4x3-1,3,4 Reverse Configuration Module with Auxiliary Reverse RF
Injection Description
Injection Description
The 4x3-1,3,4 Reverse Configuration Module with auxiliary reverse RF injection
combines reverse inputs from Ports 1 and 2/3 and routes them to Transmitter 1; it
also routes reverse inputs from Port 4 to Transmitter 3 and from Ports 5/6 to
Transmitter 4. An RF signal from an external source can optionally be injected at
Ports 3/6 and coupled with the reverse RF inputs from Ports 2/3 and 1 and routed
to Transmitter 1.
The following diagram shows how this module functions.

4x4 Reverse Configuration Module with Auxiliary Reverse RF Injection
Description
Description
The 4x4 Reverse Configuration Module with auxiliary reverse RF injection routes
reverse inputs from Port 1 to Transmitter 1, from Port 2/3 to Transmitter 2, from
Port 4 to Transmitter 3, and from Port 5/6 to Transmitter 4. An RF signal from an
external source can optionally be injected and coupled with reverse RF inputs from
Ports 3/6 and routed to Transmitter 1.
Note: This module is typically installed when using bdr multiplexing digital reverse
modules. Since the digital reverse module occupies the physical space that
transmitters 3 and 4 normally occupy in the node base, this reverse configuration
module is typically used with a 6-port optical interface board.
The following diagram shows how this module functions.
