The differential
add data
(AD[N]_p/n[3:0]) serial link carries in
bit serial format the single STS-192/STM-64 or quad
STS-48/STM-16 frame data to be transmitted by the
SPECTRA-9953. Each differential pair carries a constituent
STS-12/STM-4 of the data stream. For quad STS-48/STM-16
mode, each AD[N] group carries a full STS-48/STM-16 stream.
For STS-192/STM-64 mode, AD[1] carries STS-48 #1 (STM-
16 #1) while AD[4] carries STS-48 #4 (STM-16 #4).
Data on AD[N]_p/n[3:0] is encoded in an 8B/10B format
extended from IEEE Std. 802.3. The 8B/10B character bit ‘a(chǎn)’
is transmitted first and the bit ‘j’ is transmitted last.
The sixteen differential pairs in AD[N]_p/n[4:1] are frequency
locked but not phase locked. AD[N]_p/n[4:1] are nominally
777.6 Mbit/s data streams.
