Maintenance Screen The Element Maintenance screen (Figure 4-4) allows performing loop tests and/or
BERT functions on the DDS circuit. This screen also allows activating and
clearing loops and the BERT tester. BERT is performed by using on-board test
facilities. No other test equipment is needed. Some of these tests may also be
activated by the front panel switch as described in chapter Operation.
Clear Tests
Pressing Enter on this field clears all local tests and any line loops that have been
initiated.
Clear Alarms
Pressing Enter on this field causes all near end alarms to be cleared.
Loop
The type of loop is chosen by toggling the spacebar and is executed by pressing
Enter. Options include LOCAL, V.54, and FAR V.54. Local and V.54 generate
near-end loops. Far V.54 generates a V.54 loop at the far end.
A FAR V.54 loop started from the front panel switch cannot be unlooped from the
Maintenance screen. It must be unlooped from the front panel switch.
Unloop
Pressing Enter takes down the specified loop from the selected port. The type of
loop is chosen by toggling the spacebar and is executed by pressing Enter. Options
include LOCAL, V.54, and FAR V.54.
