Table 3-20. ISDN BRI DBM Physical Interface Options (9126, 9626)

Interface Status

Possible Settings: Enable, Disable

Default Setting: Disable

Determines whether the ISDN interface is available for use.

Enable – The ISDN interface is enabled.

Disable – The ISDN interface cannot be configured, nor can it transmit or receive data. No PVC connections or frame relay DLCIs will be deleted. Disabling the ISDN interface results in the following:

￿All currently connected ISDN calls are terminated.

Alarms or traps associated with this interface are not generated or displayed.

Service Profile ID (SPID) 1 or 2

Possible Settings: 3 – 20 digits

Default Setting: Clear

Specifies the SPID number assigned by the ISDN service provider for Bearer channel 1 (B1) and Bearer channel 2 (B2). SPID numbers are used by the switch to identify which ISDN services the DBM can access. All blanks is a valid setting.

3 – 20 digits – You can enter a SPID number, or you can leave blanks. If a nondigit/ numeric is entered, an Invalid Character (x) message appears at the bottom of the screen. If fewer than three digits/numerics are entered, an Invalid – SPID must be at least 3 digits message appears at the bottom of the screen.

Clear – Clears the SPID field so it can be reentered.

Local Phone Number 1 or 2

Possible Settings: 10 digits

Default Setting: Clear

Provides the telephone number associated with Bearer channel 1 (B1) and 2 (B2). All blanks is a valid setting.

10 digits – Enter the telephone number, up to 10 digits. If a nondigit/numeric is entered, an Invalid Character (x) message appears at the bottom of the screen.
