Programming ISDN BRI Resources
Some steps may not be necessary depending on the service you are providing. For more detailed
programming information, see
“Configuring resources — media bay modules” on page 135 and
“Configuring lines” on page 239 . For complete module installation instructions and safety
precautions, see the Business Communications Manager Installation and Maintenance Guide .
1
Collect the information supplied by your service provider to support your ISDN package. This
includes network service profile identifiers (SPIDs) and Network DNs. If you are supporting a
point-of-sale terminal adapter, you also need one or more static terminal endpoint identifiers
(TEIs).
2
Install the BRIM S/T module in the Business Communications Manager system. (For
information, refer to the
Installation and Maintenance Guides ).
3
Select the module type (BRI-ST). For information on selecting a module type, see “Explaining
the Media Bay Modules headings” on page 136 .
4
Select the type (T or S) for each loop. For information on how to select a loop type, see
“Identifying BRI T-loops (T1 profiles)” on page 279 , “Identifying BRI T-loops (ETSI,
QSIG)” on page 282 , and “Setting BRI for ISDN device connections” on page 289 .
5 Configure the loop type settings:
a
If the module uses a T loop, enter the following configuration information (for North
America only) as supplied by your service provider:
— the SPID assigned to the loop
— the number of B-channels associated with each SPID
— the Network DNs used with the network SPID
— the call type of the Network DN.
Repeat the programming for the second network SPID, if any.
If the T loop is used for D-packet service: turn on the service, assign the appropriate S-loop
mapping and assign the static TEIs (provided by the telco to support a point-of-sale terminal
adapter or other D-packet service device) to the loop.
b If the loop type is S, select the sampling used on the loop. Assign ISDN DNs to the loop
and designate one of the assigned ISDN DNs to be the DN for the loop (Loop DN).
Note: You can have a maximum of 58 ISDN DNs on your system. However, there are
only 28 default DNs provided. The default ISDN DN range is 597 to 694. To add to the
defaults, you need to use DNs from the Companion DN range: 565 to 597 (change DN
type to
ISDN and DECT )
Companion/DECT: If you have either a legacy Companion wireless system, which uses the
Companion range, or a legacy DECT portable system, which uses the ISDN and DECT range,
ensure you do not overwrite any DNs assigned to the handsets for these systems.

Provision the loops and lines. For more information, see “Provisioning lines (PRI, T1,
DASS2)” on page 152 .
