Functional Block Diagram of the DJA Block
The functional view of the DJA block, along with interconnections to the other blocks within the Super Mapper
device, are shown in Figure 2.
The DJA block interfaces only to the cross connect and microprocessor interface blocks within the Super Mapper
device. The input interface between the DJA block and the cross connect block consists of clock, serial data, VT
pointer adjustment indication, and AIS insert indication. The output interface consists of clock, serial data, and AIS
insert indication, as well as the DS1 and E1 AIS clocks for use by other blocks within the device.
