POS Access Service
Configuration
Avoiding the dial-up time problem and fast connecting to the transaction
processing center.
Reducing the number of occupied communication links, hence saving the
communications cost greatly.
Avoiding the problem of service queuing as it is as though each POS terminal
device enjoys a dedicated line (except the networking is comprised of the POS
terminal and the POS concentrator).
The POS access feature can be combined with other services of the router, i.e.,
dumb terminal, SNA, and VoIP, which brings a wide market and provides users
with integrated solutions.
POS access service configuration includes:
Enable POS access server
Configure POS access port
Configure POS application interface
Configure POS application
Configure POS multi-application map
Bind the source address of TCP connection
1 Enable POS Access Server
To implement the POS access service, the POS access server must first be started.
Please perform the following configuration in system view.
Table 72 Start POS server
Operation
Enable POS access server
Disable POS access server
By default, the system disables the POS access server.
2 Configure POS Access Port
Only configured as a POS access port can the interface provide POS access service.
At present, the interfaces of the 3Com Router series, which can be used for POS
access service, include the asynchronous interface, AUX port, the
synchronous/asynchronous interface, and the FCM interface.
Please perform the following configuration in asynchronous interface view or FCM
interface view.
Table 73 Configure POS access port
Operation
Configure the POS access interface
By default, the asynchronous interface and FCM interface operate in protocol
mode, that is, no POS access port is configured.
Only when the active interface operates in protocol mode can the command be
configured.
