ACCULINK 316x DSU/CSU

Alarms
The 316x DSU/CSU monitors alarm conditions
occurring on either the network interface or the DSX-1
Drop/Insert port (DTE). For Model 3160/3164
DSU/CSUs, you can route these alarms to the MODEM
port, the COM port, or both. Each alarm is preceded by
the customer identification so you know which DSU/CSU
is having the problem. Possible alarm messages are as
follows, where x is the DTE or Network interface where
the condition exists.
For Model 3161 DSU/CSUs, these alarms activate the
alarm relay, if so configured.
•
Continuous Loss Of Signal at the x Interface.
•
Alarm Cleared. Loss of Signal condition at the x
Interface.
•
Continuous Out Of Frame condition detected at
the x Interface.
•
Alarm Clear. Out of Frame condition at the x
Interface.
•
Alarm Indication Signal received at the x
Interface.
•
Alarm Clear. Alarm Indication Signal at the x
Interface.
•
An Excessive Error Rate has been detected at
the Network Interface.
•
Alarm Cleared. An Excessive Error Rate at the
Network Interface.
•
Yellow alarm signal received at the x Interface.
•
Alarm Cleared. Yellow alarm signal at the x
Interface.
If two alarm conditions are detected at once, the higher
priority alarm is reported. However, if an even higher
priority alarm is detected before the first alarm is cleared,
the later alarm is not reported.
Alarms remain active until the alarm condition is
cleared. Also, an alarm clear message is reported, unless
another alarm occurs right away. In this case, the alarm
report takes precedence over the alarm clear message.
You can specify the number of minutes to wait between
successive dial out alarms and between retry attempts
after failed alarm dial outs. For more details, refer to the
Alarm Configuration Options section of Appendix C,
Configuration Options.
SNMP Traps
If you are using SNMP to manage your 3160/3164
DSU/CSU, link-up and link-down traps are generated
when the state of an interface changes. A link-down trap
is generated when an interface transitions from an up state
to a down state. A link-up is generated when an interface
transitions from a down state to an up state. Table 4-1
defines traps for each interface.
Table 4-1
SNMP Trap per Interface
Interface SNMP Trap Meaning
Network T1 Interface is up when no alarm conditions exist.
Interface is down when an alarm condition is active.
DSX-1 (DTE) Drop/Insert Interface is up when no alarm conditions exist and the inter-
face is enabled.
Interface is down when an alarm condition is active and the
interface is disabled.
Data Ports Interface is up when the port is assigned to a T1 interface
and both CTS and DSR are ON.
Interface is down when the port is unassigned or either
CTS or DSR are off.
