The incoming data bus (ID[7:0]) carries the
STM-4 or STM-1 #1 SONET/SDH frame data in
byte serial format.
In incoming STM-1 (STS-3) interface mode
(IHSMODEB set high), the ID[7:0] bus carries
the STM-1 #1 stream. ID[7] is the most
significant bit, corresponding to bit 1 of each
serial word, the bit transmitted first. ID[0] is the
least significant bit, corresponding to bit 8 of
each serial word, the last bit transmitted. The
ID[7:0] bus is sampled on the rising edge of
SCLK.
In incoming STM-4 (STS-12) interface mode
(IHSMODEB set low), the ID[7:0] bus carries the
STM-4 stream. ID[7] is the most significant bit,
corresponding to bit 1 of each serial word, the bit
transmitted first. ID[0] is the least significant bit,
corresponding to bit 8 of each serial word, the
last bit transmitted. The ID[7:0] bus is sampled
on the rising edge of HSCLK.

The incoming data bus (ID[15:8]) carries the
STM-1 #2 SONET/SDH frame data in byte serial
format.

In incoming STM-1 (STS-3) interface mode
(IHSMODEB set high), ID[15] is the most
significant bit, corresponding to bit 1 of each
serial word, the bit transmitted first. ID[8] is the
least significant bit, corresponding to bit 8 of
each serial word, the last bit transmitted. The
ID[15:8] bus is sampled on the rising edge of
SCLK.
In incoming STM-4 (STS-12) interface mode
(IHSMODEB set low), the ID[15:8] bus is unused
and all bus signals must be strapped low.
