Code Message
Default
Severity
Interpretation
31 LOSS OF POINTER Major The STM loss of pointer (LOP) state is entered when N
consecutive invalid pointers are received by the specified
VC-4/ STS-1.
LOP state is exited when 3 equal valid pointers or 3
consecutive AIS indications are received
32 SIGNAL DEGRADED ERROR Minor The bit error rate of the received STM-4/OC-12, VC-4, or
STS-1 signal exceeds the preset signal-degraded threshold
33 EXCESSIVE BIT ERROR RATE Major The bit error rate of the received STM-4/OC-12, VC-4, or
STS-1 signal exceeds the preset excessive BER threshold
34 FRAME LOSS Major The loss of frame (LOF) state is entered when an out-of-
frame (OOF) state exists at the specified STM-4/OC-12 port
for up to 3 ms. If OOFs are intermittent, the timer is not
reset to zero until an in-frame state persists continuously for
0.25 ms.
The LOF state is exited when an in-frame state exists
continuously for 1 to 3 ms
35 TX FAIL (TX PWR OUT OF RANGE) Major The laser TX power monitor reports a value that exceeds the
high alarm level
36 TX DEGRADE (LASER BIAS) Major The laser bias monitor reports a value that exceeds the high
alarm level, and may degrade the laser performance
37 Reserved for future use
38 STM OUT OF FRAME Major Loss of frame alignment for the specified STM-4/OC-12 port
39 Reserved for future use
40 STM PATH TRACE UNEQUIPPED Minor The specified VC has received an unequipped path trace label.
This alarm condition may often occur while a new trail is
being prepared
41 to
48
Reserved for future use
49 FAN FAILURE Minor The internal cooling fan of RICi-622GE is not operating.
Replace the unit as soon as possible
50 LAN NOT CONNECTED Major The LAN interface of RICi-622GE is not connected to an
active Ethernet LAN (this alarm will not appear when the
corresponding LAN port is disabled by the user).
Check the connection between the LAN port and the LAN
media, or hub port, and make sure that the LAN equipment is
operating normally, and at least one station is active on the
LAN
51 TX LCAS ADD NORMAL TIMEOUT Event When using LCAS, timeout occurred when waiting to transmit
an ADD NORMAL message
52 RX LOSS OF SEQUENCE Event The sequence number of a received LCAS message is out of
sequence
53 RX LCAS CRC ERROR Event A CRC error has been detected in an LCAS message
54 Reserved for future use
55 MAC RX FIFO BUFFER OVERFLOW Event The rate of frame ingress from the WAN (from the
STM-4/OC-12 link) exceeds the egress rate to the local LAN.
