Maintenance
Screen The Element Maintenance screen (Figure 4-6) allows performing loop-test and
BERT functions on the T1 circuit. Loops can be activated and cleared and the
BERTs performed. A 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 push buttons as described in Controls and Indicators on page 3-1.
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.
T1 Loop The type of T1 loop is chosen by toggling the spacebar and is executed by
pressing Enter. This unit supports payload loopbacks, line loopbacks, maintenance
loopbacks for both the near and far ends of the network and DTE interfaces.
Loop status changes can be made only when the BERT function is not in the active mode.
