ALARM CRITERIA Table 4-2
ALARM
SET CRITERIA
CLEAR CRITERIA
Blue Alarm (AIS)
(see note 1 below)
when over a 3ms window, five
or less 0s are received
when over a 3 ms window, six or
more 0s are received
Yellow Alarm (RAI)
1. D4 bit 2 mode(RCR2.2=0)
2. D4 12
th 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 12
th 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 12
th 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)
(this alarm is also referred to as
Loss Of Signal)
when 192 consecutive 0s are
received
when 14 or more 1s out of 112
possible bit positions are received
starting with the first one received
NOTES:
1. The definition of Blue Alarm (or Alarm Indication Signal) is an unframed all 1s signal. Blue alarm
detectors should be able to operate properly in the presence of a 10-3 error rate and they should not
falsely trigger on a framed all 1s signal. The blue alarm criteria in the DS2152 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 DS2152 does; the following terms are
equivalent:
RBL = AIS
LRCL = LOS
RLOS = LOF
RYEL = RAI
