ISDN S-INTERFACE
DEFINITION
A S-interface offers the possibility to connect ISDN
terminals on the user side.
Terms:
ISDN Integrated Services Digital Network
S S-reference point, user side
(= 2B+D user interface
= S - interface )
T T-reference point, network side
( = 2B+D network interface
or 30B+D network interface
= T - interface )
TE Terminal Equipment
e.g. Telefax G4
PC with ISDN board
PC with ISDN board and telephone
Terminal adapter
Videophone
ISDN telephone
As regards ISDN-telephones, only basic functions
concerning voice communication are supported.
Therefore, we recommend to continue to use the
proprietary digital system telephones (DIALOG 3000).
USE
ISDN-terminals that are in compliance with the
ACA ( = Australian Communication Authority),
ETSI ( = European Telecommunications Standards
Institute) recommendations (EURO - ISDN) and also
country specific versions of the ETSI standard are
supported on the S-interface:
• ISDN Telefax G4
• ISDN PC cards
• ISDN LAN cards
• ISDN Terminal adapter
• ISDN Videophones
• ISDN telephone
• ISDN Personal Conferencing Video
Systems ( e.g. Intel Proshare )
The main purpose/application is to support data and
video transmission in temporary "dial-up" connections
using the public ISDN capabilities.
It is NOT intended for in-house PC networks.
For this purpose, a PC-LAN meets the requirements
( data rates far higher than 64kbps as provided on an
ISDN - B channel ) much better than an ISDN-
connection via a PBX.
