Range Bits [2:0]
The Tolerance (TOLR) and Range (RANG) form the criteria for loss of
frame alignment. A loss of frame is declared if there is “TOLR out of
RANG” errors in the framing pattern. The recommended RANG value
is 5.
NOTE: A “0” value for RANG is internally blocked. A RANG value must
be specified.

0
This Read/Write bit is used to specify whether or not data link infor-
mation will be transported via National Bit Sa8 (bit 7 within timeslot 0
of non-FAS frames)
0 = Sa8 does not carry data link information
1 = Sa8 carries data link information
NOTE: This bit-field is valid only if the RxSIGDL[2:0] = “000” or “001”.
(The National bits have been configured to carry data link
bits).
