Figure 51 illustrates the operation of the SBI DROP Bus, using a negative  
justification on the second to last V3 octet as an example. The justification is  
indicated by asserting SDPL high during the V3 octet. The timing diagram also  
shows the location of one of the tributaries by asserting SDV5 high during the V5  
octet. The SBIACT signal is shown for the case in which TEMAP is driving  
SPE#1 onto the SBI DROP bus.

Figure 52 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. The SBIACT signal is shown for the case in  
which TEMAP is driving SPE#2 (DS-3#2) onto the SBI DROP bus.
