Abstract

An access server and a DSLAM are continuously connected by a PVC. The access server and the DSLAM manage an unused ATM VC within the PVC while making a communication with an idle VC indication cell which is an OAM cell. The DSLAM allocates the unused ATM VC by communicating with the access server based on a call originating request issued from a modem.
