CPU Card (Available for CMS P2.x.x)
The CPU card is a single slot Compact PCI (Peripheral Component Interconnect) controller card which pro-
vides the central management functionality for the Tenor CMS unit. The controller card is the call routing
engine for the system and coordinates all activity within the chassis, including system resource management/
monitoring. The CPU card provides an interface for transferring VoIP data throughout the system and commu-
nicating with the other network cards via PCI bus.
As the central point of system resource management, the CPU card implements the intelligent call routing and
IP call signaling. The card also acts as an interface through which the user is able to perform network and sys-
tem management functions.
When CPU card is inserted in the slot, it connects to an associated Rear Transition Module (RTM) in the rear
of chassis.
NOTE: For the purposes of this document, the term “CPU” card indicates the CPU application card and
transition module as a single unit.
Through the CPU card, you are able to perform system functions, such as resetting the system, connect to an
Ethernet hub/switch, or connect to a PC. In addition, LEDs provide a high level indication of system and chas-
sis activity.
NOTE: All Input/Output ports and connections for the CPU card are located on the rear panel of the card.
For the CMS (14 slot), the CPU card is always inserted in slot 14 — the slot nearest the power supplies with a
red card guide—when viewing from the front of the chassis. For CMS960 (8slot), and the CMS240 (slot), the
CPU card is always inserted in slot 1, the bottom slot.
