OMMUNICATIONS
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bisync was superseded by SDLC.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

OURNAL
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.

ETTLEMENT
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.
