Line Functions
There are two categories of line function, ISDN Lines and Virtual Private Network (VPN) lines. The ISDN line function allows different lines to be allocated to voice and data calls, if required, and for lines to be made members of a group for incoming call routing purposes. The ISDN line is also the means by which the IPNC communicates with the INDeX. The IPNC's VPN facility additionally allows “transparent” connection to an IP address at a remote site over the wide area, via a leased line. This enables a leased circuit to be configured as a number of virtual circuits which can be used for either data or
Short Codes are configured against ISDN lines to translate the dialled digits and define which VPN line should be used (see "The ShortCode Function" on page 42).
ISDN Lines
This configuration form is used to configure the use of channels available on the IPNC. Highlight the required ISDN Line in the Configuration tree and double click in the Display Panel.

Voice Channels: Controls the number of channels available for voice.
Incoming/Outgoing Group ID: One group can contain multiple lines. Short Codes and Incoming Call Routes use these numbers to indicate which line they are to use.
Number Of Channels: Defines the number of operational channels that are available on this line. Always set to 32 for IPNC.
Data Channels: Controls the number of channels available for data use. If left blank the value will be 0.
TEI: Terminal Equipment Identifier. For VPN lines, this should always be set to zero. Not applicable to the IPNC.
