Appendix C ISDN overview 545

Networking Configuration Guide

The NT1 converts and reformats data so it can be transmitted to and from the S or T connection. In

addition, it manages the maintenance messages travelling between the network and the NT1, and

between the NT1 and the BCM system.

The NT1 from Nortel is packaged two ways:

• a stand alone package which contains one NT1 card (NTBX80XX) and a power supply

(NTBX81XX)

• a modular package which contains up to 12 NT1 cards (NTBX83XX) and a power supply

(NTBX86AA)

ISDN standards compatibility

In North America, BCM ISDN equipment supports National ISDN standards for basic call and

calling-line identification services. BCM BRI is compliant with National ISDN-1 and PRI is

compliant with National ISDN-2.

BCM does not support EKTS (Electronic Key Telephone System) on PRI.

In Europe, BCM supports ETSI Euro and ETSI QSIG standards, and PRI SL-1 protocol.

Planning your ISDN network

Consult theBCM50 2.0 Installation and Maintenance Guide (NN40020-302) to determine a

configuration of ISDN trunks and terminal equipment (TE) for the BCM system, and then order

the appropriate ISDN capability package from your ISDN service provider.

For ISDN BRI service, your service provider supplies service profile identifiers (SPIDs), network

directory numbers (Network DNs), terminal endpoint identifiers (TEIs), and other information as

required to program your BCM, TE and other ISDN equipment.

BCM does not support any package with EKTS or CACH. EKTS is a package of features provided

by the service provider and may include features such as Call Forwarding, Link, Three-Way

Calling, and Calling Party Identification.

Ordering ISDN PRI

The following describes how to order ISDN PRI service for your BCM.

Ordering ISDN PRI service in Canada

equipment to the PRI protocol indicated by your service provider.

provider. Set the BCM equipment to the Euro ISDN protocol.
