Forward Configuration Module
2x4 Forward Configuration Modules Description
The 2x4 Forward Configuration Module is used when the 1.2 GHz 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.
The following diagram shows how this module functions.
2x4 Redundant Forward Configuration Modules Description
The 2x4 Redundant Forward Configuration Module is used when the 1.2 GHz
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.
The following diagram shows how this module functions.
