14.11 Outgoing 77.76 MHz TelecomBus Functional Timing
Proprietary and Confidential to PMC-Sierra, Inc., and for its Customers’ Internal Use
Document ID: PMC-2000168, Issue 3
Figure 43 Outgoing Synchronization Timing
Figure 44 shows the timing of the Outgoing TelecomBus stream. Timing is provided by
SREFCLK. SONET/SDH data is carried on the ODATA[1][7:0] signals. The bytes are arranged
in order of transmission in an STS-12/STM-4 stream. Each transport/section overhead byte is
labeled by Sx,y and type. Payload bytes are labeled by Sx,y and Bn, where ‘n’ is the active offset
of the byte. Within Sx,y, the STS-3/STM-1 number is given by ‘x’ and the column number within
the STS-3/STM-1 is given by ‘y’. The OPL[1] signal is set high to mark payload bytes and is set
low at all other bytes. Similarly, OTPL[1] is set high to mark tributary payload bytes and is set
low at all other bytes. The composite transport frame and payload frame signal, OC1FP[1]
(OJ0J1V1[1]), is set high with OPL[1] set low to mark the J0 byte of a transport frame.
OJ0J1V1[1] is optionally set high with OPL[1] also set high to mark the J1 byte and the byte
following J1 of all the streams within ODATA[1][7:0]. Tributary path frame boundaries are
marked by a logic high on the OTV5[1] signal. Tributaries in AIS alarm are indicated by the
OTAIS[1] signal.
