Tech Perspective: Cable modems vs. DSL

By techperspective ·
Cable modems and DSL are competing for domination in the high-speed Internet access market. If you're working from home or a small satellite office where T-1 or frame relay isn't available, you know that quality of service (QOS) is just as importantas price. According to Gartner, xDSL architecture is clearly superior to cable in terms of QOS. But if cable service is your only option, you shouldn't necessarily write it off.

Do you use cable modems or DSL for business remote access? What havebeen your experiences with it? Are you happy with your service? What complaints do you have? How important is QOS to you? Do you have a service-level agreement with your provider? If so, what does it entail?

You can read the related Gartner article, which will be posted 3 A.M. Monday, at

Originally I attempted DSL from AOL. This gave me better Internet Access speed than my 56k dial up, but this was a VPN that was not on all the time and I had to get access which took for ever.

Next I attempted to get DSL from Verizon. 8 weeks to order the line? NO way!

Now I have Road Runner Cable from Time Warner. This has been anywhere from 4x to 12x my previous dial up connection. Is this stable? NO! IT is better than dial up!

We use SDSL at work through UUnet and Rhythms Communications. We have had several outages at the onset of the service, all but one fixed by UUnet in minutes. Eventually UUnet switched us to a different PVC and we have been trouble-free since. However, our first outage lasted nothing less than 2 weeks. "Someone" at Rhythms mistakenly sent our LEC a work order to close our circuit and UUnet had to initiate a 'new customer' work order for our circuit to be restored. UUnet credited us for a month of service even though it does not offer SLAs for its DSL lines.

On a general basis, I think the article fails to mention the disparate levels of service between DSL providers. Through talking with colleagues, I have reached the unscientific conclusion that one has better DSL service by going through an ISP rather than contracting solely with the LEC. It seems LECs treat their DSL customers as just one among thousands whereas ISPs are one of the LEC's largest customers and can get things moving much faster. Case in point, our roll-out was achieved in two weeks (from order to live), while the *average* roll-out for LEC-only DSL customers in our area is 4 weeks !

First I would like to reply to the old wive tales and mis-information being spewed out about Cable modems being shared, and compromising bandwith.

1. Cable and DSL and availabilty is geographically specific.

2. The cable provider in our area use's programmable modems, and there would have to be a million user logged on, simultaneously for the network to bog down.

3. We are locate in So. Cal., and use both Charter Pipline Cable Modem service and Pacbell DSL. The pricing and performance are nearly identical. However when it comes to reliablilty, the cable modem is without question superior to DSL.

I have had ADSL in my home office since Oct, 2000. I consistently get 1.1meg to 1.2 meg down and 250K to 350K up (using DSLReports.com speedcheck). I am 13,000' from the central switch. I have Earthlink/Sprint service. I have had Earthlink as my ISPfor several years and have been pleased with their service.

USWest (now Qwest) is my local phone service provider. Although they offer DSL in my local calliing area they do not offer it in my local area. I ariginally tried to get DSL through another provider at $40 per month and no set up fee and free modem with a 1 year contract. They were unable to negotiate a line from Qwest and after about 2 months gave up. Earthlink offered $50/mo, free set-up, free modem with a 6 month contract. I was up and running in three weeks (one week was Qwest bringing up the line from the central switch to the box in front of my house). I have experienced very little QOS problems. I had one partial day when most of Colorado apparently lost service. The Earthlink Spring Merger caused some logging on issues when the format/content of the username changed a couple of times and the mailserver address has switched back and forth a couple of times between Earthlink and Mindspring (Sprint). The only other problem was a pleasant one when it took two months and a call from me before they realized they weren't billng me...They gave me those two months free.

At our company, we use whatever we can get a hold of. We have remote business users in the East Coast as well as the West Coast. Preferrably, we prefer DSL because it's much more reliable than cable.

Case in point, we had a business user in theEast Coast connecting to our network using Cable modem. His connection got so congested that our RAS had to drop him because he was not showing any sign of activity. However, after logging out and logging back into his cable ISP, he was able to re-connect at a higher speed. We definitely were not happy with Cable.

The one thing I like about Cable is the pricing for static IP Addresses. It usually is packaged with the service so we don't have to pay extra. With DSL, you have to specify astatic IP package, which costs you a little more per month.

As for DSL, we found it has been much more reliable. True, the distance from the CO determines your connection speed, but we rather have a consistent slower speed than one that can be radically fast and slow. For all employees with DSL, the average connection speed is about 500 Kbps, which we found very reasonable. DSL is definitely our direction for its QOS.
