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 deny hop off.
To enable a system to manage incoming hop off calls, create or modify a
VTL password, as described in the next topic,
Configuring a VTL
Password .
To enable a system to send hop off VTL calls, configure the dial plan to
include the VTL password, as described in
Configuring VTL Passwords in
the Dial Plan on page 346 .
Configuring a VTL
Password
For each system that can receive VTL calls, use the NBX NetSet utility to
configure a local system VTL password.
To configure the password:
1 Click System Maintenance > Password Administration .
2 Select Virtual Tie Lines Password in the Password list, and then click Go .
3 Type the administrator password in the Current Admin Password field.
4 Type the new VTL password in the New Virtual Tie Lines Password field.
Passwords are from 8 to 15 characters in length and must contain only
letters and numbers. Upper and lower case letters are permitted.
5 Retype the new VTL password in the Re-enter New Password field.
6 Click OK .
Configuring VTL
Passwords in the
Dial Plan
For each remote system that controls hop-off by means of a VTL
password, configure that password into the VTL commands in the local
dial plan.
If you use site codes to access other systems through VTL connections,
you can configure one set of VTL connections that permit hop-off and are
accessed by one set of site codes. You can configure another set of VTL
connections that do not permit hop-off and are accessed using a different
set of site codes.
If you use unique extension ranges at each site, and therefore do not dial
a site code when placing VTL calls to users at those sites, you can still use
codes to access VTL connections that permit hop-off at the far end.
