Table 3-3 Alarm Issuance and Clear Conditions
Item
Initial state
Issued when:
Cleared when:
The RFU-CPU detects LOCALM or
TRSELALM three times each for
more than 10msec.
The RFU-CPU detects no
LOCALM or TRSELALM
three times each for more
than 10msec.
LOCALM (local oscillator alarm)
occurs if the local oscillator lost
synchronization.
Synchronization is
recovered.
TRSELALM
(transmission/reception switchover
SW failure) occurs if the
transmission state continues for
more than 1sec.
Only by a reset.
1 RFU
failure
Cleared
IFU-CPU detects a RFU-IFU
communication error (monitoring
response).
IFU-CPU is cleared by a
single RFU-IFU
communication (monitoring
response).
Communication error among the
S-CPU, D-CPU and U-CPU.
No response to polling for 3sec
Cleared by a single
response.
2 IFU
failure
Cleared
L2SW setting failure
If setting failed four times (once for
transmission and 3 times for
retransmission)
No recovery
3 Communication
error
between RFU and IFU
Cleared
The S-CPU detects a S-RFU-CPU
communication error.
No response to polling four times
(once for transmission and 3 times
for retransmission)
Cleared by a single
response.
4 ETHER 1 link down
Issued
PHY link down 3 times each for
100msec.
Recovered from PHY link
down 3 times each for
100msec.
5 ETHER 2 link down
Issued
PHY link down 3 times each for
100msec.
Recovered from PHY link
down 3 times each for
100msec.
