SNMP interface

Simple Network Management Protocol (SNMP) interfaces with the
traffic-reporting system so that Telephony Manager (TM), or any third-party
system, can have a simple, standards-based interface into the system traffic
reports.
For details about the SNMP interface, see Communication Server 1000
Fault Management – SNMP (NN43001-719).

Heterogeneous environments

In a heterogeneous environment, with a mixture of Nortel equipment and
third-party equipment, voice-quality monitoring, detection, and alarming
are performed only on IP endpoints that have voice-quality monitoring
capabilities.
For information about IP endpoints and their voice-quality capabilities in the
system, see
