Figure 60 shows three DS-3 tributaries mapped onto the SBI bus. A negative
justification is shown for DS-3 #2 during the H3 octet with SDPL asserted high. A
positive justification is shown for DS-3#1 during the first DS-3#1 octet after H3
which has SDPL asserted low. E3 is transported by the same mechanism.
13.7 SBI ADD Bus Interface Timing
The SBI ADD bus functional timing for the transfer of tributaries whether T1/E1 or
DS3 is the same as for the SBI DROP bus. The only difference is that the SBI
ADD bus has one additional signal: the SAJUST_REQ output. The
SAJUST_REQ signal is used to by the TEMAP-84 in SBI master timing mode to
provide transmit timing to SBI link layer devices.
