DLCI

DLCI

(Data Link Connection Identifier) The number of a private or switched virtual circuit in a frame relay network. Located in the frame header, the DLCI field identifies which logical circuit the data travels over, and each DLCI has a committed information rate (CIR) associated with it. The DLCI number is local to the FRAD and frame relay switch it connects to, and it is generally changed by the switch within the network, because the receiving switch uses a different DLCI for the same connection. See CIR, PVC, SVC and frame relay.

Guaranteed Bandwidth Facility and prioritization of data allows mission critical and client server data to be intelligently merged onto a single DLCI
The Virtual Network Interrogation Protocol (VNIP) provides the basis for advanced frame relay diagnostics such as end-to-end DLCI mapping and logical PVC loopbacks.
The Generator/Analyzer module can automatically identify up to 2,040 substreams from an incoming stream based on identifiers such as VPI/VCI for ATM or DLCI for Frame Relay.
