The S-Interface is the standardized four wire digital telephone
access point defined by the CCITT I-Series recommendations
for the Integrated Service Digital Network. This “basic rate
access” accommodates two 64 Kbps “B-channels” for infor-
mation, one 16 Kbps “D-channel” intended for signaling and
