This is about the network design strategies for riding in auto cargo space, see Trunking auto , and for the UK term for electrical wireways, see Electrical conduit Trunking . In modern communication s, trunking is a concept by which a communications system can 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 VHF radios commonly used by police agencies. More recently port trunking has been applied in computer networking as well.

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 Virtual LAN VLAN aware Network switch switches , and for negotiating the type of trunking Encapsulation networking encapsulation to be used. It works on the Data Link Layer Layer 2 of the OSI model . VLAN trunks formed using DTP may utilize either IEEE 802.1Q or Cisco Inter Switch Link Cisco ISL trunking protocols. DTP should not be confused with VLAN Trunking Protocol VTP , as they serve different purposes. VTP communicates VLAN existence information between switches. DTP aids with trunk port establishment. Neither protocol transmits the data Frame telecommunications frames that trunks carry. Switch port modes The following switch port mode settings exist auto &mdash causes the port to passively be willing to convert to trunking. The port will not trunk unless the neighbor is set to on or desirable . This is the default mode. Note that auto auto both ends default links will not become trunks. on &mdash forces the link into permanent trunking, even if the neighbor doesn t agree. off &mdash forces the link to permanently not trunk, even if the neighbor doesn t agree. desirable &mdash causes the port to actively attempt to become a trunk, subject to neighbor agreement neighbor set to on , desirable , or auto . nonegotiate &mdash Disables the sending of DTP frames on the port. For use when the DTP frames confuse the neighboring non Cisco 802.1Q switch. It does not set the port to trunking mode automatically.

It allows grouping several physical Ethernet links into one logical Ethernet link to provide fault tolerance and high speed links between routers, switches, and servers. In the past redundant links were unused due to Spanning tree protocol Spanning Tree s loop protection. Using this technology allows or enables the use of several links from 2 up to 8 and combined them to create increased bandwidth and several fail over paths. This produces server to switch or switch to switch connections that are up to 8 times faster. Fault tolerant design is an important aspect of Multi Link Trunking technology. Should any one or more than one link fail, the MLT technology will automatically redistribute traffic across the remaining links.

The GoTA system was developed by ZTE , a Chinese manufacturer. The GoTA system can be used for both private and public trunking network applications. GoTa is capable of providing a variety of trunking services One to one private calls and one to many group calls The ability to set the user s priority The ability to perform forced insertion forced release based on the user s priority The ability to provide special services such as system paging, group paging, sub group paging, and dedicated Push to talk Push To Talk services as required The ability to classify the groups into permanent and temporary groups, in which the group members can be managed by the user. In addition to trunking service, GoTa can provide value added services such as short messages, location based services and other data services. The original GoTa standard was developed for the CDMA frequency bands 800 MHz band. GoTa is adapted to work in the 450 MHz band as well.

In telecommunication s, a call collision commonly known as glare is one of two things The contention that occurs when a terminal telecommunication terminal and data Telecommunication circuit circuit terminating equipment Data Communications Equipment DCE specify the same channel communications channel at the same time to Call transfer transfer a telephone call call request and handle an incoming call. When call collision occurs, the DCE proceeds with the call request and cancels the incoming call. The condition that occurs when a trunking trunk or channel is seized at both ends simultaneously. If you have ever tried to make a call out on a PBX, and been accidentally connected to an incoming call, you have experienced glare. This can sometimes happen at home too, if you pick up your phone to make a call out at the exact second that a call is about to start ringing in. Multi line hunting generally avoids glare by picking trunks in opposite preference order so the highest numbered line, which is last choice for incoming calls, is first choice for outgoing calls, like so pre incoming 1 2 3 4 5 6 7 8 outgoing pre For PBX trunks, glare can further be reduced by using ground start trunking. IE Nortel BSP discourages using loop start trunks for this and other reasons. Long Distance exchanges in the 1950s and 60s incorporated Glare Detectors to alleviate the problem.
