System Integration
The SBC implements the four-wire S and T interfaces used in the ISDN basic access. It may be
used at both ends of these interfaces.
The applications include:
ISDN terminals (TE)
ISDN network termination (NT)
ISDN subscriber line termination (LT-S)
ISDN trunk line termination (LT-T) (PABX connection to Central Office).
These applications are shown in
figure 1
, where the usual nomenclature as defined by the CCITT
for the basic access functional blocks and reference points, has been used.
