ABSTRACT:
A system and method are disclosed for adapting the rate of a data terminal equipment having a V-series type interface connected to an integrated services digital network which supports more than two simultaneous communications. A V.110 rate adapter is provided which receives user data at a user data rate from the data terminal equipment and outputs a bitstream containing the user data at a B-channel data rate. A fractional rate adapter is also provided which receives this bitstream and outputs a second bitstream at a lower subchannel data rate using a bit discarding technique.
