Hardware Description
Tenor CMS is available in CMS (14 slot), CMS960 (8 slot), and a CMS240 (2 slot).
The CMS (14 slot), CMS960 (8 slot), and CMS240 (2 slot) provide network connection and functionality
through WAN cards, DSP resource cards, and a system controller card/CPU card. Communication through the
chassis backplane is achieved through the following: packet bus and TDM bus. The packet bus is used for car-
rying packet-oriented data and the TDM bus is used for transporting circuit switched PCM traffic.
For the AC unit, the front side of the chassis provides access to WAN cards (T1/E1/DS1), power supplies, the
system controller card/CPU card, and DSP card; the rear side exposes the back portion of the transition cards
for network connection as well as power cord connection.
For the DC unit, the front side of the chassis provides access to WAN cards (T1/E1/DS1), DSP cards, the sys-
tem controller/CPU card and power supplies. The rear side exposes the back portion of the transition cards for
network connections, as well as the circuit breakers, power receptacles and power plugs.
Through all of these units, you can connect up to four different points: Line Circuit (PBX), Trunk Circuit
(PSTN), Data network (Ethernet LAN) and a PC.
