Not used:
A Side Drop Bus Upstream AIS (Unlatched) Alarm Indication -
STS-3 STS-1 No. 3/AU-3 C: A 1 indicates that AIS has been detected
on the A side drop bus in the H1/H2 bytes or in the E13 byte for the
STS-3 STS-1 No.3/STM-1 AU-3 C format. Control bits SE1AIS and
HEAISE (bits 1 and 0, 01DH) determine whether the H1/H2 bytes or the
E13 byte is monitored for AIS detection. This indication is disabled for
the STM-1 VC-4 format.
A Side Drop Bus Upstream AIS (Unlatched) Alarm Indication -
STS-3 STS-1 No. 2/AU-3 B: A 1 indicates that AIS has been detected
on the A side drop bus in the H1/H2 bytes or in the E12 byte for the
STS-3 STS-1 No.2/STM-1 AU-3 B format. Control bits SE1AIS and
HEAISE (bits 1 and 0, 01DH) determine whether the H1/H2 bytes or the
E12 byte is monitored for AIS detection. This indication is disabled for
the STM-1 VC-4 format.
A Side Drop Bus Upstream AIS (Unlatched) Alarm Indication -
STS-3 STS-1 No. 1/AU-3 A, STM-1 VC4: A 1 indicates that AIS has
been detected on the A side drop bus in the H1/H2 bytes or in the E11
byte for the STS-3 STS-1 No.1/STM-1 AU-3 A format or for the STM-1
VC-4 format. Control bits SE1AIS and HEAISE (bits 1 and 0, 01DH)
determine whether the H1/H2 bytes or the E11 byte is monitored for AIS
detection.
A Side Drop Bus Parity (Unlatched) Alarm Indication: A 1 indicates
that an even or odd parity error has been detected in the A side Drop bus
signals. Other than an alarm indication, no action is taken. Parity is mon-
itored for each drop bus clock cycle.
A Side Drop Bus Loss Of Clock Unlatched Alarm Indication: A 1
indicates that the A side Drop bus has detected a loss of clock. An alarm
occurs when the input drop clock is stuck high or low for 56 clock cycles
(DSCLK clock). Recovery occurs on the first clock transition.
