Maintenance
Screen The Maintenance screen (Figure 4-6) allows performing test and maintenance
functions on the T1 circuit. BERT is performed by using on -board test facilities.
No other test equipment is needed. Actions initiated by each field are detailed in
the following paragraphs.
Clear Tests Pressing Enter on this field clears all tests and any line loops that have been
initiated.
Clear Alarms Pressing Enter on this field causes all near-end alarms to be cleared.
Test Loops Loop status changes can be made only when the BERT function is not in the active
mode. The type of loop is chosen by toggling the spacebar and is executed by
pressing Enter.
T1 Loop
Used to select the test loops initiated. The normal operating mode and available
loopback options are detailed in Figure 4-6.
T1 Unloop
Pressing Enter on this field takes down the specified loop.
FAR LLB
This switch allows selecting how in-band line loopback code is transmitted: framed
or unframed per ANSI T1.403.
