Abstract
A multimedia codec for a frame relay network. Multiple information media from different sight equipment is converted to a standard packet for transmission over said frame relay network. Incoming frames are processed on a priority basis and stored in an elastic buffer. Tests of pointers are kept for each media type identifying the location in the elastic buffer of the various packets for the different media. Applications running in the frame relay processor retrieve the stored media data and forward it to a digital signal processor connected to respective terminal equipment.
