It's not an April Fools' joke. Tomorrow, on April 1, Frontier is expected to complete its acquisition of Verizon's customer footprint in California, Florida and Texas. While some of the networks in those regions are still copper-based, more than half are FiOS-enabled.

The move, which is costing Frontier Communications Corp. (NYSE: FTR) $10.54 billion, adds more than 1 million residential video customers to the roughly half-million the company has today, and more than 2 million residential Internet subscribers to the 2.5 million data customers Frontier reported in the fourth quarter.

Frontier didn't break out its total number of voice customers last quarter, but when it announced the acquisition more than a year ago, it reported 3.9 million voice customers, with the projection that it would gain 3.7 new voice subscribers from Verizon markets.

In short, when the takeover is complete, Frontier will roughly double in size.

The shift by Frontier is noteworthy because of the massive consolidation currently underway in the US broadband and pay-TV markets. Frontier is about to become one of the few significantly-sized service providers that isn't a cable company beginning with the letter "C".

The news is also important because of what it means for Verizon Communications Inc. (NYSE: VZ). The grand FiOS experiment that began more than a decade ago has wilted in recent years as Verizon has transferred its focus to wireless projects, and, more critically, wireless profits.

Verizon hasn't given up on wireline altogether. The company did just spend $1.8 billion to acquire XO Communications and further build up its fiber network. Plus, Verizon is reportedly close to wrapping up an RFP process that will decide the vendors for a planned fiber upgrade project using next-generation PON technologies.

However, Verizon's wireline strategy appears to center more on enterprise services and cellular backhaul than it does on residential services. The telco has said it remains committed to its FiOS footprint on the east coast, but with even the director of FiOS TV promoting Verizon's Go90 OTT mobile video service over her own product, it's hard to know how seriously to take the company's official position.

As for Frontier, the upstart video and broadband provider isn't likely to sit on its new assets and let them molder. Arris Group Inc. (Nasdaq: ARRS) CEO Bob Stanzione expressed his opinion last fall that Frontier would invest in expanding the FiOS plant, and Frontier President and CEO Daniel McCarthy has been vocal about his plan to expand TV and broadband service to new customers.

Most recently, Frontier Director of Strategic Planning David Curran also talked to Light Reading about Frontier's evaluation of open networking technologies, and the company's particular interest in CORD implementations -- the idea of a Central Office Re-architected as a Data Center. With possible migrations to new open networking technologies, Frontier hopes to be able to better scale to higher broadband speeds and higher numbers of subscribers.
