6.4 Multiple Modem Configuration

The multiple Modem configuration consists of a master Modem and up to five (5) slave
modems (See Figure 6-10) linked together to increase the data throughput available at
a node. This is also referred to as Modem Stacking or the Stack configuration.

This section explains how to configure a Modem Stack. Modems in a stack also require
extra  cabling  to  connect  their  frame  strobes,  IF  (RX/TX)  distribution,  frequency
reference  and  an  Ethernet  switch  to  combine  the  CDU  ports.  For  more  information  to
connecting the stack on the rear of the Modem, refer to section 14.2 Modem  Stacking
Installation

NOTE

The IP addresses are for illustration purposes only. These settings
are user defined.
