Table 7-2: ALARM CRITERIA
ALARM
SET CRITERIA
CLEAR CRITERIA
Blue Alarm (AIS) (see note 1
below)
when over a 3 ms window,
5 or less zeros are received
when over a 3 ms window, 6 or
more zeros are received
Yellow Alarm (RAI)
1. D4 bit 2 mode(RCR2.2=0)
2. D4 12th F–bit mode
(RCR2.2=1; this mode is also
referred to as the “Japanese
Yellow Alarm”)
3. ESF mode
when bit 2 of 256
consecutive channels is set
to 0 for at least 254
occurrences
when the 12th framing bit is
set to “1” for two
consecutive occurrences
when 16 consecutive
patterns of 00FF appear in
the FDL
when bit 2 of 256 consecutive
channels is set to 0 for less
than 254 occurrences
when the 12th framing bit is
set to 0 for two consecutive
occurrences
when 14 or less patterns of
00FF hex out of 16 possible
appear in the FDL
Red Alarm (LRCL or RCL)
(this alarm is also referred to
as Loss Of Signal)
when 192 consecutive 0’s
are received
when 14 or more 1’s out of
112 possible bit positions are
received starting with the first
1 received
NOTES:
1. The definition of Blue Alarm (or Alarm Indication Signal) is an unframed all 1’ss signal. Blue alarm
detectors should be able to operate properly in the presence of a 10E–3 error rate and they should not
falsely trigger on a framed all 1’ss signal. The blue alarm criteria in the DS2196 have been set to
achieve this performance. It is recommended that the RBL bit be qualified with the RLOS bit.
2. ANSI specifications use a different nomenclature than the DS2196 does; the following terms are
equivalent:
RBL = AIS
LRCL = LOS
RLOS = LOF
RYEL = RAI
