ERDIV[2:0]:
The ERDIV[2:0] bits indicates the extended remote defect indication status of
tributary TU #1 in the corresponding TUG2 when RDIZ7EN is set high. The
ERDIV[2:0] bits are set to a new code when the same code in the extended
RDI bits of the Z7 byte is seen for five or ten consecutive multiframes as
determined by the RDI10 bit in the RTOP and RTTB Configuration registers
(addresses 0CH, 0DH, and 0EH).
PSLMV:
The PSLMV bit indicates the path signal mismatch status of tributary TU #1 in
the corresponding TUG2. PSLMV is set high when the accepted PSL differs
from the provisioned value. PSLMV is set low when the accepted PSL has
the same value as the provisioned one.
PSLUV:
The PSLUV bit indicates the path signal unstable status of tributary TU #1 in
the corresponding TUG2. The PSL unstable counter is incremented if the
PSL of the current multiframe differs form that in the previous multiframe. The
counter is cleared to zero when the same PSL is received for five consecutive
multiframes. The tributary PSL unstable alarm is asserted and PSLUV set
high when the unstable counter reaches five. The PSL unstable alarm is
negated and PSLUV set low when the unstable counter is cleared.
PDIVEN:
The PDIVEN bit modifies the payload defect indication status PDIV of
tributary TU #1 in the corresponding TUG2 . The PDIV output is set high
when the PSL in the V5 byte is set to the bit pattern specified by the
PDICODE[2:0] register bits for five consecutive multiframes. The PDIV
output is set low when the PSL is set to any other bit pattern for five
consecutive multiframes. When PDIVEN is set high, the PDIV output is
permanently set high independent of the tributary's defect status until the
PDIVEN is set low.
TUPTE:
The TUPTE bit determines the alarm conditions under which AIS is inserted
for tributary TU #1 in the corresponding TUG2. TUPTE is set high if tributary
TU #1 is to be terminated in the network element containing this TUPP-PLUS
device. In this case, tributary AIS is automatically inserted based on the
contents of the global Tributary Alarm AIS Control register (address 10H).
TUPTE is set low if tributary TU #1 is part of the through traffic in the network
