Making Monitor Connections
to monitor signals for both routers through the primary router’s connection to the monitoring equip-
ment. For simplicity, this procedure refers to each router as the
primary or secondary router.
Monitor expansion connections are created by connecting the ‘OUT’ monitor connections on the
secondary router to the ‘IN’ monitor connections on the primary router.
How to Make Monitor Expansion Connections
1 Locate the monitor connections on the rear of the router, as shown in Figure 3-14 on page 44.
2 On the secondary router (the router that does not have direct connections to the monitoring
equipment), connect to the ‘OUT 1’ monitor connection using a 75
Ω
BNC connector and coax-
ial cable.
3 Connect the other end of the cable to the ‘IN 1’ monitor connection on the primary router using
a 75
Ω
BNC connector (the router with direct connections to the monitoring equipment), as
shown in Figure 3-15.

4 On the secondary router, connect to the ‘OUT 2’ monitor connection using a 75
Ω
BNC con-
nector and coaxial cable.
5 Connect the other end of the cable to the ‘IN 2’ monitor connection on the primary router using
a 75
Ω
BNC connector, as shown in Figure 3-15.
Note
Unused ‘IN’ connections on the secondary router do not need to be terminated with
a BNC terminator.
