substitution of the incoming data stream.
When in LINE BERT mode, only the DATA MODE option for the T1
under test may be selected. Selecting any other option will result in an er-
ror message being displayed.
Only one T1 port may engage a CSU LOOPBACK, CSU LOOPBACK
w/BERT, or a LINE BERT. If a CSU LOOPBACK, CSU LOOP-
BACK w/BERT, or a LINE BERT is already active at the time a new
CSU LOOPBACK, CSU LOOPBACK w/BERT, or LINE BERT is se-
lected, the former test will be terminated and the latter test will be en-
gaged.
