Setting up ISDN D channel X.25 support

This section discusses support of nailed X.25 connection over the D channel, but T3POS,
X25/PAD, X25/IP, X25/PPP, and X25/MP (AO/DI) protocols are also supported over any
channel that supports nailed X.25 connections (for example, B channel and serial WAN).

Customized X.25 T3POS support
MAX units with X.25 support X25 Transaction Processing Protocol for Point-of-Service
(T3POS), which can be used to send point-of-sale (POS) data over the ISDN D channel.
T3POS is a character-oriented, frame-formatted protocol designed for POS transactions
through an X.25-based packet switched network. T3POS enables you to send data over the
ISDN D channel while continuing to send traffic over both B channels. The T3POS protocol
involves three parties: the T3POS DTE (DTE), the T3POS PAD (PAD) and the T3POS Host
(host), as shown in Figure 6-3.

Open Ethernet > X25 > any X25 profile.
Set TEI to the value specified by your X.25 carrier.
You can set TEI to any value from 1 to 63 for fixed TEI. The default is 21. If you set TEI
to 0 (zero), the MAX will use a TEI assigned by the network.
Set Call Type to D channel.
Exit the profile and, at the exit prompt, select the exit and accept option.
