Using a VTL Password111
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.
Figure 43
 shows how to configure VTL passwords in a dial plan, using site 
codes that permit hop-off and other site codes that do not. Each entry is 
explained following the figure.

The first TableEntry Create command creates entry 100 in Table 1. This 
assumes that the highest previous entry in Table 1 was 99 or lower. Entry 
100 watches for the 2-digit sequence 62 followed by a 4-digit extension 
and specifies route 522 whenever a user dials such a 6-digit (Min = 6 and 
Max = 6) sequence. Entry 101 watches for the 2-digit sequence 63 
followed by a 4-digit extension and specifies route 523 whenever a user 
dials such a 6-digit sequence. The choice of route...

Using a VTL Password113
For the second two DestinationRoutes, two DestinationRouteOperation 
Create commands perform two similar functions.
■The stripLead command removes the two digits (72 or 73) leaving the 
4-digit extension the user dialed.
■The prepend command adds the IP Address of the destination NBX 
system and the password of that system to the extension that the user 
dialed. In this example, the IP address for Atlanta is 192.169.25.100 
and the password is ATLPassW. For Dallas, the IP address...
