0x5A—SEF/FRED/COFA Alarm Counter (AERR)
Reading AERR clears the SEF[1:0], COFA[1:0], and FRED[3:0] count values.

Receive Loss of Basic Frame Alignment Count—Increments for each occurrence of FRED
[ALM3; addr: 049]. The 4-bit count is large enough to count more than 100 ms worth of
MFAS time-out intervals (8 ms each) during E1 modes. The processor may therefore use the
FRED counter overflow interrupt to indicate that a receive MFAS alignment search has timed
out.
Change of Frame Alignment Count—Increments each time the offline framer generates a
reframe pulse that aligns the receiver time base to a new bit position.
Severely Errored Frame Count—Increments for each occurrence of SEF [ALM3; addr: 049].
