SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
TUPTE:
The TUPTE bit determines the alarm conditions under which AIS is inserted
for tributary TU #1 in TUG2 #1 or TU3 mapped in TUG3. TUPTE is set high if
tributary TU #1 or the TU3 is to be terminated in the network element
containing this TUPP+622 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 or the TU3 is part
of the through traffic in the network element containing this TUPP+622 device.
In this case, tributary AIS is only inserted when a loss of pointer (LOP) or a
loss of multiframe (LOM) alarm is detected (as determined by the global
Tributary Alarm AIS Control register).
RDIZ7EN:
Out of TU3 mode, the RDIZ7EN indicates which tributary path overhead byte
is used for controlling the ERDI[2:0] or RDI/RFI bits. When RDIZ7EN is set
low, the RDI and RFI bits in the V5 byte are used to control the RDIV and
RFIV register bits. When RDIZ7EN is set high, the three bit extended RDI
code in the Z7 byte is used to control the ERDIV[2:0] register bits.
In TU3 mode, the RDIZ7EN bit is used to control whether RDI or enhanced
RDI is reported. When RDIZ7EN is set low, the RDI bit in the G1 byte is used
to control the RDIV register bit. When RDIZ7EN is set high, the three bit
extended RDI code in the G1 byte is used to control the ERDIV[2:0] register
bits.
