Sa8 Source Control.
A 1 indicates that Sa8 is sourced from this
block. 0 indicates that Sa8 is sourced from the framer Sa stack.
Sa7 Source Control.
A 1 indicates that Sa7 is sourced from this
block. 0 indicates that Sa7 is sourced from the framer Sa stack.
Sa6 Source Control.
A 1 indicates that Sa6 is sourced from this
block. 0 indicates that Sa6 is sourced from the framer Sa stack.
Sa5 Source Control.
A 1 indicates that Sa5 is sourced from this
block. 0 indicates that Sa5 is sourced from the framer Sa stack.
Sa4 Source Control.
A 1 indicates that Sa4 is sourced from this
block. 0 indicates that Sa4 is sourced from the framer Sa stack.
FRM_TXCRCSM
CEPT CRC-4 Stack Mode.
When set to 0, the Sa bits will be
transmitted based on being active. If MFA is lost, the stack will
not be transmitted. When set to 1, the Sa bits will be transmitted
based on BFA only.
FRM_ASRC
Alignment Source.
A 1 indicates that the MFA and BFA will be
used to determine if a BOM or stack is transmitted. A 0 indicates
that, when enabled for insertion, BOMs and stacks will be
inserted whenever the TDM data is requested.
FRM_DS1I
DS1 Insertion.
A 1 enables this block to insert the contents of
the stack into the associated DS1 link. For SLC-96 links, D bits
will be inserted given the associated stack format. For DDS
links, data-link bits will be inserted given the associated stack
format. For other DS1 link types, this bit has no effect. A 0 dis-
ables this block from inserting D bits or data link bits into the
associated link.

Transmit Bit Oriented Message Enable.
A 1 indicates that the
BOM message register has been initialized and should be transmit-
ted on the data link of the ESF frame. The pattern will continue to
be transmitted until the enable is removed. When set to 0, the BOM
transmission will stop immediately without completing the current
pattern transmission or without completing the series of 10 pat-
terns.
FRM_TBOM[5:0]
Transmit Bit Oriented Message.
Indicates the contents of the
BOM to be transmitted when enabled with FRM_BOME. A pattern
of 111110 implies a BOM of 0111110011111111 with the right
most bit being transmitted first.
