SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
V5 byte is set high for five or ten consecutive multiframes as determined by
the RDI10 bit in the RTOP and RTTB Configuration registers (addresses 0CH,
0DH, and 0EH). RFIV is set low when the RFI bit is set low for five or ten
consecutive multiframes as determined by the RDI10 bit. RFIV is not used
when TU3 mode is enabled.
ERDIV[2:0]:
The ERDIV[2:0] bits indicates the extended remote defect indication status of
tributary TU #1 in TUG2 #1 or the TU3 mapped in a TUG3 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 or the G1 byte is seen for five or ten
consecutive multiframes (frames in TU3 mode) 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
TUG2 #1 or TU3. 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
TUG2 #1 or TU3. The PSL unstable counter is incremented if the PSL of the
current multiframe differs from 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 controls the insertion of tributary path defect indication for
tributary TU #1 in TUG2 #1 or TU3 in the receive alarm port (RAD). When
PDIVEN is set high, PDI-V is asserted regardless of the state of the path
signal label. When PDIVEN is set low, PDI-V is asserted if the incoming path
signal label matches the PDI code in the PDI[2:0] bit of the corresponding
RTOP Configuration register.
