sending/receiving data. The frame relay DCE (switch) should report a DLCI as
active only when it has a path through the frame relay network. The status of a
DLCI will be reported as
this is the first time it is being reported to the DTE. A DLCI reported as active
will (if not already done) transition the frame relay DLCI on the Virtual Con-
