ISDN Menu/SPID
The service profile identifier (SPID) is a sequence of digits
used to identify ISDN terminal equipment to the ISDN
switch. The SPID is assigned by the local phone company
when the ISDN line is installed; the SPID looks like the phone
number. Obtain SPIDs from the telephone administrator or
local telephone representative.
The number of SPIDs required (up to eight) depends on how
the ISDN line is configured. For instance, there are no SPIDs
for a point-to-point line. Multipoint lines may have one or two
SPIDs. The ISU 512e uses the presence of SPID 1 to determine
whether the line is multipoint. If the line has only one SPID,
then it must be entered in SPID 1, SPID 3, SPID 5, and SPID 7,
depending on the number of lines being installed.
Since several of the SPIDs may have a similar format,
using the copy and paste functions provided by the
terminal menu interface may prove convenient.
SPID numbers correspond to the IFC connector on the rear of
the ISU 512e as follows:
IFC #1 SPID 1 (pair with LDN 1) and SPID 2 (pair with LDN 2)
IFC #2 SPID 3 (pair with LDN 3) and SPID 4 (pair with LDN 4)
IFC #3 SPID 5 (pair with LDN 5) and SPID 6 (pair with LDN 6)
IFC #4 SPID 7 (pair with LDN 7) and SPID 8 (pair with LDN 8)
From the front panel, use the up and down arrows to select
the SPID to enter. Press
keypad to enter the SPID number. While keying/editing a
SPID, the down arrow allows backspacing through the num-
ber string to correct mistakes. The up arrow scrolls back to the
last digit entered. To cancel a number, use the down arrow to
backspace through the number; then press
ing each SPID, press
