6.2.3.4.1 Remote Access By ISDN Modem
6.2.3.4.1.1 ISDN Modem Recommended
OXO Connect 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 firmware or activate CHAP
with the AT command AT S58=3.
