  2. Trunked radio system - Wikipedia

    en.wikipedia.org/wiki/Trunked_radio_system

    A trunked radio system is an advanced alternative in which the channel selection process is done automatically, so as to avoid channel conflicts and maintain frequency efficiency across multiple talkgroups. This process is handled by what is essentially a central radio traffic controller, a function automatically handled by a computer system.

  3. Multi-link trunking - Wikipedia

    en.wikipedia.org/wiki/Multi-link_trunking

    Multi-link trunking (MLT) is a link aggregation technology developed at Nortel in 1999. 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.

  4. Trunking - Wikipedia

    en.wikipedia.org/wiki/Trunking

    Trunking in telecommunication originated in telegraphy, and later in telephone systems where a trunk line is a communications channel between telephone exchanges. Other applications include the trunked radio systems commonly used by police agencies. [1] In the form of link aggregation and VLAN tagging, trunking has been applied in computer ...

  5. Network topology - Wikipedia

    en.wikipedia.org/wiki/Network_topology

    If a message is intended for a computer partway down the line, each system bounces it along in sequence until it reaches the destination. A daisy-chained network can take two basic forms: linear and ring. A linear topology puts a two-way link between one computer and the next. However, this was expensive in the early days of computing, since ...

    The interconnection between the two domains must occur through a SIP trunk. [ citation needed ] The interconnection between the two domains, created by transport via the Internet Protocol (IP), involves setting specific rules and regulations as well as the ability to handle some services and protocols that fall under the name of SIP trunking.
