Abstract:
Cached or predictive negotiation of compression parameters over a modem relay network connection involves method and apparatus for determining at a gateway the identity of a client/server modem that is called or calling, and using a profile of such called or calling client/server modem, the profile being stored at the gateway or an affiliated agent, to transmit respectively a candidate response or command containing compression parameters. Preferably, a candidate response or command includes an exchange identification (XID) or link request (LR) command or response, either provisioned, i. e. manually configured or automated, i. e. computer-generated. The profile is stored in a memory. The actual achieved parameters for a given call also may be stored, e. g dynamic learning may be had. Finally, establishing such profiles by placing dummy calls once the modem's phone number is known also is described as a feature of the invention.
