4-2 Solo E1 DSU User Guide—June 1998

If SNMP is enabled, SNMP TRAPs are sent as conÞgured in Menu-0 SNMP

ConÞguration (see Figure 3-6 on page 3-16); otherwise, the connection

indicated in Menu-8 Alarm II (see Figure 3-10 on page 3-22) identiÞes the

alarmsÕ are sources.

If SNMP is not enabled, the alarm shows up at the bottom of the screen

and scrolls. The alarm automatically goes away when the screen is

refreshed.

When the terminal is connected to the COMM port and you are logged on,

alarms are shown at the bottom of the screen (but above the menu choices).

For example, a carrier loss condition on the DATA port shows as (if the

device is set to use SNMP, all information passes to the NMS):

--Local ID:Oahu Data1 Carrier Loss Start: 07:17:37

1/12/97

The alarm information is:

¥ Local or remote device

¥ Unit ID

¥ Type of alarm

¥ Start or end of alarm condition

¥ Date and time.

The alarm remains on the screen until a new alarm occurs or until you

select a new menu. When no alarm is present, a dotted line is shown.

In SNMP mode, the device sends the alarm as an SNMP TRAP to the NMS

and it does not send Þle text to the screen.

If the local Solo E1 is connected to a modem and an alarm occurs, the Solo

E1 causes the modem to dial out if in Menu-8 Alarm II (see Figure 3-10 on

page 3-22) Connection is set to Modem; valid telephone numbers are set in

Phone Number 1 or Phone Number 2).

Menu-1 Main Status

The Solo E1 DSU counts error conditions on the network and DATA ports
