frame pulse synchronizes devices interfacing to the
Extract SBI bus. The frame pulse indicates SBI bus
multiframe alignment which occurs every 500 µS,
therefore this signal is pulsed every 9720 SREFCLK
cycles (38880 cycles if S77 is high). This signal does
not need to occur every SBI multiframe.SAC1FP is
sampled on the rising edge of SREFCLK.
System Add Bus Data (SADATA[7:0]). The System
add data bus is a time division multiplexed bus which
carries the E1, T1 and DS3 tributary data is byte serial
format over the SBI bus structure. This device only
monitors the add data bus during the timeslots
assigned to this device.
SADATA[7:0] is sampled on the rising edge of
SREFCLK.
add bus signal carries the even or odd parity for the
add bus signals SADATA[7:0], SAPL and SAV5. The
TEMAP-84 monitors the add bus parity during all
cycles when S77 is low and during the entire selected
STM-1 when S77 is high.
SADP is sampled on the rising edge of SREFCLK.
