Programming Operations Guide
Ordering ISDN BRI Service in the United States
In the U.S., regardless of the CO (Central Office) type, order National ISDN BRI-NI-1 with EKTS
(Electronic Key Telephone System) turned off. Use the following packages as a guideline for
ordering your National ISDN BRI-NI-1. However, we recommend using packages M or P with the
Business Communications Manager system. Contact your service provider for more information
about the capability packages it offers. Bellcore/National ISDN Users Forum (NIUF ISDN
packages supported by Business Communications Manager (for ordering in U.S.).
If you want to transmit both voice and data, and support D-channel packet service, order package
P. However, Business Communications Manager does not support the flexible calling for voice
and additional call offering features that are included in package P.
Multi-Line Hunt may be ordered with your package. When a telephone number (the Network DN)
in the group of numbers assigned by your service providers is busy, the Multi-Line Hunt feature
connects the call to another telephone number in the group. Business Communications Manager
supports the feature only on point-to-point, network connections (T loop). Check with your service
provider for more information about Multi-Line Hunt.
Any of the ISDN packages will allow you to use sub-addressing, but your ISDN TE must be
equipped to use sub-addressing for the feature to work.
Ordering ISDN BRI Service Outside Canada and the United States
Outside of Canada or the United States order Euro ISDN PRI and/or BRI service from your service
provider. Set the Business Communications Manager equipment to the Euro ISDN protocol.
Supported ISDN Protocols
The switch used by your service provider must be running the appropriate protocol software and
the correct version of that software to support ISDN PRI and BRI. Each protocol is different and
supports different services. Contact your service provider to make sure that your ISDN connection
has the protocol you require.
For more information on the supported protocols and services, refer to “Provisioning for Call by
Call limits with PRI” on page 352 .
