Control
Module
(SM/LCM)
The local control module monitors the input optical power of
up to four receivers and four transmitters, plus AC power entry
and power supply voltage rails. It also provides local reverse
path wink and shutdown capabilities through the PC-based
GS7000 ViewPort software. It can be upgraded to a status
monitor which provides node monitoring and control capability
at the cable plant's headend. This module is not required for
normal operation of the node. In a hub node application the
SM/LCM also monitors and controls the operation of the
EDFAs and optical switches.

Power Supply
The power supply module has multiple output voltages of
+24.5, +8.5, -6.0, and +5.5 V DC. A second power supply can be
installed in the node for redundancy or load sharing.
The GS7000 Node can be set up in the following powering
configurations:
+24.5, +8.5, -6.0, and +5.5 V DC. A second power supply can be
installed in the node for redundancy or load sharing.
The GS7000 Node can be set up in the following powering
configurations:
two power supplies powered by different AC sources
two power supplies using the same AC source
a single supply using a single AC source

Interface Board
Interface Board
The Optical Interface Board (OIB) provides all interconnections
between the modules in the housing lid of the GS7000 Node.
Each module in the lid plugs directly into the OIB through a
connector header or row of sockets. Input attenuator pads are
provided on the OIB for each optical receiver in the housing lid.
Output attenuator pads are provided on the OIB for each
optical transmitter in the housing lid.
Two Optical Interface Boards are available, a standard
eight-position OIB and an optional six-position OIB which is
primarily used in digital return applications.
