PABX Number (with S/T Bus Number) for Loopback
Enter the S/T bus number if the router is connected to an ISDN PABX. If this field is left as blank then the ISDN loopback test will be skipped.
Outgoing Calling Party Number
If these fields are not blank, the router will use these values as the calling party number for "ISDN Data", "A/B Adapter 1" and "A/B Adapter 2" outgoing calls. Otherwise, the individual entries for "ISDN Data", "A/B Adapter 1" and "A/B Adapter 2" will be used as the calling party number. You only need to fill in these fields if your switch or PABX requires a specific calling party number for outgoing calls, otherwise, leave them blank.
The following diagram illustrates the PABX Number (with S/T Bus Number) for Loopback and Outgoing Calling Party Number fields for a router behind an ISDN PABX.
