After you have configured the VTLs on each of two NBX systems, you 
must verify that the VTL connection works properly.

To verify that a working VTL connection exists between two systems, you 
must verify that:

■

 — Verify that the configured VTLs appear on 

each system.

■

 — Verify that each of the systems can 

access each other.

■

 — Verify that telephone calls can be made 

between all pairs of connected systems in both directions.

On each system you must verify that you can view the VTLs using the NBX 
NetSet utility. To verify that you can view the local VTLs:

1 In the NBX NetSet - Main Menu window, click Device Configuration.

2 Click the Virtual Tie Lines tab.

3 Verify that all of VTLs you have configured appear in the list.

In our example, if you perform this verification test on the Chicago NBX 
system, the results appear as shown in 

.
