Friday is a red-letter day for Nortel ... and the entire PBX industry

You may remember that earlier this year, Avaya struck a deal to buy Nortel's enterprise division out of bankruptcy for $475 million. But the process has always been set up to make Avaya's offer a "stalking horse." That means that Nortel's bankruptcy trustee has always planned ultimately to hold an auction to see if anyone wants to outbid Avaya. That auction is due to take place this Friday, September 11.

In a narrow sense, the auction is obviously key for Nortel users. For its wide base of voice equipment users -- including many companies that may use other vendors, but have lots of Nortel installations too -- the question is whether Nortel products will be actively supported, or slink along to end-of-support and ultimately end-of-life status.

Siemens' enterprise group, which itself has had a rocky few years, is mentioned as a possible bidder, as are some less likely players. But you do have to remember that much of the traditional PBX industry has already been sold out (in full acquisitions or joint ventures) to various private equity groups, who are all managing debt loads and may be wary of taking on further leverage to expand by acquisition. So Avaya could walk away with the prize with little or no further effort.

But in a larger sense, the question is whether the PBX or enterprise/unified communications industry (by whatever name) is heading inevitably for duopoly, like so many other industries. If no one outbids Avaya, then Avaya -- the ultimate successor to the original AT&T PBX business -- will gain Nortel's big if somewhat degraded distribution channel. That will leave two major players: Avaya, the champion of the traditional phone switch business, and Cisco, the behemoth data networking company that successfully clawed its way into the premises voice communications market. For all intents and purposes, enterprise managers going forward would be left with a binary choice on their strategic unified communications partner.

Does that simplify matters in the historically fractured voice equipment market, or is it an anti-competitive warning shot? And should the government step in?

That's a fascinating parallel with the emerging situation of AT&T and Verizon in the network transport (and managed) services market -- one that would have been unthinkable until recently, given the dozens of players that have given the PBX market a fair shot. Right now there is a lively debate on the matter hosted by our friends at NoJitter.com. Kind of a portal to the debate can be found in one of NoJitter editor Eric Krapf's recent e-newsletters. We'll examine the matter more after the results of Friday's auction are known, and we look forward to your views as well.
