Abstract
The current invention provides methods for relieving congestion associated with interfacing multiple types of subscriber link traffic, i.e. voice, voice-band data, and broad-band data, with a network such as the public switched telephone network (PSTN). In an embodiment of the invention waste of modem resources is diminished by reducing the magnitude of the transmission parameters between a data terminal and modem resources during intervals of reduced data flow. This frees scarce modem resources for other sessions. In another embodiment of the invention the time required to initiate session setup is reduced. This reduces the time devoted by modem facilities to call setup at the start of session, or after an idle period.
