If investors are hearing crosstalk on the air today, it's because the networking industry is sending mixed signals.

Networking equipment maker ADTRAN (Nasdaq: ADTN) just reported $175 million of fourth-quarter sales, right in line with analyst estimates. Moreover, earnings trumped the Street's best guess by $0.08 per share, or 17%.

That report strikes a sharp contrast against rival Juniper Networks (Nasdaq: JNPR), which presented a gloomy preliminary report last week and blamed American telecoms for its troubles. Juniper investors are taking heart at ADTRAN's good news, sending share prices up by nearly 4%. But, the larger company still couldn't match ADTRAN's own 8% jump.

So how did little ADTRAN manage such a great quarter while larger and richer competitors couldn't? Well, CEO Tom Stanton says that broadband access and Internetworking products led the way with 49% and 37% year-over-year growth, respectively. Those divisions feed directly to telecom customers with equipment for last-mile customer connections and a portfolio of unified communications solutions.

And guess what? This means that Verizon Communications (NYSE: VZ) and AT&T (NYSE: T) probably drove ADTRAN's gravy train. In other words, Juniper can cry all it wants about a weak market for American telecom equipment -- but it actually looks more like that company is losing market share to ADTRAN and others.

So I'll jump off my soapbox regarding reticent telecoms for a while. What looked like slovenly infrastructure upgrades at first glance now just looks like shifting market shares among the equipment providers.
