Abstract: A fixed cellular terminal (FCT) (30) includes a packet-service unit (154), an analog line interface (120), and a packet-service/analog line gateway (68). The packet-service unit facilitates radio frequency communication over an air interface with a cellular telecommunications network and provides, amongst others, a packet-service such as GPRS service. The analog line interface is connected to a modem in a terminal equipment unit (50). The packet-service/analog-line gateway (68) enables use of the packet-switched service on the analog line interface (120) and implements a layer 2 point-to-point protocol over the layer 1 analog modulations in a FCT modem (121), thereby providing the FCT with the protocol that the terminal equipment (TB) normally requires on the remote side of a circuit-switched connection. Also, the packet-service/analog-line gateway includes a sequence interpreter (150) which recognizes predetermined gateway-controlling sequences on the analog line (46).
