More information The Packet Loss Threshold and Round Trip Delay Threshold fields work like this:
• If the value in either High field is exceeded, access to the IP trunk group is
blocked.
• Access to the IP trunk group is only allowed again when the average for both
measurements drops below the values in the Low field.
Placing a test telephone call
To place a test telephone call to the remote switch over IP trunk service:
1 Contact the switch administrator at the remote site to verify that IP trunk service
is set up on the remote switch:
~ The connection between the MAPD circuit pack and the switch is configured
~ Dial plan and routing is administered
~ IP trunk service is started
2 Dial the telephone number of the remote site.
For example, if prior to installing IP trunk you dialed 9, then 011 plus the country
code followed by the telephone number, then dial the number the same way to test IP
trunk service.
If your call does not go through, refer to Troubleshooting IP Trunk (page 448).
Setting up alerts on IP trunks
Whenever something happens on IP trunks that might affect service quality,
Windows NT™ can display an alert in a popup window. You can select the IP address
for the alert messages and notify a computer other than the IP trunk display screen.
NT alerts allow you to monitor IP trunk service on one or more switches.

1 Go to NT’s Control Panel.
2 Double-click Services.
3 Select Messenger and click Start.
Started appears in the Status column.
4 Select Alerter and click Start.
Started appears in the Status column.
5 Click Close.
To specify the computers on which alerts should be received:
1 Go to NT’s Control Panel.
2 Double-click Server.
3 Click Alerts.
The Alerts dialog box appears.
