RICi-622GE Ver. 1.0 Handling Alarms and Traps 6-17
Code Message
Default
Severity
Interpretation
6 CLOCK CHANGE TO INTERNAL Event RICi-622GE has switched to the internal clock source
7 CLOCK CHANGE TO MASTER Event RICi-622GE has returned to the master clock source
8, 9 Reserved for future use
10 SP-PAR SWITCH IS ON Minor Section 1 of the internal switch SW1 is set to the OPEN
position. This caused reloading of the default communication
parameters for the supervisory terminal port (CONTROL
connector).
If it is no longer necessary to enforce the default parameter
values, return this switch section to the CLOSE position
11, 12,
13
Reserved for future use
14 SIGNAL LOSS Major The specified port of RICi-622GE reports loss of input signal
15 to
22
Reserved for future use
23 LINE CODE VIOLATION Event A bipolar violation (BPV) error has been detected by the
specified PDH port. This alarm may also appear when an
excessive zeroes error occurs (more than three consecutive
0s for an E1 port, or more than 8 consecutive 0s for a T1
port using B8ZS zero suppression)
24 AIS OCCURRED Major The Alarm Indication Signal (AIS), a framed "all ones"
sequence, is received by the specified PDH port, VC or VT.
AIS on an E1 link is declared when less than three spaces
(i.e., two or fewer zeros) are detected in a sequence of 512
bits (256 μsec window).
AIS on a T1 link (blue alarm) is declared when less than five
spaces are detected in a 3-msec window
25 Reserved for future use
26 UPPER LAYER CRITICAL ALARM Major A critical error has occurred on an upper layer for the
specified VC-4/STS-1
27 PAYLOAD LABEL UNEQUIPPED Major The specified VC-4/STS-1 receives an unequipped payload
label (signal label).
This alarm condition may often occur while a new trail is
being prepared
28 PATH TRACE ID MISMATCH (TIM) Major The path trace ID received from the far end does not match
the expected ID for the specified VC-4/STS-1. This may
indicate incorrect routing of the corresponding VC-4/STS-1
29 PAYLOAD LABEL MISMATCH (PLM) Major A payload label mismatch has been detected for the specified
VC-4/STS-1. This may indicate incorrect routing of the
corresponding VC.
This alarm condition may often occur while a new trail is
being prepared
30 REMOTE DEFECT INDICATION (RDI) Major RDI (Remote Defect Indication) is received from the remote
equipment through the specified STM-4/OC-12 link
