BRI Maintenance

Maintenance for the Basic Rate Interface (BRI) focuses on the functioning of the
800 CO-BRI module. Because the MERLIN LEGEND system is using those BRI
features offered by the central office (CO), the system maintenance is the
responsibility of the CO. Still, there are automatic and demand tests that check
the functioning of the module, logs in which errors are recorded, error
messages that tell the user when errors occur, and alarms that also alert the
user to errors.
Maintenance for the BRI is similar to maintenance for other modules: the status
of the module can be viewed on the Slot Status screen, and additional
information about the module is displayed by the System Inventory screen. Like
other modules, the 800 CO-BRI module must be "busied-out" or reset before
demand tests or replacement can be done. (See the Installation, Programming,
and Maintenance manual, 555-620-140, for more information on basic
maintenance procedures.)
The demand tests associated with BRI maintenance are:
Internal (DSE) Loopback test (located on the Demand Test menu)
Board Controller test (located on the Demand Test menu)
B-Channel Loopback test (located on the Slot menu)
In addition, users can check the following information:
Clock status of the 800 CO-BRI module
Digital Subscriber Line (DSL) error events
