of her modernisations between 9 July 1923 and 16 April 1924, at La Seyne-sur-Mer. This included replacing four boilers with oil-fired du Temple boilers and trunking together her two forward funnels. The maximum elevation of the main armament was increased from 12° to 23° which increased their maximum range to .

As a result of the magazine changes, and to keep the funnels distant from the bridge, only two funnels were required; the forward boiler room uptakes trunked up into a large fore-funnel. This was raked in York to clear the flue gases from the bridge, but was straight in Exeter owing to an altered bridge design and more extensive trunking. To maintain homogeneity of appearance, York stepped raked masts and Exeter vertical ones. York had a tall "platform" style bridge as seen in the Counties, which was somewhat distant from 'B' turret.

This may be a specialised bendable pipe, called a conduit, or one of several varieties of metal (rigid steel or aluminium) or non-metallic (PVC or HDPE) tubing. Rectangular cross-section metal or PVC wire troughs (North America) or trunking (UK) may be used if many circuits are required. Wires run underground may be run in plastic tubing encased in concrete, but metal elbows may be used in severe pulls. Wiring in exposed areas, for example factory floors, may be run in cable trays or rectangular raceways having lids.

In two-way radio communications, trunking refers to the ability of transmissions to be served by free channels whose availability is determined by algorithmic protocols. In conventional (i.e., not trunked) radio, users of a single service share one or more exclusive radio channels and must wait their turn to use them, analogous to the operation of a group of cashiers in a grocery store, where each cashier serves his/her own line of customers. The cashier represents each radio channel, and each customer represents a radio user transmitting on their radio.

Manned missions, beginning with Project Mercury in 1958, demanded a real-time voice circuit in addition to data circuits, and improved reliability. Specifications for the Mercury Network were issued on May 21, 1959, establishing a baseline with a mission control center in Cape Canaveral (later Houston), data convergence at Goddard, and switching stations overseas to provide redundancy and trunking over expensive transoceanic cables. These decisions would shape NASCOM for years to follow. The Mercury network was designed by the Tracking and Ground Instrumentation Unit (TAGIU) at Langley, with support from Goddard.

In the context of VLANs, the term trunk denotes a network link carrying multiple VLANs, which are identified by labels (or tags) inserted into their packets. Such trunks must run between tagged ports of VLAN-aware devices, so they are often switch-to-switch or switch-to-router links rather than links to hosts. (Note that the term 'trunk' is also used for what Cisco calls "channels" : Link Aggregation or Port Trunking). A router (Layer 3 device) serves as the backbone for network traffic going across different VLANs.

Versions of the Altay system are still in use today as a trunking system in some parts of Russia. In 1959 a private telephone company located in Brewster, Kansas, USA, the S&T; Telephone Company, (still in business today) with the use of Motorola radio telephone equipment and a private tower facility, offered to the public cellular telephone services in that local area of NW Kansas. In 1966, Bulgaria presented the pocket mobile automatic telephone RAT-0,5 combined with a base station RATZ-10 (RATC-10) on Interorgtechnika-66 international exhibition.

The hatch is sealed before ascent to retain internal pressure. At the surface, this type of bell can lock on to a hyperbaric chamber where the divers live under saturation or are decompressed. The bell is mated with the chamber system via the bottom hatchway or a side hatchway, and the trunking in between is pressurized to enable the divers to transfer through to the chamber under pressure. In saturation diving the bell is merely the ride to and from the job, and the chamber system is the living quarters.

A young designer, Jeff Childress, created an autonomous radio base-station controller, known as the GETC (General Electric Trunking Card). The GETC was a general-purpose controller with input/output optimized for radio system applications. Childress and the team demonstrated that a smart controller could be adapted to a variety of applications, but his interest was really in fault tolerance. The competition dealt with fault tolerance by means of the "brute force and ignorance" approach, deploying double the hardware for their controllers, and interconnecting them with massive and problematic relay banks .

An autopsy was conducted on Hoffman, which revealed no evidence of any disease to his heart or other organs; and no evidence of electrical shock to the body. He had a one-inch vertical laceration on his forehead, which was thought to have been caused after death. A lung dissection showed that he had died by drowning. When asked to theorize how this could happen, Dr. Hendry, the autopsy doctor, testified that, “This occurred because he fell head first, maskless and presumably unconscious, into the trunking of the diving bell.

When the craft rose out of the ground effect, the air formed itself into a single narrow column, described by Frost as "tree trunking". At intermediate altitudes the craft would momentarily transition from one regime to the other, during which time one side of the vehicle would be entirely supported while the support was disappearing under the other. This led to a strong pitching motion towards the unsupported side. As soon as this occurred that side would approach the ground and re-establish the supporting air, while the other side would then be raised above this limit.

In theory, all P25 compliant equipment is interoperable. In practice, interoperable communications isn't achievable without effective governance, standardized operating procedures, effective training and exercises, and inter- jurisdictional coordination. The difficulties inherent in developing P25 networks using features such as digital voice, encryption, or trunking sometimes result in feature-backlash and organizational retreat to minimal "feature-free" P25 implementations which fulfill the letter of any Project 25 migration requirement without realizing the benefits thereof. Additionally, while not a technical issue per se, frictions often result from the unwieldy bureaucratic inter-agency processes that tend to develop in order to coordinate interoperability decisions.

The term has been used in several other areas. Operational responsiveness has been used in a military context to describe both the ability of a military unit or operation to respond quickly and effectively to changes in the local situation as they occur, and the ability for the central leadership to quickly provide information, resources, or new capabilities to the field, typically in response to expressed needs of local commanders.Operationally Responsive Space Office, the US Air Force's Operationally Responsive Space Office.Joint multichannel trunking and switching system, an example of using operational responsiveness to talk about adapting to changing (and possibly degrading) conditions.

GARP was defined by the IEEE 802.1 working group to provide a generic framework allowing bridges (or other devices like switches) to register and de-register attribute values such as VLAN identifiers and multicast group membership. GARP defines the architecture, rules of operation, state machines and variables for the registration and de-registration of attribute values. GARP was used by two applications: GARP VLAN Registration Protocol (GVRP) for registering VLAN trunking between multilayer switches, and by the GARP Multicast Registration Protocol (GMRP). The latter two were both mostly enhancements for VLAN-aware switches per definition in IEEE 802.1Q.

German Leopard 2A4 with turret snorkel, 2010 Some military vehicles are capable of "wading" using waterproof screens to keep the upper hull dry. In World War II the tanks following the Sherman DDs were given waterproofed hulls and trunking was fixed to the engine intakes and exhausts to allow them to come ashore from landing craft in shallow water. The Germans gave their Tiger tank a long snorkel, essentially a long tube on the commander's hatch that allowed it to wade through four metres of water. The Leopard 2 tank can use a series of rings to create a long tube.

It was originally defined in IEEE 802.1s as an amendment to 802.1Q, 1998 edition and later merged into IEEE 802.1Q-2005 Standard, clearly defines an extension or an evolution of Radia Perlman's Spanning Tree Protocol (STP) and the Rapid Spanning Tree Protocol (RSTP). It has some similarities with Cisco Systems' Multiple Instances Spanning Tree Protocol (MISTP), but there are some differences. The original STP and RSTP work on the physical link level, preventing bridge loops when redundant paths are present. However, when a LAN is virtualized using VLAN trunking, each physical link represents multiple logical connections.

Since the radio would not transmit unless the ready light was lit, checking output power, frequency, or deviation on the bench or outside the system coverage area required the technician to attach a test box. The box bypassed the radio trunking logic so adjustments could be made in a conventional single-channel mode. Antenna forward and reflected power in a vehicle on a working system was typically checked by bringing up a talk channel and transmitting normally. Once a channel was brought up it could be 'held' for up to 3 minutes (the limit of the system carrier control timer).
|
|
The control channel computer sends packets of data to enable one talkgroup to talk together, regardless of frequency. The primary purpose of this type of system is efficiency; many people can carry many conversations over only a few distinct frequencies.Talk groups, scanning, and group calls are defined in, "Section 2: Needs Summary," Arizona Phase II Final Report: Statewide Radio Interoperability Needs Assessment, Macro Corporation and The State of Arizona, 2004, pp. 16. Trunking is used by many government entities to provide two-way communication for fire departments, police and other municipal services, who all share spectrum allocated to a city, county, or other entity.

The forward engine exhausted under the centre fuselage and the rear engine exhausted at the end of the rear fuselage. Access to the engines for maintenance and removal was gained by removing the forward fuselage forward of the nose undercarriage and the rear fuselage forward of the fin. The main and nose undercarriages were housed entirely within the fuselage. The nose undercarriage rotated 90° to lie flat under the forward engine, and the twin wheeled main undercarriage legs, with long travel levered suspension, retracted into the centre fuselage above the forward jet pipe and astride the fuel tank and intake trunking for the rear engine.

If the bell will not seal at depth, the divers may need to replace the door seal, and may have to check all valves on through-hull penetrations and close any which may be causing the leak. If the leak is only noticed during ascent, the bell may be returned to working depth for the divers to assess the problem and do these tasks. If a seal cannot be re-established at depth another bell must be sent down to rescue the divers. If the leak starts at the surface, the supervisor would attempt to maintain internal pressure while the bell would be reconnected to the trunking.

Although IPTV and conventional satellite TV distribution have been seen as complementary technologies, they are likely to be increasingly used together in hybrid IPTV networks that deliver the highest levels of performance and reliability. IPTV is largely neutral to the transmission medium, and IP traffic is already routinely carried by satellite for Internet backbone trunking and corporate VSAT networks.Berlocher, Greg and Freyer, Dan. "IP And Satellite: Communications Worlds Merging" Via Satellite January 2009 p 24–28 The use of satellite to carry IP is fundamental to overcoming the greatest shortcoming of IPTV over terrestrial cables – the speed/bandwidth of the connection, as well as availability.

Automatic pressure relief valves were placed at the bottom of the gasbags: there was no trunking to carry vented hydrogen to the top of the craft and waste gas simply diffused upwards in the space between gasbags and the covering, whose top surface was left undoped to allow the hydrogen to escape. Some gasbags were also fitted with a manually operated manoeuvering valve at the top.Robinson 1973, pp.96-100 The ship was controlled from the forward gondola, which was divided into two structurally separate sections in order to avoid transmission of engine vibration to the crew accommodation: the small gap between the two sections was faired over with fabric.

The Berkeley Software Distribution UNIX operating systems (e.g., NetBSD, OpenBSD, and FreeBSD) continue active development of ifconfig and extension of its functionality to cover the configuration of wireless networking interfaces, VLAN trunking, controlling hardware features such as TSO or hardware checksumming or setting up bridge and tunnel interfaces. Solaris has historically used ifconfig for all network interface configuration, but as of Solaris 10 introduced dladm to perform data-link (OSI model layer 2) configuration, reducing ifconfig's purview to IP configuration. In older Linux distributions, ifconfig, in conjunction with the utility route, was used to connect a computer to a network, and to define routes between networks.

CommWorks/3Com co- developed an H.323-based softswitch with AT&T; in 1998 for use in a "transparent trunking" application for AT&T;'s residential long-distance customers. Long distance telephone calls were redirected from the LEC's ingress CLASS 5 switch to the Total Control 1000 media gateway, where it was converted from TDM to IP and transported across AT&T;'s WorldNet IP backbone. When it reached the destination, it was passed to the egress LEC's CLASS 5 switch as an untariffed data call. CommWorks modified the gateway and softswitch software to support SIP for MCI/WorldCom's hosted business offering in 2000.

The system can be permanently placed on a ship or ocean platform, but is more commonly capable of being moved from one vessel to another by crane. The entire system is managed from a control room (van), where depth, chamber atmosphere and other system parameters are monitored and controlled. The diving bell is the elevator or lift that transfers divers from the system to the work site. Typically, it is mated to the system utilizing a removable clamp and is separated from the system tankage bulkhead by a trunking space, a kind of tunnel, through which the divers transfer to and from the bell.

The concept of trunking (resource sharing) is actually quite old, and is taken from telephone company technology and practice. Consider two telco central office exchanges, one in town "A" and the other in adjacent town "B". Each of these central offices has the theoretical capacity to handle ten thousand individual telephone numbers. (Central office "A", with prefix "123", has available 10,000 numbers from 123-0000 to 123-9999; central office "B", with prefix "124", the same.) If all 10,000 subscribers in "A" were to simultaneously call 10,000 subscribers in "B", then it would be necessary to have 10,000 lines (in telco parlance "trunk lines", or simply "trunks") to connect the two towns.

In November 1954, the Bell System Technical Journal published an article entitled "In-Band Single- Frequency Signaling", which described the process used for routing telephone calls over trunk lines with the then-current signaling system, R1. The article described the basics of the inter-office trunking system and the signals used to start, route, and end calls. In November 1960, further technical details were disclosed in the Bell System Technical Journal in an article entitled Signaling Systems for Control of Telephone Switching. This article identified the specific single frequency (SF) and multi-frequency (MF) tones used to start and end calls, and to transmit the called number, on a long-distance connection.

Versions of the Altay system are still in use today as a trunking system in some parts of Russia. In 1959 a private telephone company in Brewster, Kansas, USA, the S&T; Telephone Company, (still in business today) with the use of Motorola Radio Telephone equipment and a private tower facility, offered to the public mobile telephone services in that local area of NW Kansas. This system was a direct dial up service through their local switchboard, and was installed in many private vehicles including grain combines, trucks, and automobiles. For some as yet unknown reason, the system, after being placed online and operated for a very brief time period, was shut down.

It is assumed to be the responsibility of the party ordering the initial installation of a service to cover the cost of providing isolation links, service isolating devices, and clearly marked trunking for running cables, and all should be part of the planning process. In some circumstances (such as when a 'cold' site is upgraded to 'hot' status), the Zone of Influence may encompass residential or commercial property which is not within the property of the Electrical Supply Industry. In these cases the cost of retroactively protecting each telephone circuit may be prohibitively high, so a drainage electrode may be supplied to effectively bring the local Earth Potential back to safe levels.

Trunked radio takes advantage of the probability that with any given number of user units, not everyone will need channel access at the same time, therefore fewer discrete radio channels are required. From another perspective, with a given number of radio channels, a much greater number of user groups can be accommodated. In the example of the police department, this additional capacity could then be used to assign individual talk groups to specialized investigative, traffic control, or special-events groups which might otherwise not have the benefit of individual private communications. To the user, a trunking radio looks just like an "ordinary" radio: there is a "channel switch" for the user to select the "channel" that they want to use.

Thus the process involves only one ascent, thereby mitigating the time-consuming and comparatively risky process of in-water, staged decompression normally associated with non- saturation mixed gas diving or sur-D O2 operations. More than one living chamber can be linked to the transfer chamber through trunking so that diving teams can be stored at different depths where this is a logistical requirement. An extra chamber can be fitted to transfer personnel into and out of the system while under pressure and to treat divers for decompression sickness if this should be necessary. The divers use surface supplied umbilical diving equipment, utilizing deep diving breathing gas, such as helium and oxygen mixtures, stored in large capacity, high pressure cylinders.

Services are provided by Great Western Railway. There are suburban stations on the main line at Oldfield Park and Keynsham which have a limited commuter service to Bristol. Green Park station was once operated by the Somerset & Dorset Joint Railway, whose line (always steam driven) climbed over the Mendip Hills and served many towns and villages on its run to Bournemouth; this example of an English rural line was closed by the Beeching cuts in March 1966, with few remaining signs of its existence, but its Bath station building survives and now houses a number of shops. The 2004 Bristol/Bath to South Coast Study was commissioned as a result of the de- trunking in 1999 of the A36/A46 trunk road network from Bath to Southampton.

After the introduction of the new road numbering system, some Trunk Roads (either in whole or in part) were downgraded to Regional roads, effectively 'de-trunked'Trunk road#De-trunking: Ireland. A notable feature of the former system was multiplexing (or concurrency), where a section of road was designated by two or more route numbers. Examples of multiplexes include the T7/T12 multiplex between New Ross and Waterford, the T6/T13 multiplex between Cahir and Kilheffernan (east of Clonmel), the T28/T36 multiplex between Newcastlewest and Abbeyfeale and the short T19/T21 multiplex between Thurles and Toor. The road between Cavan, Butlersbridge, Cloverhill and the border with Northern Ireland (near Wattle Bridge in County Fermanagh) was a triple multiplex of the T10, T15 and T35 routes.

A trunk line is a circuit connecting telephone switchboards (or other switching equipment), as distinguished from local loop circuit which extends from telephone exchange switching equipment to individual telephones or information origination/termination equipment.Title 47 of the Code of Federal Regulations, Parts 0-199 Trunk lines are used for connecting a private branch exchange (PBX) to a telephone service provider.Versadial, Call Recording Terms/Definitions, last accessed 8 June 2015 When needed they can be used by any telephone connected to the PBX, while the station lines to the extensions serve only one station telephones. Trunking saves cost, because there are usually fewer trunk lines than extension lines, since it is unusual in most offices to have all extension lines in use for external calls at once.

A mass call event or mass calling event (also MCE in telephony usage) is a situation in which an extraordinarily high number of telephone calls are attempted into or out of an area, causing tremendous network congestion, and therefore service which is either significantly degraded or potentially almost completely unavailable. The term is typically used with mobile telephony systems, in which there are simply not enough radio channels available in a given cell or cells. This causes blocked calls or dropped calls. However, it can also apply to landline phones, in which not enough trunking telephone circuits are available into and out of any given telephone exchange or equivalent switching office at any level of the public switched telephone network (PSTN).

The most novel part of the conception of the exchange design was the use of pulse amplitude modulation and time division multiplex techniques for the transmission of up to one hundred conversations over a common channel, which was well ahead of its time. This technique would eventually be used in System X and other digital exchanges as technology caught up. Another interesting feature of the installation was the use of time-sharing in the setting-up of the calls and in their control, which was something that all subsequent digital exchange design would follow. At the time in Strowger exchanges ranks of selectors were interconnected by means of a complex trunking system dictated by the method of setting up the calls and by the need to economise in the total number of switching points.

Although historically a rural and agricultural area, it is now a dormitory village for Luton and the surrounding region, as it is a short distance from the M1 motorway. Lying on Watling Street, the Roman road (subsequently the A5 until de-trunking) between St Albans and Dunstable, it was a major coaching stop on the highway from London to Birmingham, at one point having over forty inns and public houses along its main road, and the village was one of the earliest sites of the Pickfords transport service, one road out of the village being named Pickford Road. During the 12th century Christina of Markyate was the Prioress of a Benedictine community in the area. The village lies near the junction of the A5183 Watling Street (formerly A5) and the B4540 (for Luton and Caddington).

Version 4 (RFC 3010, December 2000; revised in RFC 3530, April 2003 and again in RFC 7530, March 2015), influenced by Andrew File System (AFS) and Server Message Block (SMB, also termed CIFS), includes performance improvements, mandates strong security, and introduces a stateful protocol. Version 4 became the first version developed with the Internet Engineering Task Force (IETF) after Sun Microsystems handed over the development of the NFS protocols. NFS version 4.1 (RFC 5661, January 2010; revised in RFC 8881, August 2020) aims to provide protocol support to take advantage of clustered server deployments including the ability to provide scalable parallel access to files distributed among multiple servers (pNFS extension). Version 4.1 includes Session trunking mechanism (Also known as NFS Multipathing) and available in some enterprise solutions as VMware ESXi.

On 3 April 1986 she suffered a catastrophic gearbox failure which almost saw the end of the vessel's naval career. Just starting out on her "fly the flag" around the globe trip, at about 23:30 whilst reaching full engine revs, due to an over tightened clamp causing friction and heat it ignited the oil vapour within the gearbox exploded causing a fire lasting well over four hours. Sea Harriers were flown off whilst firefighting continued below decks, and one Sea king took the only casualty ashore (smoke inhalation) Although it was a serious fire it was contained within the forward gearbox room and vertical trunking. Additional vessels including the destroyer HMS Nottingham and Ferry Sea Leopard were in attendance, however Illustrious crew managed to extinguish the fire and she returned to Portsmouth under her own power provided by her aft engine room.

The sender concept was developed to meet the needs of large city telephone switching systems, where the total number of subscriber lines and multiple central offices throughout the city required complex switching arrangements that were not easily handled by the direct control systems then in use, such as the step by step, or Strowger system. These limitations included inefficient trunking in large service areas, and a limited ability for growth and reorganization as additional subscribers were added. The introduction of senders into switching systems allowed the subscriber's dial pulses to be registered, then translated into a physical location on the switching fabric, either in the local office, or in a distant office. Once the sender received the translation, it directed the selectors in the switching fabric to the correct terminal, completing the connection to the called party.

Call origination, also known as voice origination, refers to the collecting of the calls initiated by a calling party on a telephone exchange of the PSTN, and handing off the calls to a VoIP endpoint or to another exchange or telephone company for completion to a called party. In the VoIP world, the opposite of call origination is call termination, where a call initiated as a VoIP call is terminated to the PSTN. The term is often used in referring to a VoIP trunking service that provides the ability for calls to originate on the PSTN and be delivered to a customer's VoIP endpoint. It is often referred to as "DID" (for Direct Inward Dialing) which more properly refers to a service entirely within the PSTN where individual PSTN numbers can terminate on a customer's PBX.

The other two cellular operators launch a PTT service similar in function to the one offered by Bravo through its digital trunking network, but the former companies used a technology called PoC for this service. In neighboring Jordan, Bravo-Telecom's sister company XPress operates the same system, which enables customers in both sides to place international PTT calls, The company was owned by two shareholders, a local company called NASCO and the Dubai-based Wataniya Int'l which was later wholly acquired by Qatar-based Ooredoo in 2007. In 2013, Bravo was acquired by the Saudi Telecom Company, Saudi Arabia's dominant telecommunications carrier, but continues operating a separate network in parallel to the "Unified Secure Communication Network of Saudi Arabia" (USeC) of the Ministry of the Interior. In 2017, Bravo announced plans to acquire professional mobile radio (PMR) infrastructure from Airbus.

In addition, as costs come down, it is possible to add advanced squelch capabilities such as CTCSS (analog squelch) and DCS (digital squelch) (often marketed as "privacy codes") to inexpensive radios, as well as voice scrambling and trunking capabilities. Some units (especially amateur HTs) also include DTMF keypads for remote operation of various devices such as repeaters. Some models include VOX capability for hands-free operation, as well as the ability to attach external microphones and speakers. Consumer and commercial equipment differ in a number of ways; commercial gear is generally ruggedized, with metal cases, and often has only a few specific frequencies programmed into it (often, though not always, with a computer or other outside programming device; older units can simply swap crystals), since a given business or public safety agent must often abide by a specific frequency allocation.

As of September 2015 extensive maintenance work is being carried out on this span in order to replace wasted plates within the girders, and this work is expected to carry on until the end of the year. Originally the lineside telegraph wires were carried along the eastern wall of the viaduct on wooden trunking, except where they were carried over the previously mentioned iron-girder span in structure 350. A telegraph pole, sat on top of the masonry of the parapet wall and guyed appropriately, was provided a short distance from each end of this span, and the circuits were then carried over the span between the two poles. Although little sign of these poles remains from on top of the viaduct, the remains of the guying on the exterior of the parapet wall can still be clearly seen from the reservoir.

There is a door or hatch at the access opening to the forechamber, the main chamber, both ends of a medical or stores lock, and at any trunking to connect multiple chambers. A closed bell has a similar hatch at the bottom for use underwater and may have a side hatch for transfer under pressure to a saturation system, or may use the bottom hatch for this purpose. The external door to the medical lock is unusual in that it opens outward and is not held closed by the internal pressure, so it needs a safety interlock system to make it impossible to open when the lock is pressurised. Viewports are generally provided to allow the operating personnel to visually monitor the occupants, and can be used for hand signalling as an auxiliary emergency communications method.

With the beginning of the jet age, the need for clearance for the propeller was replaced with the need to provide a clear path for hot exhaust gases. Jet engine efficiency was hampered by long intake and exhaust trunks, as were used on many early designs, and one solution was to use twin booms to shorten the exhaust trunking to the minimum, such as de Havilland used on their successful Vampire and Venom jet fighters. A small number of designs used twin booms for other reasons, most notable being the Lockheed P-38 Lightning, whose booms contained the overly lengthy engine turbo-superchargers, which would have made for an unusually long nacelle. The final use for a twin boom to be developed was in tying together very high aspect ratio wings and canards as on the Rutan Voyager, to reduce flexing, and the weight needed to otherwise constrain it.

A closed bell handling system is used to move the bell from the position where it is locked on to the chamber system into the water, lower it to the working depth and hold it in position without excessive movement, and recover it to the chamber system. The system used to transfer the bell on deck may be a deck trolley system, an overhead gantry or a swinging A-frame. The system must constrain movement of the supported bell sufficiently to allow accurate location on the chamber trunking even in bad weather. A bell cursor may be used to control movement through and above the splash zone, and heave compensation gear may be used to limit vertical movement when in the water and clear of the cursor, particularly at working depth when the diver may be locked out and the bell is open to ambient pressure.

The TSPS system utilized special analog trunks that originated at Class 5 end office circuit switch systems and Class 4 toll access circuit switch systems that were connected to Class 3 primary toll circuit switch systems such as the 4A-ETS/PBC and 4ESS switch systems. The TSPS system did not perform switching between the originating end office switch and the toll switch for the subscriber voice path. The TSPS system included the "Remote Trunking Arrangement" (RTA) feature that consolidated the trunk connection at the originating switch and provided a switched connection to a telephone operator only as required for a short duration at the beginning of a call to obtain billing information or at the end of a call in which the caller requested "time and charges". The TSPS system provided a temporary switched connection to a toll operator who helped facilitate calls requiring human assistance such as person-to-person, collect, third-party-billed, and hotel billing.

"Trunked" radio systems differ from "conventional" radio systems in that a conventional radio system uses a dedicated channel (frequency) for each individual group of users, while "trunking" radio systems use a pool of channels which are available for a great many different groups of users.The document "Conventional and Trunked Radio Systems Comparison Report" from the Department of Homeland Security analyzes and compares conventional, trunked, and hybrid LMR systems and provides high-level definitions of the architecture alternatives associated with each option. For example, if police communications are configured in such a way that twelve conventional channels are required to permit citywide dispatch based upon geographical patrol areas, during periods of slow dispatch activity, much of that channel capacity is idle. In a trunked system, the police units in a given geographical area are not assigned a dedicated channel, but instead are members of a talk-group entitled to draw upon the common resources of a smaller pool of channels.

In 2009, SES and Middle East satellite operator Yahsat announced the formation of a joint venture, YahLive, to commercialise 23 Ku-band transponders on Yahsat 1A, serving the Middle East, North Africa and Western Asia with direct-to-home TV services. Also in 2009, SES announced its investment in O3b Networks a project to build a medium Earth orbit (MEO) satellite constellation to deliver high-speed, low-latency, fibre-like internet broadband trunking to the world's emerging regions ("the Other 3 billion"). In 2010, SES grew its stake in SES Sirius to 100% and closed the acquisition of the in-orbit satellite Protostar-2/Indostar-2, renaming it SES-7 and integrating it into its fleet covering India and Southeast Asia. In May and September 2011, SES restructured and rebranded the company to streamline the organisation's activities under a single management team and one main brand (SES), incorporating the company's two previous operating entities, SES Astra and SES World Skies.

The initial Connoisseur car was thoroughly rebuilt in a fashion similar to the regular InterCity big window cars, with a replacement of the windows either side of the coupe area as they did not conform to the standard big window measurements, 51 Addington seats arranged in bays of four, across tables, alcove-style, to replace the previous 32 seats, plus an improved Pressure Ventilation system and associated ceiling trunking, "new" bogies and removal of the "kitchenette"/coupe to facilitate the increase in seating space among other detail improvements. The same year of the introduction of the second Connoisseur car, this newer vehicle was taken north for interim use on the North Island Main Trunk (NIMT)'s "new" Overlander daylight passenger services, made up of existing Northerner rolling stock and allow for the relocation of the Silver Fern railcars to other services. The carriage never returned to duty as The Connoisseur carriage on the TranzAlpine Express. In 1993, it was refitted with 39 seats to a newer design and arranged in a forward-facing format for the NIMT.

French Battleships 1922-1956, John Jordan & Robert Dumas, Seaforth Publishing, Except for the emergency conning tower at its base, and the trunking for the main gun directors mounted on top, the superstructure was lightly armoured against splinters only, to save weight. Additional weight- saving design measures included the use of light materials such as aluminium for fittings, and fir instead of teak for deck planking, although subsequently, teak decks were fitted in the late 1920s, following concerns that the ships could not fire a full broadside without causing structural damage to the decks. The Nelson class was a revolutionary but compromised design, and unsurprisingly there were shortcomings. The location of the superstructure towards the stern caused manoeuvrability problems in high winds, especially when steaming at low speeds, where the superstructure acted somewhat like a mizzen sail permanently set, causing the ships to "weathervane" but according to Captain Hugh Binney, who commanded Nelson in the late twenties, "if this is kept in mind, no real difficulties should be encountered in any circumstances".

Upon physically connecting a device to a port of a switch configured as a VLAN Management Policy Server (VMPS) client, the switch begins listening for packets, and encapsulates and rebroadcasts the first packet received into a VQP packet, which is sent to one of up to two configured VMPS servers on port udp/1589. The VMPS server will give one of 4 responses (`Allow`, `Deny`, `Shutdown`, `Wrong_Domain`) and the switch will either assign the port to the appropriate VLAN, put the port back into the pre-confirmation state, shut down the port until the device or another one is physically reconnected, or log an error indicating that it is incorrectly configured. The latter result is often due to Cisco documentation failing to mention that the domain name in the VMPS configuration file must match the VLAN Trunking Protocol (VTP) domain name. If reconfirmation of VLAN assignment is required, it is done in the same manner as initial confirmation, with the exception of including the currently assigned VLAN for the port in the VQP packet.

Hammond tried to push his unconscious partner inside; unable to do so, he pulled Hoffman away from the hatch, and crawled through the trunking into the bell. Sitting on one of the seats, he drew Hoffman's body part way into the bell, positioned his arms over his knees and began ventilating him, giving mouth-to-mouth resuscitation.” Minutes later, surface-to-bell communications unexpectedly broke down. A little over a year later, Pettit said in Court that, after Hammond got back into the bell and worked on Hoffman for a while, communications began to deteriorate “and at one point it had completely disappeared and at that point I had to leave and see if we could get some help from ashore.” Pettit phoned his company office and gave General Manager Stanley Kellogg details of his predicament—that he had lost contact with the bell and “couldn’t take a chance bringing it to the surface when the doors were open.” Kellogg offered advice and after the conversation ended, notified the Department of Energy, contacted Offshore Medical Support, and began calling rescue vessels.

Pettit ordered Hammond to recover Hoffman's body inside the bell, but Hammond was unable to do so. When asked at the Inquiry what the problem was, he answered: “Well, he weighed almost as much as I did and plus the fact he was wearing a hot-water suit is quite a heavy piece of material, that added to his own weight and the fact that it was totally a dead weight, no help at all involved and I had a very limited space to work in, I couldn’t pull him in all the way.” Pettit asked if Hoffman was dead and Hammond said that he was. By that time Hoffman had not been breathing for 60 minutes, and with the threat of losing bell communications, Pettit asked Hammond to “drop back down into the trunking and lash Craig’s body to the outside of the bell…and they would then bring the bell to the surface.” When the bell arrived at the surface, a diver was lowered into the water to free Hoffman's body and swim it to a recovery basket.

According to Avaya, the Norstar/BCM systems and telephone sets would eventually integrate with the Avaya IP Office via Avaya Aura. Nortel features and programming would be preserved, but would accompany Avaya features and programming as well.Avaya Product Roadmap Press Release --> Subsequently, over 3+ years - from January of 2010 into July of 2013 - Avaya announced the discontinuation of the entire Nortel product line of small, medium and enterprise business telephone systems thus stranding tens of millions of long-time users of legacy Nortel communications and networking products. Model i2004 IP set that can be used on BCM and CS1000/2100 Nortel/Avaya systems For clients that want to move from the Norstar digital system format to a VOIP format, Nortel BCM is the replacement product recommended by Nortel/Avaya. BCM uses all of the feature codes, and calling features of the older Norstar systems and integrates them into a Digital/VOIP format that with RLS3.0 and further, allows SIP trunking, Unified Messaging and the use of Nortel M7000 digital telephones, "T" Series Business Sets, i2004 sets, series 1200 VOIP sets, and the high end 1100E VOIP series sets, such as the Bluetooth compatible Nortel IP Phone 1140E SIP telephone series VOIP telephones.
