PING: IT-oriented people. (DSL question)

Ben E Lou · 09-17-2004, 08:46 AM

OK, so Ivan's remnants did a pretty good number on metro Atlanta yesterday afternoon and evening. My entire neighborhood is without power, for example. However, things are strange at my small office. We have two phone lines (one voice, one fax), with DSL on the voice line. Both phone lines are dead as a doornail: no static, no sound, nothing. However, the DSL line is working perfectly. (I'm posting from it right now.) How the heck does that happen? (I've called the phone company. They checked the line and found trouble on it, so it isn't a bad or unplugged coupler or some other O.T. like that, I'm fairly certain.)

If, as I've been given to understand it, the DSL data & the voice data travel in separate "channels", then I suspect that it would be possible for some problem to exist only with the voice data "channel" -- maybe something passing through a central switching location for example.

Just a guess.

Digital Subscriber Line

DSL runs over an existing twisted pair telephone line. It is quite possible you have problems with your voice and not your DSL and vice virsa. It's hard to explain without getting too technical, but yes its possible.

Digital Subscriber Line (DSL) technology is a modem technology that uses existing twisted-pair telephone lines to transport high-bandwidth data, such as multimedia and video, to service subscribers. The term xDSL covers a number of similar yet competing forms of DSL technologies, including ADSL, SDSL, HDSL, HDSL-2, G.SHDL, IDSL, and VDSL. xDSL is drawing significant attention from implementers and service providers because it promises to deliver high-bandwidth data rates to dispersed locations with relatively small changes to the existing telco infrastructure.

xDSL services are dedicated, point-to-point, public network access over twisted-pair copper wire on the local loop (last mile) between a network service provider's (NSP) central office and the customer site, or on local loops created either intrabuilding or intracampus. Currently, most DSL deployments are ADSL, mainly delivered to residential customers. This chapter focus mainly on defining ADSL.

I'd guess it means the line is fine, but the phone switch at your central office is down.
