Field (Bits)
Description
R_CHAN_UNSTRUCT
(15)
Set to 1 only when receiving cells with a single DS0
without a pointer in the SDF-FR mode. This bit is
valid only in SDF-FR mode. To conform to the CES
standard V 2.0 when using a single DS0 in SDF-FR
mode, no pointer should be used. This bit can be
ignored for AAL0 mode.
R_CHAN_NO_SIG
(14)
Set to 1 to receive cells without signaling when the
line is in SDF-MF mode. This is the same as using
this queue in SDF-FR mode, which means that the
structure forms on frame boundaries instead of
multiframe boundaries. The R_SIG_BUFFER will
never be updated for this queue. However, the
TL_SIG output will drive the value that was
initialized into this timeslot in T_SIG_BUFFER.
R_CHAN_DISABLE
(13)
Set to 1 to drop all cells for this queue. Set to 0 for
normal operation. Cells dropped because of this bit
are recorded in the ALLOC_TBL_BLANK sticky bit.
BITI_UNDERRUN
(12)
Set to 1 to maintain bit count integrity through
underrun. Set to 0 for normal operation.
This mode is not supported for UDF-HS mode.
Size in bytes-1 of the DBCES bit mask field.
DBCES_BIT_MASK
(11:10)
DBCES_EN
(9)
Set to 1 to enable DBCES. This bit is only valid in
SDF_FR or SDF MF mode.
