PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE
In either floating or locked mode, the OTMF input is used to establish the
transmit tributary multiframe boundaries on the outgoing data stream
DOUT[7:0].
The OTMFH4 bit selects the location of the OTMF in the tributary multiframe.
When OTMFH4 is set high, OTMF is pulsed high to mark the H4 byte which
indicates that the next AU3/4 or STS-1 frame is the first frame of the tributary
multiframe. When OTMFH4 is set low, OTMF marks the V1 byte of the first
tributary.
The OOP bit controls the parity placed on the outgoing parity signal OPAR.
When OOP is set low, the parity of outgoing data stream DOUT[7:0], together
with OPAR is even. When OOP is set high, the parity is odd.
