R2 signalling

Index R2 signalling

R2 - Specifications of Signalling System R2 is a 1950s- and 1970s-era channel-associated-signalling signalling protocol used outside of the former Bell System to convey information along a telephone trunk between two telephone switches in order to establish a single telephone call along that trunk.

Analog signal

An analog signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal.

Bell System

The Bell System was the system of companies, led by the Bell Telephone Company and later by AT&T, which provided telephone services to much of the United States and Canada from 1877 to 1984, at various times as a monopoly.

Channel-associated signaling

Channel-associated signaling (CAS), also known as per-trunk signaling (PTS), is a form of digital communication signaling.

Client–server model

The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients.

Communication protocol

In telecommunication, a communication protocol is a system of rules that allow two or more entities of a communications system to transmit information via any kind of variation of a physical quantity.

Compelled signalling

The term compelled signalling refers to a class of telecommunications signalling protocols where receipt of each discrete signal needs to be explicitly acknowledged before the next signal is able to be sent.

Digital data

Digital data, in information theory and information systems, is the discrete, discontinuous representation of information or works.

Digital Signal 0

Digital Signal 0 (DS0) is a basic digital signaling rate of 64 kilobits per second (kbit/s), corresponding to the capacity of one analog voice-frequency-equivalent communication channel.

Echo suppression and cancellation

Echo suppression and echo cancellation are methods used in telephony to improve voice quality by preventing echo from being created or removing it after it is already present.

Millisecond

A millisecond (from milli- and second; symbol: ms) is a thousandth (0.001 or 10−3 or 1/1000) of a second.

Multi-frequency signaling

In telephony, multi-frequency signaling (MF) is a signaling system that was introduced by the Bell System after World War II.

Peer-to-peer

Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers.

Postal, telegraph and telephone service

A postal, telegraph, and telephone service (or PTT) is a government agency responsible for postal mail, telegraph, and telephone services.

Prosleptic syllogism

A prosleptic syllogism (from Greek πρόσληψις proslepsis "taking in addition") is a class of syllogisms that use a prosleptic proposition as one of the premises.

Register signaling

In telecommunications, register signaling provides addressing information, such as the calling and/or called telephone number.

Trunking

In telecommunications, trunking is a method for a system to provide network access to many clients by sharing a set of lines or frequencies instead of providing them individually.

United States

The United States of America (USA), commonly known as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major self-governing territories, and various possessions.
