1 increases the number of Data Link Connection Identifiers (DLCIs) from 256 to 440, nearly doubling the number of logical connections supported in a frame relay network.
On Frame Relay links, the NetScout Probe automatically discovers Data Link Connection Identifiers (DLCIs) and Committed Information Rates (CIRs) and gives customers the flexibility to view the entire link or drill down to an individual DLCI.
Approved by the Frame Relay Forum in March 1995, the Service Interworking Implementation Agreement defines how frame relay data link connection identifiers (DLCIs) to ATM virtual path/virtual channel identifiers (VPI/VCIs).
