Configuring a BRAFS ISDN set with SPID
The Service Profile Identifier (SPID) is a number which associates a termi-
nal to its subscribed services. A SPID must be datafilled in the physical
terminal for Layer 3 ISDN connectivity. For National ISDN-1 (NI-1), a
2-digit user-definable number terminal ID (TID) must be included in the
SPID configuration. The TID is not datafilled in the DMS-100.
Protocol Version Control 1 SPID = NPA + 7-digit DN + spid-suffix (if
datafilled in the switch)
Protocol Version Control 2 SPID = NPA + 7-digit DN + spid-suffix (if
datafilled in the switch) + TID
spid-suffix
= one to two digit identifier for EKTS-based services, e.g.
MADN; MUST match spid-suffix datafilled in the switch.
Note: A spid-suffix is not required for non-EKTS ISDN sets.
Reserving a Spare DCH
Nortel recommends reserving one D-channel handler (DCH) per XPM as a
hot spare. For example if you have two DCHs in table DCHINV, only
datafill one ISG in table ISGDEF. The second DCH becomes a hot spare.

Note: Bd (D-channel packet service) channels start at DCH port 31 and are
datafilled backwards: 31, 30, 29, etc. BRA channels are datafilled
from DCH port 1 forward.

Loopback testing can be done at one of 4 places:
T Interface:
Loopback at T interface of the NT1 towards the DMS.
LU Interface: Network side of line card.
MPLU Interface: Loop extenders between the ISLC and the NT.
L Interface:
CC side of line card.
Loopback points can be set at the LTPDATA level using the LOOPBK
command and B1 (b-channel 1), B2 (b-channel 2), or BBD (all channels).
