Ordering ISDN BRI service in Canada
In Canada, order Microlink™ service, the trade name for standard BRI service. You can order
either regular Microlink™ service, which includes the CLID feature, or Centrex Microlink™,
which includes access to additional ISDN network features, including Call Forwarding.
When ordering Microlink™ service, it must be ordered with EKTS turned off. If you will be using
a point-of-sale terminal adapter (POSTA), ask for D-packet service to be enabled.
Ordering ISDN BRI service in the United States
In the United States, regardless of the CO (Central Office) type, order National ISDN BRI-NI-2
with EKTS (Electronic Key Telephone System) turned off. Use the following packages as a
guideline for ordering your National ISDN BRI-NI-2. However, we recommend using packages
M or P with the BCM system. Contact your service provider for more information about the
capability packages it offers. Bellcore/National ISDN Users Forum (NIUF ISDN packages
supported by BCM (for ordering in U.S.).
If you want to transmit both voice and data, and support D-channel packet service, order
package P. However, BCM 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. BCM 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 or the United States
Outside of Canada or the United States order Euro ISDN PRI and/or BRI service from your service
provider. Set the BCM equipment to the Euro ISDN protocol.
