In carrier sense multiple access with collision avoidance (CSMA/CA) networks and in carrier sense multiple access with collision detection (CSMA/CD) networks, the algorithm used to schedule retransmission after a collision such that the retransmission is delayed by an amount of time derived from the slot time and the number of attempts to retransmit.

The deletion or omission of a leading or a trailing portion of a string in accordance with specified criteria.

In the representation of a number, the error introduced when one or more digits are dropped.

1. In a communications network, a single transmission channel between two points that are switching centers or nodes, or both.
2. [A] circuit between switchboards or other switching equipment, as distinguished from circuits which extend between central office switching equipment and information origination/termination equipment. [47 CFR Pt.36-A]

A unique identity assigned to each SS7 message trunk interconnecting two switches. [T1.226-1992]

A bulk encryption device used to provide secure communications over a wideband digital transmission link.
Note: A TED is usually located between the output of a trunk group multiplexer and a wideband radio or cable facility.

The Trunk Gateway provides an access interface between traditional Public Switched Telephone Network (PSTN) circuit-based networks and packet networks. Examples of the PSTN trunk interfaces are Integrated Services Digital Network (ISDN) User Part (ISUP), Primary Rate Interface (PRI), Multi Frequency (MF) and Digital Tone Multi Frequency (DTMF). The Trunk Gateway may also support an interface for line based Generic Requirement… (Read More →)

Two or more trunks of the same type between two given points.

A time-division multiplexer that combines individual digital trunk groups into a higher rate bit stream for transmission over wideband digital communications links.

A unique alphanumeric code used to identify a trunk group. [T
