Screen
The Maintenance screen (Figure 4-6) allows performing test and maintenance
functions. BERTs are performed by using on-board test facilities. No other test
equipment is needed. Actions initiated by relevant fields are detailed in the
following paragraphs.
Clear Tests
Pressing Enter clears the BERT and any loops that have been initiated.
Clear Alarms
Pressing Enter causes all near-end alarms to be cleared.
T1 Loop
Used to select the test loops initiated. The normal operating mode and available
loopback options are detailed in Figure 4-7 through Figure 4-11.
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.
This does not activate the transmission of the loop code.
Port Loop
Used to loop a high-speed DTE port at the near or far end (see Figure 4-11 and
Table 4-4 on page 49) far-end loops use V.54 loop codes to activate. To enable the
V.54 function, refer to page 60.
