Main Hardware Components
The C4c CMTS base system contains the following components:
C4c CMTS chassis
One or two Power Modules (PMs) – Power Feeds A & B
Cable Access Modules (CAMs) and associated Physical Interface Cards (PICs)
Router Control Module (RCM)
System Control Module and associated PIC
One Fan Tray Module containing six fans
Air filter (factory installed)
Chassis Configuration
There are various ways to equip a chassis. CAM configurations are dependent on the configuration of the cable plant of the
subscriber network. The module faceplate in each slot includes a label stating the module type and multiple LEDs to
indicate the module’s status.
Design of the C4c CMTS
The C4c CMTS operates in simplex mode. It does not support Control Complex Redundancy (CCR). A fully equipped C4c
CMTS can support up to 10,000 customer premise devices.
This chassis is equipped with dual redundant power supplies. These can be either AC or DC, or one of each. The chassis can
continue to operate if one of the two power supplies fails. There is one Fan Tray Module which contains six fans and the air
filter.
The client and system modules1 of the C4c CMTS are the same modules that are used by the C4c CMTS. The system and
client modules, the Fan Tray Module, and the Power Modules are all field replaceable.
A fully loaded C4c CMTS is equipped with a total of eight modules, two power modules, and a fan tray module:
One (1) System Control Module (SCM)
