The data protocol, also known as the B-channel protocol and
the rate adaption protocol, is the “language” that is spoken over
each 64K bps channel between two ISDN devices. The devices
on both ends of the ISDN link must use identical data protocols.
MLPPP Protocol
The MLPPP (Multi-Link PPP) protocol provides rates up to 64K
bps per channel. This protocol uses both B channels at once,
providing an aggregate data transmission speed of 128K bps.
