3com SuperStack 3 NBX Manual De Usuario

To enable silence suppression on VTLs:

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

2 On the System Settings tab click Audio Settings.

3 Click the System-wide Silence Suppression on VTL Calls check box, and 

then click OK.

To allow users on one NBX system to place VTL calls to another NBX 
system and then place long-distance (toll) calls from that location (a 
practice called ‘hop off’), you can configure a VTL password.

When an NBX system receives a VTL call from a user on another NBX 
system, it can allow that user to make long-distance calls if the incoming 
VTL call contains the password. Otherwise, such calls are not allowed. If 
you set up two classes of VTL calls (with and without passwords), you can 
permit or disallow hop off.

To enable an NBX system to handle incoming hop off calls, use the NBX 
NetSet utility to create or modify a VTL password. (See the next topic, 

.) To enable an NBX system to send hop off 

VTL calls, configure the dial plan to include the VTL password. (See 

 on 

.)

For each NBX system that can receive VTL calls, you use the NBX NetSet 
utility to configure a local system VTL password.

To configure the password:

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

2 Click the Security tab.

3 Click the Virtual Tie Lines Password button. The Change Virtual Tie Lines 

Password dialog box appears.

4 Type the administrator password in the Current Admin Password text box.

5 Type the new VTL password in the New Virtual Tie Line Password text 

box.

6 Retype the new VTL password in the Re-enter New Password text box.

7 Click OK.
