Figure 21.7: ISDN Conﬁguration

‘Start Mode’ deﬁnes how the ISDN interface should be started. ‘OnBoot’

causes the ISDN driver to be initialized each time during the boot process.

‘Manual’ requires you to load the ISDN driver as root with the command

rcisdn start. ‘Hotplug’, used for PCMCIA or USB devices, loads the

driver after the device is plugged in. When ﬁnished with all these settings,

select ‘OK’.

In the next dialog, specify the interface type for your ISDN card and add

ISPs to an existing interface. Interfaces may be either the SyncPPP or the

RawIP type, but most ISP operate in the SyncPPP mode, which is de-

scribed below.

The number to enter for ‘My Phone Number’ varies depending on your

particular setup:

1. ISDN card directly connected to phone outlet

A standard ISDN line provides three phone numbers (called multi-

ple subscriber numbers, or MSNs). If the subscriber asked for more,

there may be up to ten. One of these MSNs must be entered here, but

without your area code. If you enter the wrong number, your phone

operator automatically falls back to the ﬁrst MSN assigned to your

ISDN line.
