Abstract
Mobile terminated calls arriving at a network access server configured as an Interworking function (IWF) are routed to a particular modem in the network access server by means of a table maintained at the interface to a communications network receiving the call. The table maps called party numbers (or call reference values uniquely assigned to each call) to a particular modem channel number and slot number for a modem that has already been assigned to the call.
