Remote Access Verification
To verify that each system can access the other, on each system:
1 Click Virtual Connections > Virtual Tie Lines .
2 Click the Query Remote tab.
3 In the Query Remote window, type the IP address of the remote system in
the IP address field and click Query .
If the verification is successful, the window displays the VTLs configured
at the remote site.
Example: You have installed an system in Chicago, Atlanta, and Dallas,
and you have configured two VTL connections on each of the Chicago
and Atlanta systems. The IP addresses of the three systems are:
■
Chicago — 192.168.15.100
■
Atlanta — 192.168.25.100
■
Dallas — 192.168.35.100
The Atlanta system (IP address 192.168.25.100) shows two installed but
idle VTL connections. If you execute the Query Remote operation from
the Atlanta office and specify the IP address of the Chicago system, the
local system displays two installed but idle VTL connections.
If the local system fails to access the remote system, it displays an error
message.
If you have not yet configured the remote system to support VTLs, this
message indicates that you must do so before the Query Remote
operation can succeed.
If you have configured the remote system to support VTLs, the error
message indicates that the local system cannot access the remote system
using the IP address you specified. To correct the problem:
1 Verify that you specified the correct IP address for the remote system.
2 Verify that the remote system is running properly.
3 Verify that the remote system is using the dial plan which you modified to
configure VTLs on that system.
4 Work with your network administrator to verify that WAN connection
between the two sites is properly configured and is working.
5 Verify that the VTL extensions are included in the Devices Using
Pretranslator table.
