5. Test Menu

The OPTI-3 Controller Module provides access to

multiple loopback tests at the OC-3 and DS3

levels. The following tests are provided:

1. OC-3 Line Loop – Provides a loopback in

the OC-3 interface for data being sent into

the OC-3 interface. During this test, an

Alarm Indication Signal (AIS) is sent all

three DS3 interfaces. See Figure 9.

4. DS3 Local Loop – Provides a loopback

for each individual DS3 coming from the

OC-3 network. Any combination of DS3s

may be tested without affecting any other

DS3. See Figure 12.

loopbacks within the OPTI-3 Controller

Module.

6. Performance Monitoring Menu

command was last asserted. The following

choices are available from the main Performance

Monitoring Menu:

summary registers and displays.

2. Reset Performance Registers

This command initializes all the performance

registers for the OCM.

The OC-3 Section and Line portion of the

Performance Monitoring Menu provides PM

data for the Near and Far Ends. This menu

also allows thresholds to specified and enabled

or disabled. The following submenus are

available:

1. Daily – Provides the user with daily

counts of multiple performance

monitoring statistics including Section
