Transmit bus input for
STS-1/STS-3c/STM-1/G.832 overhead. Tie to a
logic low level if not used.
Receive bus output for
STS-1/STS-3c/STM-1/G.832 overhead.
Used for overhead bus output. RMRKR[1] is an
8 kHz output synchronized to the received PLCP
frame. RMRKR[1] is not available in DS-3 direct
cell mapping mode.
Used for overhead bus output.
Used for bus input.
Used for bus input in modes 4, 5, 6 and 7 (OC3,
OC1, E4 and G.832 E3).
