Chapter 1: Overview
If the network conditions for an IP call become unacceptable—according to the delay and packet loss specifi-
cations you configure—Tenor CMS will switch the call to the PSTN automatically and transparently. The
Tenor CMS continuously monitors your data network for jitter, latency and packet loss, and transparently
switches customer calls to the PSTN when required.
Dynamic Call Routing
Tenor CMS’s intelligent call routing capabilities are state-of-the-art. The chassis automatically detects and
supports two call types: voice and fax.
Tenor CMS will first identify the call origination site —trunk circuit, line circuit, or IP routing group —and
then route the call according to any parameters you configure in the routing database. Each call may be routed
via circuit switched path between any two circuit groups, or compressed and transported via VoIP when con-
necting to an IP routing group. Trunk circuits are those that typically connect to another circuit switched net-
work such as the PSTN. Line circuits typically connect to a termination device on the user premises, such as a
PBX.
Multiple Channels/Signaling Supported
Any combination of DS1, or T1 and E1 cards (up to 4) may be used to achieve up to 960 channels. The Tenor
CMS provides support for most Channel Associated Signaling (CAS) and ISDN protocols.
Fractional T1/E1 Support
Tenor CMS supports Fractional T1/E1.
