ISDN Access & Calls

ISDN is a high-speed method of sending voice and data on a digital phone line to national and international destinations. The speed and clarity of ISDN means your customers can send and receive text, voice, video and images in seconds.

With Telstra ISDN products and services under a resale arrangement, you can market ISDN basic rate access services, including ISDN 2 and ISDN 2 Enhanced.* If your customers require more lines you can choose from primary rate access services that provide 10, 20 or 30 digital lines.

ISDN services can also be used to build network tails to access Frame Relay, ATM or DDS networks, and to establish infrastructure for internet dial access for your customers.

* Subject to any ISDN capacity constraints.
