Input
The incoming data bus (ID[23:16]) carries the
STM-1 #3 SONET/SDH frame data in byte serial
format.

In incoming STM-1 (STS-3) interface mode
(IHSMODEB set high), ID[23] is the most
significant bit, corresponding to bit 1 of each
serial word, the bit transmitted first. ID[16] is the
least significant bit, corresponding to bit 8 of
each serial word, the last bit transmitted. The
ID[23:16] bus is sampled on the rising edge of
SCLK.
In incoming STM-4 (STS-12) interface mode
(IHSMODEB set low), the ID[23:16] bus is
unused and all bus signals must be strapped
low.

The incoming data bus (ID[31:24]) carries the
STM-1 #4 SONET/SDH frame data in byte serial
format.
In incoming STM-1 (STS-3) interface mode
(IHSMODEB set high), ID[31] is the most
significant bit, corresponding to bit 1 of each
serial word, the bit transmitted first. ID[24] is the
least significant bit, corresponding to bit 8 of
each serial word, the last bit transmitted. The
ID[31:24] bus is sampled on the rising edge of
SCLK.
In incoming STM-4 (STS-12) interface mode
(IHSMODEB set low), the ID[31:24] bus is
unused and all bus signals must be strapped
low.
