Definitions for "Data Link Connection Identifier"
Keywords:  dlci, relay, lcn, dlc, header
The identifier of the virtual circuit number in the frame relay header. The default DLCI field consists of 10 bits, allowing for 1024 virtual circuits across each interface. The field may be made larger by use of the extended address (EA) bits. Click here to display a diagram.
A number given to a DLC - part of the frame-relay packet header that is used to name the logical channel the frame will be routed to. The header has space for 10 bits of data - this DLCI is embedded in the data stream from beginning to end of the transmission, and the values are different for every individual router in a network. Very similar to a Logical Channel Number (LCN) - and performs the same tasks as a LCN.
The address used in frame relay networks.
