PURPOSE: The PRI(Primary Rate Interface) interfacing method for an AODI(Always On Dynamic ISDN) service in an exchange, is provided to recognize a PRI(Primary Rate Interface) line and a channel number having an AO(Analog Output) channel through an independent AO channel table, so that an AO call and a DI(Digital Input) call can be simultaneously included in one PRI. Accordingly, a network service provider can distribute the AO channel to many RASs(Remote Access Servers). CONSTITUTION: A table for storing an AO(Analog Output) B-channel configured in a PRI(Primary Rate Interface) for an AODI(Always On Dynamic ISDN) service is generated for management(S1). Hunting for an AO channel is performed according to a characteristic of a packet call, to selects the PRI B-channel for AO(S2). If the AO call is attempted to the PRI B-channel for AO in an RAS(Remote Access Server), a nailed up function is supported(S3). |
