Terminal Adapter - What's New In Communications Magazine

A terminal adapter has been developed for Telstra that enables retailers to connect phones, faxes, PCs and multiple EFTPOS terminals to a single ISDN line through the Telstra Argent network.

A retail outlet's communication network normally consists of 2,3 or even more phone lines, plus one leased or dial-up line for financial transactions. The Argent strategic transaction network allows business to integrate its telecommunication operations onto a single ISDN line. However, having one line does not mean that only one business function can operate at any one time. The ISDN line can be used for up to three unhindered simultaneous operations. One staff member can be on the phone talking to a customer, while another is using the PC and internet while remaining staff are processing EFT transactions. Several simultaneous functions can be completed due to the three channels within an ISDN line.

The ISDN line consists of one D-Channel dedicated to EFT transactions and 2 B-Channels that are used for voice, fax or data communications.

The Argent network consists of 16 processing units in four geographically located positions. Therefore, if one unit goes down then the network is automatically routed to the next unit.
