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 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.

•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.

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.
