Alarm Management - Nortel Meridian M1250 Description

• Direct Inward System Access (DISA) through the CCBA prompt
• Tandem calls dialed with Coordinated Dialing Plan (CDP) (Trunk
Steering Code, Distant Steering Code) through the CCBA prompt
• Tandem non-CDP calls through the CCBA prompt in the Route Data
Block from the outgoing trunk route
When a call is answered by a CCB user, the Meridian 1 sends the CCB
answer signal in place of the regular signal for incoming DID/CO calls from
the routes with CCB enabled. If the call is a collect call, The CO will
disconnect the call.

Alarm Management

The Integrated Alarm Management feature is a series of subfeatures which
improve the handling of key alarm messages generated by the Meridian 1
system and its Application Processors.
It also clarifies existing alarm messages and makes Attendant Console alarm
lamp signals more meaningful. The Meridian 1 system has three levels of
alarm: critical, major, and minor. The Attendant Console alarm lamp will
light when critical alarms occur.
Digital Trunk Interface – CIS
The CIS DTI trunk feature provides connectivity between the Meridian 1 and
digital trunks used in the Commonwealth of Independent States (CIS).
The CIS 2Mbps DTI feature is designed to allow the Meridian 1 to connect
digital DID/COT trunks to a CIS Local Central Office and to a CIS Toll
Exchange (through Local CO and Public Network, or directly for incoming
toll call connections). This link supports DID/COT trunking types, and
requires that the Meridian 1 be equipped with at least one CDTI2/CSDTI2
digital trunks pack, as well as associated software.
