FRX4000 CSU/DSU Tests

Reloading Auxiliary Console Initialization

It should be noted that pinging an FRX interface will verify only connectivity to that
FRX. Using the example in Figure 18-4, if the operator at device A wants to ping
device B, s/he must ping device B's IP address.
To ping Node 1, the operator at device A must ping the IP address of interface 1. To
ping Node B, the operator must ping interface 3. To locate a connectivity problem
between A and B, the operator at device A should first ping interface 1. If a response
is received, the operator at A should then ping interface 3, then (if a response is
received) device B.

To test the CSU/DSU port on an FRX4000, the port must first be disabled. If nec-
essary, press at the Operations Menu (or

To run a CSU/DSU test, press

This operation reloads the terminal settings defined for an async terminal connected
to the Console port on an FRX4000 or the COM1 port on an FRX6000.
