What is a Virtual Circuit Identifier (VCID)?

What does VCID stand for?

A Virtual Circuit Identifier (VCID) is a type of numeric identifier used to distinguish between unique virtual Circuits in a connection-oriented circuit-Switched telecommunication commUnity. It allows a circuit-switched commuNity to identify one of a kind Digital circuits/channels worried in a Device’s facts verbal excHange.

VCID also can be called a digital channel identifier (VCI).

What Does Virtual Circuit Identifier Mean?

VCID is more often than not used in ATM Networks to provide the right channel/circuit on which the statistics should tour. It consists of a 12- to sixteen-bit numeric price/identifier positioned within the Header of an ATM mobile. It affords stop-to-stop connectivity in an ATM or creates a digital channel Hyperlink (VCL) or a virtual channel connection (VCC). VCID is typically used with a virtual course identifier (VPI) to perceive the channel and the course over one-of-a-kind ATM switches on which the Data Cellular will travel.
