ISDN Dial Backup

If a clear channel 64 kbps circuit is required to back up the DDS circuit,
placing #4 at the end of the smart dial string (phone number entered into
Stored Number 1-8) causes the ISDN DBU mode to establish the backup
connection at 64 kbps instead of 56 kbps. For example: 2059718000#4.

Setting the Service Profile Identifier (SPID)

For ISDN dial backup, the service profile identifier (SPID) must be entered
in Stored Number 9. The SPID is a sequence of digits used to identify
ISDN terminal equipment to the ISDN switch when more than one ISDN
set has been attached to the same central office line. The SPID is assigned
by the telco when the ISDN line is installed and normally resembles the
phone number.
Generally, the 5ESS custom switch is configured for a point-to-point net-
work and a SPID is not required. SPID is required for 5ESS or Northern
Telecom switches with ISDN National 1 interface.
