DS1: This register contains the 16-bit count of received
framing bit errors. Framing bit errors are not counted dur-
ing loss of frame alignment. (T1.231 section 6.1.1.2.2.)
CEPT: This register contains the 16-bit count of received
frame alignment signal errors. Optionally, bit 2 of non-FAS
frames can be counted.
Note:
A FAS with errors in two or more bit positions is
only counted once.

FRM_CETE[15:0]
Sa6 = 00x1 Event Counter.
This register contains the
16-bit count of received Sa6 = 00x1 events. The Sa6
code is detected synchronously to the CRC-4 multiframe
and is not counted during loss of CRC-4 multiframe align-
ment. This detection is not qualified by Sa5 = 1.

Sa6 = 001x Event Counter.
This register contains the
16-bit count of received Sa6 = 001x events. The Sa6 code
is detected synchronously to the CRC-4 multiframe and is
not counted during loss of CRC-4 multiframe alignment.
This detection is not qualified by Sa5 = 1.
