Meet the Street: The Growing Power of Cable Modems

Cox Communications tapped Riverstone Wednesday for some Internet gear that will help the cable service spread broadband delivery over its network. Riverstone, once a division of Cabletron Systems, is edging out into its own as a router maker and would-be challenger to Cisco on a few fronts.

Notably, one of the few areas in tech showing signs not just of life, but of growth, is in cable modem equipment. Suresh Gopalakrishnan, Riverstone's chief technology officer and a former engineer with tech heavyweights Sun Microsystems and Hewlett-Packard, offers his view of cable's spreading influence as a Net access pipe. In particular, we ask him to shed some light on a battle heating up in a little patch of the market known as cable modem termination systems, or CMTS, where Cisco currently reigns.

TheStreet: It seems not too long ago that the CMTS market was a sleepy corner of tech that Cisco dominated. Now we have a relatively big acquisition by Juniper recently, and you folks have been making some noise with your product. What's brewing?

Gopalakrishnan: I think everyone is realizing that cable is the most effective medium for delivering residential voice and data. And we see a lot of cable companies going into the data market these days. That seems to be keeping people's interest in cable.

TheStreet: Is it fair to say that what little spending there is, is shifting much like on the phone networks away from the core and toward the edge?

Gopalakrishnan: Two things are happening: There is definitely an increase in spending toward the edge. Then, on top of that, there're lots of plans to build out more network capacity among cable companies. The current needs have been driven by broadband residential access, and what cable companies want to get into is business services where they can make a lot more money. And when they go into that kind of business, they really have to make sure they have enough capacity on the backbone to serve that need. So there's definitely spending on both sides.

TheStreet: Cisco has 80% share of the CMTS market. Do you think you'll chip into that in 2002?

Gopalakrishnan: Yes. If you look at our products, you'll see there are a significant number of differences. Our product is a card that goes into our router and serves as a single-box solution with cable on one side and any kind of network attachment on the other side. The current Cisco offering is a two-box architecture. But I can't make any predictions on market share.
