Reserved for future use
60 RX LAPS/FRAME MISMATCH Minor This alarm indicates a mismatch in the ADDRESS, CONTROL,
or SAPI fields of the received LAPS/LAPF frame. This alarm is
set (ON) after the detection of any one of these errors and
is reset (OFF) after the user displays the statistics counters.
61, 62 Reserved for future use
63 NUMBER OF VCS UNDER MINIMUM Major When using LCAS, the number of active VCs per group can be
changed dynamically. This alarm is set (ON) when the number
of active VCs drops below the minimum configured value
(defined in the Logical Layer Configuration menu), and is
reset (OFF) after the failed VCs recover, or the configuration
is changed
64 GFP OUT OF SYNC Major When GFP is used, the GFP multiplexer subsystem serving the
LAN interface has lost synchronization to the incoming
stream
65 DIFFERENTIAL DELAY EXCEEDS MAX Major This alarm is set (ON) when the differential delay exceeds the
maximum delay configured in the database for the
corresponding virtual group, and is reset (OFF) when the
delay decreases below the maximum value.
66 TX LCAS ADD ACK TIMEOUT Event When using LCAS, timeout occurred when waiting to transmit
an ADD ACK message
67 TX LCAS REMOVE ACK TIMEOUT Event When using LCAS, timeout occurred when waiting to transmit
a REMOVE ACK message
68 GFP CHANNEL ID MISMATCH Event The GFP multiplexer subsystem has detected an unexpected
channel number (CID)
69 CLOCK FAIL Major The internal clock oscillator serving the STM-4/OC-12 ports
failed
70 LOSS OF MULTIFRAME Major Loss of multiframe synchronization occurred on the specified
VC-4/STS-1
71 Reserved for future use
72 SOFTWARE DOWNLOAD FAIL Event Software downloading to RICi-622GE failed. Repeat the
process
73 NETWORK LINE LOOPBACK Major The alarm is set (ON) when a network-initiated line loopback
has been activated on the corresponding port. This loopback
cannot be disconnected by the system management.
The alarm is reset (OFF) after the loopback is deactivated
74 SOFTWARE DOWNLOAD Event Software is being downloaded to RICi-622GE
75 FLIP OCCURRED Event Flipping to the alternate path occurred
76 REMOTE FAIL INDICATION Major A remote fail indication has been received by the specified
VCG.
77 CLK IS DIFF FROM MASTER CLK Major RICi-622GE is not using the clock source selected as master
source. This indicates a major failure in the source that
provided the master clock source
78 UPPER LAYER CRITICAL ALARM Minor A critical error has occurred on an upper layer for the
specified VCG.
