signaling channel (D-channel) to conduct low-bandwidth operations.
Async-Sync PPP Conversion
Asynchronous to synchronous PPP conversion. Converts asynchronous
PPP into synchronous (HDLC-based) PPP that can be transported in
ISDN B-channels to communications servers that have integrated ISDN

B-channel
Bearer channel. In ISDN communications, a B-channel transmits data
and voice traffic at a rate of up to 64 Kbps.
BRI
Basic Rate Interface. One of two access methods to the ISDN. Each
BRI consists of two 64 Kbps B-channels and one 16 Kbps D-channel
for each ISDN line.
Call Drop
A supplementary voice feature that allows you to remove the last caller
