Local Control Module - Cisco GS7000 Installation And Operation Manual

Local Control Module

Overview
A local control module and a status monitor are available for the 1.2 GHz SHO
GS7000 Node and Hub Node. A status monitor consists of a local control module
with a transponder core module installed in the housing. The same housing is used
for both units. The units perform the following function:
Local Control Module - controls redundancy and forward segmentation, and

configures the modules
Status Monitor - adds status monitoring capability to the local control module

DOCSIS capability

Status Monitor Description
The status monitor is HMS compliant and provides node monitoring and control
capability at the cable plant's headend. The following node voltages and signals are
monitored and their status reported to the headend by the status monitor.

Receiver optical input level

Transmitter optical output level

AC power presence and peak voltage (for split AC powering cases, AC
power from both sides of node housing is monitored)

DC voltages from both primary and redundant power supplies
Commands are sent from the headend to the status monitor. The status monitor
communicates serially with the RF amplifier module to control the optional forward
band redundancy switches on the forward configuration module, the reverse band 6
dB (wink) attenuators on the reverse amplifier PWB, and the reverse band on/off
switches on the reverse amplifier PWB.
