STREAMLINE MERCHANT SERVICES
EMIS Technical Specification
5 COMMUNICATION LINKS
5.1 General
The connection of merchants to the Streamline mainframe, coupled with data retrieval,
requires the introduction of network management procedures for both Streamline and the
Merchant. Streamline will issue a user ID and password to each merchant which will allow
access to the relevant merchant files for collection.
5.2 Requirements
The following Streamline requirements must be considered:
i) The transmission sessions are always merchant initiated.
ii) Communication lines should be duplicated and use a variety of routes to cater for
network failures.
5.3 Options
The ability to establish a communications link between the merchant and Streamline will
depend on the capability of the respective systems.
The following information may be required by Streamline to assist the merchant to determine
the most efficient and cost effective communications link:
i) CPU hardware.
ii) Data transmission hardware.
iii) Preferred communications line type (PSTN, ISDN, Leased line).
iv) Operating system.
v) Available communications protocols.
vi) Implemented or planned data communications management software.
vii) Location.
The following communications links are supported for the collection of electronic EFTPOS
information:
Physical links:
i) PSTN (Packet Switched Telephone Network).
ii) ISDN ( Integrated Switched Digital Network).
iii) Point to Point Leased line.
iv) BT X.25 Leased line.
v) TNS UK X.25 Leased line.
Support Communication Applications:
i) TCP/IP (Transmission Control Protocol / Internet Protocol).
ii) PCTCP (Personal Computer Transmission Control Protocol).
iii) Connect Direct.
5.3.3 TCP/IP
TCP/IP is currently supported over PSTN, ISDN and X.25. Connections over PSTN use Point
to Point Protocol, with an Asynchronous V.34 connection. Connections over ISDN use Point
to Point Protocol, with either Synchronous or Asynchronous connections (V.110, V.120, X.75
or HDLC).
