5.1.4 X.31
Packet-switched data transmission (X.31)
To improve customer service, you wish to allow cashless payment methods such as debit
or credit card, or record purchase data for a customer card. For this purpose, you connect
a data device to your system, which transmits data for customers and credit cards to a
central location.
You can connect a data device which operates according to the X.31 transmission stand-
ard (data transmission over the D channel) to the system's internal ISDN connections.
These are, for example, checkout terminals, cashpoints or customer card terminals.
For use of these performance features, your network operator provides you TEI's
(Terminal Endpoint Identifier), which you assign to individual connections when configur-
ing your system. An additional addressing of these terminals occurs via these TEI's.
Note
You can only use this performance feature if performance feature X.31 has
been requested from the network operator, and you operate a correspond-
ing terminal on this connection. For information on operation, please see the
user's guide for your terminals.
