Online/Allow indicates that the OC-3 MUX is Online
and a standby OC-3 MUX can be switched to upon
detection of fault condition.
Online/Inhibit
Online/Inhibit indicates that the OC-3 MUX is online
but inhibited from switching to a standby OC-3 MUX
upon detection of fault condition.
Offline/Allow
Offline/Allow indicates that the OC-3 MUX is offline,
or in standby mode. If the online OC-3 MUX switches
over due to a fault condition, the OC-3 MUX is allowed
to switch back over to the original online OC-3 MUX
upon a subsequent fault condition.
Offline/Inhibit
Offline/Inhibit indicates that the OC-3 MUX is offline,
or in standby mode. The offline OC-3 MUX may
become the online OC-3 MUX due to a fault condition,
but is inhibited from switching back again upon a subse-

Test Menu
Figure 12 represents the OC-3 MUX Test menu. In this
screen, perform various loopback tests at the OC-3, DS3
#1 and #2, and DS1 levels unless the module is in the
“In Service” state, which makes this option unavailable
and read-only. Although it is possible to perform
loopbacks in both the “Out of Service, Maintenance”
and “Out of Service, Unassigned” states, the “Out of
Service, Maintenance” state is recommended.
The loopbacks on this menu are described below:
OC-3 Line Loop
This loopback test loops the data from the network back
toward the network.
OC-3 Local Loop
This loopback test Loops the multiplexed data from the
Access modules back toward the Access modules.
