1.30.3 Virtual Private Network (VPN)
Description
Virtual Private Network (VPN) is a service provided by the telephone company. It uses an existing line as if it
were a private line. There is no need to set up a private line or to lease a line from the telephone company.
Making and receiving both public and private calls is possible using the same line.
Public/Private Discrimination:
a.
When making a call: The public/private discrimination number is required before sending the dialled
number to the telephone company. The public/private discrimination number can be dialled manually, or
automatically by ARS programming (® 1.10.1 Automatic Route Selection (ARS)) and/or TIE line service
programming.
b.
When receiving a call: The telephone company distinguishes the call type. If it is a private call, the call is
received by the TIE line service method. If it is a public call, the call is received by the Incoming Trunk Call
Distribution method (DIL/DDI/MSN) which is assigned on the trunk.
