SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
TU #4 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 #4 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:
The RDIZ7EN indicates which tributary path overhead byte is used for
controlling the ERDI[2:0] or RDI/RFI bits of tributary TU #4 in the
corresponding TUG2 . 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.
