Avaya IP Office

The Avaya IP Office platform is the ultimate in converged voice and data technology. IP Office brings a combination of voice and data applications formerly reserved for only the largest corporations. Cutting edge customer service with easy to use tools is now available to the smallest of businesses.





Connecting a Transactional Pad

A transaction pad (T-PAD, credit card "swipe" terminal) can use the ISDN (B channel) trunks, via the 25-pin D-type connector on the rear of the system control unit. This allows for faster transactions then provided by conventional modem connectivity.

The control unit supports a single DTE port. This DTE port has an AT command interface. Certain AT commands may be sent to the serial port so that it runs an X.25 T-PAD interface.

The ISDN link between the Control Unit and the transaction pad is digital. The transaction pad does not require a modem.

Configuration Parameters

In order to connect to a remote server, the DTE port needs:

  • the Phone number of the remote server

  • local_nua

  • nui

  • lower_channel (defaults to 1024)

  • upper_channel (defaults to 1279)

AT commands need to be issued to the DTE port to enable the interface. The following AT commands are relevant to transaction pad operation:

  • ATB6 - set connection mode as TPAD

  • AT%A - set the local nua.

  • AT%I - set the nui.

  • AT%L - set the lower channel limit (defaults to 1024).

  • AT%U - set the upper channel limit (defaults to 1279).

  • AT&A - set an autodial number.

  • AT&D=1 - dial autodial number whenever DTR is raised (by pad).


AT&A 01923111111

Configuration Auto-Load

Though AT commands can be issue to the DTE port through a serial communications program such as Hyperterminal, DTE port settings and parameters are not saved in the IP Office Control Unit's flash memory. Thus they are lost during any reboot.

In order to 'permanently' set the parameters they need to be added to the configuration through the IP Office Manager application. This is done through a configured user called DTEDefault.

Create a user called DTEDefault and add the required initial AT commands into the SourceNumbers table. These commands are then automatically reloaded following any reboot.


There are a number of locations where the transaction can be traced using the IP Office Monitor application.

  • Options/DTE

    • DTE Command Tx/Rx
      This trace information is output when the DTE port is in AT mode

    • DTE Filter Tx/Rx
      This is trace information of the Serial communication between the DTE port and the pad. Other trace information will appear from time to time.
