The 1x2 and 1x4 Redundant Forward Configuration Modules
with forward RF injection are similar to the 1x2 and 1x4
Redundant Forward Configuration Modules, but are used with
the Forward Local Injection (FLI) Module. The FLI Module
routes an RF signal from an external source to the Forward
Configuration Module which is then coupled with other inputs
from an optical receiver. (Note that the 1x2 Redundant FCM
with forward RF injection can only be used with the 2-way RF
amplifier module and the 1x4 Redundant FCM with forward RF
injection can only be used with the 4-way RF amplifier module.)
The 2x2 or 2x4 Forward Configuration Module is used when the
GS7000 Node is configured with two optical receivers, each
feeding two/three outputs of the amplifier module. In this
configuration, the node serving area is divided in half in the
forward direction. Receiver 1 is routed to RF amplifier Ports 4
and 5/6, while Receiver 3 is routed to RF amplifier Ports 1 and
2/3. (Note that the 2x2 FCM can only be used with the 2-way
RF amplifier module and the 2x4 FCM can only be used with
the 4-way RF amplifier module.)
The 2x2 or 2x4 Redundant Forward Configuration Module is
used when the GS7000 Node is configured with four optical
receivers with each pair feeding two/three RF outputs of the
amplifier module in a redundant configuration. In this
configuration, the node serving area is divided in half, with
redundancy, in the forward direction. Receivers 1 (primary) and
2 (redundant) are routed to RF amplifier Ports 4 and 5/6, while
Receivers 3 (primary) and 4 (redundant) are routed to RF
amplifier Ports 1 and 2/3. The active receiver is selected with a
status monitor or local control monitor. (Note that the 2x2
Redundant FCM can only be used with the 2-way RF amplifier
module and the 2x4 Redundant FCM can only be used with the
4-way RF amplifier module.)
A 3x4 Forward Configuration Module is used when the GS7000
Node is configured with three receivers each feeding
one/two/three/four outputs of the amplifier module. Two
versions of this module are available. In one version Receiver 1
is routed to RF amplifier ports 4/5/6, Receiver 3 is routed to
port 1, and Receiver 4 is routed to ports 2/3. In the other
version Receiver 1 is routed to RF amplifier ports 5/6, Receiver
2 is routed to port 4, and Receiver 4 is routed to ports 1/2/3.
(Note that the 3x4 FCM can only be used with the 4-way RF
amplifier module.)
The 4x4 Forward Configuration Module is used when the
GS7000 Node is configured with four optical receivers with
each feeding separate RF outputs of the amplifier module.
Receiver 1 is routed to RF amplifier Ports 5/6. Receiver 2 is
routed to RF amplifier Port 4. Receiver 3 is routed to RF
amplifier Port 1. Receiver 4 is routed to RF amplifier Ports 2/3.
(Note that the 4x4 FCM can only be used with the 4-way RF
amplifier module.)

The 2x2 or 2x4 Redundant Forward Configuration Module is
used when the GS7000 Node is configured with four optical
receivers with each pair feeding two/three RF outputs of the
amplifier module in a redundant configuration. In this
configuration, the node serving area is divided in half, with
redundancy, in the forward direction. Receivers 1 (primary) and
2 (redundant) are routed to RF amplifier Ports 4 and 5/6, while
Receivers 3 (primary) and 4 (redundant) are routed to RF
