2x2 and 2x4 Forward Configuration Modules Description
The 2x2 or 2x4 Forward Configuration Module is used when the GS7000 Node is
configured with two optical receivers, each feeding two 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: The 2x2 FCM can only be used with the 2-way RF amplifier module. The 2x4
FCM can only be used with the 4-way RF amplifier module.
The following diagram shows how this module functions.

2x2 and 2x4 Redundant Forward Configuration Modules Description
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 RF
outputs of the amplifier module in a redundant configuration. In this configuration,
the node serving area is divided in half for 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 digital signal from the status monitor/local
control module.
Note: The 2x2 Redundant FCM can only be used with the 2-way RF amplifier
module. The 2x4 Redundant FCM can only be used with the 4-way RF amplifier
module.
