X.25 Tab

This tab is visible only if the data protocol is set to ‘MultiLink PPP with AODI’.

As AO/DI uses the ISDN D-channel X-25 packet service to maintain an “always on” connection
between you and your Service Provider, there are X.25 parameters that can be configured.
These are X.25 Facilities and your X.25 Version. This information is provided by your Service
Provider.

Description

Packet
Telephone
Number

A Packet Telephone Number identifies a node on an X.25 network. The address is a
series of one to fifteen digits. Every X.25 node has a Packet Telephone Number.

It defines the D-channel's DTE address for communication with the local packet
handler. This parameter allows the DIVA T/A to activate the D-channel during
initialization and give its address to the switch.

This value is assigned by your ISDN provider at subscription time.

X.25 Version

ITU (formerly CCITT) reviews and makes international standards recommendations
for communications protocols. X.25 is a CCITT recommendation for the interface
between Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment
(DCE) for packet-switched data networks (PSDNs).

There are two X.25 CCITT recommendations available for selection, 1984 and 1988.
This information is provided by your Service Provider and should match the X.25
recommendation supported on the switch you are connecting to.
