About this document

This document is a global document. Contact your system supplier or your

Nortel representative to verify that the hardware and software described

are supported in your area.

Subject This document describes ISDN Basic Rate Interface (BRI) maintenance

tools and procedures to assist in identifying faults, locating defective units,

correcting problems by ﬁxing or replacing defective units, and verifying

operation after the corrections or replacements have been made.

This document focuses on the maintenance of ISDN BRI equipment installed

in Meridian 1 and CS 1000M systems, and requires that non-ISDN BRI

functions operate correctly before starting to diagnose ISDN BRI problems.

Please note the following:

•ISDN BRI trunking is not supported in North America.

•The Basic Rate Signaling Concentrator (BRSC) is not supported on

Small Systems and CS 1000S systems.

•The integrated Meridian 1 Packet Handler (MPH) is not supported on

Small Systems and CS 1000S systems.

•Communication Server 1000E (CS 1000E)

Note: When upgrading software, memory upgrades may be required on

the Signaling Server, the Call Server, or both.

System migration

When particular Meridian 1 systems are upgraded to run CS 1000 Release

4.5 software and conﬁgured to include a Signaling Server, they become

CS 1000M systems. Table 1 "Meridian 1 systems to CS 1000M systems"

(page 8) lists each Meridian 1 system that supports an upgrade path to

a CS 1000M system.
