Peerless Industries KX-TDA200 manual Virtual Private Network VPN, Public/Private Discrimination

1.28 Networking Features

1.28.2 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 ( 1.9.1 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.
