Configuring POS terminal access
This chapter describes how POS terminal access operates and how to configure POS terminal access.
Overview
The point of sale (POS) access service is a smart card service. It enables a POS terminal to access a bank
card accounting system.
Basic concepts
POS terminal
A POS terminal refers to a POS terminal device in this chapter.
POS access device
A POS access device is a router responsible for the datagram forwarding between POS terminals and a
bank front-end processor (FEP).
POS application
A POS application is a logical concept on the FEP. It identifies an application on the FEP.
POS terminal template
A POS terminal template is a logical concept on the POS access device. It stores the configuration for a
POS terminal on the POS access device. The template for a POS terminal using TCP access mode stores
the port number for listening to the terminal packets on the router. The template for a POS terminal using
dial-up or flow access mode stores the router interface connected to the POS terminal.
POS application template
A POS application template stores the configuration for a POS application on the POS access device.
•
The template for a POS application using TCP communication mode stores the IP and TCP port
number of the FEP.
• The template for a POS application using flow communication mode stores the router interface
connected to the FEP, such as Async6/0.
Application mapping table
The application mapping table stores the maps between the TPDU originator and destination addresses
and the application template ID. With this table, the POS access device finds the correct application
template according to the TPDU originator and destination addresses in a packet received from a POS
terminal, and then sends the packet to the FEP.
Instance
Instance includes POS terminal instance for the POS terminal connection and POS application instance
for the POS application connection. It stores the connection information dynamically. Instances inherit the
parameters configuration of a template.
