INTRODUCTION

COMMUNICATIONS

The XP-series ATMs support communication with the transaction processor

using a variety of communications technologies. These include TCPIP, SNA/

SDLC, and BiSync.

BiSync

A major category of synchronous communications protocols used in mainframe

networks. Bisync communications require that both sending and receiving de-

vices are synchronized before transmission of data is started. In the IBM world,

bisync was superseded by SDLC.

TCPIP (Ethernet)

This method is used in applications where a central Local Area Network, or

LAN, is used to connect multiple ATMs to a central server. The ATM can be

treated as either a client or server on the network, while the server provides the

interface to a transaction processing system.

SNA/SDLC

Systems Network Architecture/Synchronous Data Link Control (SNA/SDLC) is

IBM’s version of bit-oriented protocol. SDLC is the link level protocol and SNA

provides the intelligence for the connection. SNA and SDLC use a series of

commands to control the flow of data through the network

ELECTRONIC JOURNAL

The ATM stores transaction records, status, and other activity data in a journal

record that is stored in the ATM’s PC hard drive. The number of journal entries

that can be stored is only limited by how much memory is available on the hard

drive.

This information can be retrieved at a later date. When needed, just the informa-

tion desired can be recalled and a printout of those records can be made. Journal

entries may be viewed, printed, saved, and archived to the terminal hard drive or

to an external memory device.

TERMINAL SETTLEMENT

A suite of close functions are provided to facilitate daily balancing of the ATM’s

internal record of transaction activity with the processor’s transaction records.
