Operational Description
The ISAC-S, designed for the connection of subscribers to an ISDN using a standard S/T
interface, has the following applications, corresponding to the operating modes explained in
chapter 2:
Terminal Equipment TE1, TA
→ TE mode
e.g. ISDN feature telephone,
ISDN voice/data workstation
Terminal Adapter for non-ISDN terminals (TE2)
Network termination NT2
e.g. PABX, including the following functions:
Line termination on S
such as an IPBX S interface line card
→ LT-S mode
→ LT-T mode
→ NT mode
Line termination on T
to connect an NT2 to an NT1 (digital trunk module)
Intelligent Network Termination
e.g. NT1 with maintenance functions
The operating mode of the ISAC-S must be set via pin strapping (pins M1, M0), as described
in section 2.2, before a hardware reset.
