6.2.3.3.1 Remote Access By ISDN Modem

ISDN Modem Recommended
Alcatel-Lucent OmniPCX Office Communication Server is equipped with a 64K (1
B-channel)/128K (2 B-channels) ISDN modem using PPP protocol for remote access through
the public network. It provides a point-to-point link accessible via standard LINUX procedures
(PPP, etc.).
For a 64K (1 B-channel) connection, the following modems are validated:
- KORTEX NOVAFAX ISDN 128000/33600 with PPP protocol
- FRITZ ¡X CAPI 2.0 or any standard "FRITZ" modem
- Multitech I Way Hopper MTA 128 ST 128 KBPS ISDN (see note below)
For a 128K (2 B-channels) connection, the following modems are validated:
- OLITEC USB ISDN 128K
- Multitech MTA128ST-RC ML-PPP (see note below)
- Eicon Diva 852 ISDN T/A USB - ISDN BRI ST - 128 Kbits/s
ISDN 64 to 128 KPBS modems handling the PPP protocol are generally compatible and
support CHAP authentication.
Note:
When using the Multitech modem, the authentication method must be set to CHAP. This is the default
method for current firmware versions. For modems with older firmware, you must either update the firm-
ware or activate CHAP with the AT command AT S58=3.
RAS Installation Process
In Windows 2000/XP/Vista, you do not need to install new operating system components
before configuring a new access method; the Remote Access Services (RAS) component is
installed by default on these systems.
The sub-sections below describe how to set up the following remote access methods:
- Direct V24 Connection (OmniPCX Office Direct V24)
- Remote connection via ISDN modem (an example is provided for driver installation)
