Telstra phone service falls victim to software glitch

A fault within Telstra's switching equipment at a Northwestern Sydney exchange cut phone access for thousands of users yesterday (Monday January 28 2002).

A Telstra spokesperson said faulty software within a node, which houses the Ericsson remote subscriber switch (RSS) switching equipment, brought down the system early Monday morning, affecting 79,000 phone lines.

The spokesperson was unable to confirm whether new software had been recently installed or if the system had just failed.

He said the node was unable to self start, and Telstra technicians were unable to remotely boot the system.

"Telstra technicians and Ericsson technicians were dispatched and the software was corrected on site. They were able to reboot the node using a computer."

The failure occurred at the Ryde exchange about 5.30am (AEDT), cutting service to Ryde, Ashfield, North Ryde, Epping, Five Dock and Drummoyne. The problem was fixed at 8.15 am (AEDT).

The spokesperson said Telstra would be investigating why the node failed.
