Rx Channel [A—D] Cell Register. This register is
used in over-fiber mode to give the Rx sequencer
prior knowledge of the cell in which the last byte of
a transparent packet for a given frame is located.
Reserved. These bits must be written to their reset
default value (000000).
Rx Last Byte of Current Frame. Defines which of
the 810 SONET cells has the last byte of the
current frame in channel [A—D].
Tx Sequencer Disable. This register is used to
enable or disable channels. The default is all four
channels are disabled. In other words, the disables
on the channels must be cleared or the sequencer
will not operate.
1 = the channel is disabled; 0 = the channel is
enabled.
Reserved. These bits must be written to their reset
default value (0x000).
Channel A Disable.
Channel B Disable.
Channel C Disable.
Channel D Disable.
Channel [0—3] Payload Type and Control.
See Table 120 for receive type and mode
control summary.
Reserved. These bits must be written to their
reset default value (00000).
Payload Type. Defines the payload type being
received.
Payload Control. Allows for different options
when receiving data, such as pre- or post-
unscrambling, PPP header discard, etc.
