Function

SAC1FP

Input

B11 SBI Add C1 Frame Pulse (SAC1FP). The Extract C1

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.

SADP

Input

A14 System Add Bus Data Parity (SADP). The system

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.
