AT&T Inc. (NYSE: T) is still searching for the real killer of its Houston DSLAM cabinet, which exploded back in late October, flattening an old man's fence and sending shrapnel hurtling as far away as 50 feet down the street. (See AT&T Investigates DSLAM Explosion.)

"We continue to thoroughly investigate the possible causes of the incident, but it's still too early to speculate on the outcome of our testing," writes an AT&T spokesman, in a reply to Light Reading's inquiries.

The spokesman says AT&T has assembled a strong forensic team and is working with "one of the world's top independent technical analysis firms" to gather evidence and probe the mysterious circumstances surrounding its broadband flambé. He adds that tests are time consuming and the company can't talk about the details of the investigation while it's ongoing.

In the early going, AT&T said it would check on all the things that might have caused the explosion. AT&T in November said gas leaks, electrical issues, and vandalism were possible causes.

A non-AT&T source close to the investigation says two causes are being vetted carefully these days. The first is a high-resistance short across the battery terminals inside the base of the cabinet. The second is a possible power supply problem with the Alcatel-Lucent (NYSE: ALU) DSLAM housed in the cabinet.

AT&T apparently does know enough about the explosion's cause to say that the DSLAM cabinet caper is not a network-wide concern.

"It's also important to reiterate that this was an isolated incident involving one box out of hundreds currently used in our network," AT&T spokesman Wes Warnock writes. "We remain confident in our plans to pass approximately 19 million living units by the end of 2008 as part of our initial deployment."

Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
