Yellow Alarm
A yellow alarm may be generated on the trans-
mit side by pulling TYEL high. In 193S mode,
bit 2 yellow alarms are supported internally. In
193E mode, FDL yellow alarms are supported.
These formats are also detected by the receiver
and reported on RYEL. Blue alarms are not sup-
ported in hardware mode, except for the
transmission of all "1’s" on TPOS/TNEG during
loopback.
If S-bit yellow alarm is desired while in 193S
mode, it may be externally provided via S-bit in-
sertion, enabled by pulling the 193SI pin high.
There is, however, no way to generate a bit 2
yellow alarm while in 193E mode. Moreover, the
device will not decode either of these formats,
while in hardware mode. If they are required, ex-
ternal alarm detection must be provided.
Zero Suppression
B7 selects the B7 zero suppres-
sion format for the transmitter. Pulling the B7
pin high enables bit 7 stuffing. Pulling the B8ZS
pin high enables B8ZS encoding on the transmit-
ter. The receiver is always capable of decoding
either B8ZS or AMI-encoded data. Transparent
mode may be selected by holding both pins low.
Loopback
Loopback is also provided in the hardware mode
by simultaneously driving the B7 and B8ZS pins
high. The previous state of the pins is main-
tained, and the selected zero suppression mode
remains effective during loopback. While in
loopback, an unframed all "1’s" signal (Blue
alarm) is output on TPOS/TNEG.
