With the completion of the asset sale of Adelphia Communications Corp. on July 31, thousands of cable customers across Western Pennsylvania will soon be getting services from Comcast Corp.

That ownership transfer will result in changes in cable television, Internet and telephone services for people in more than 300 communities from Kane, McKean County, to Morgantown, W.Va.

In southern Allegheny County, communities that will see their cable systems switched include Bethel Park, Dravosburg, Homestead, Mt. Lebanon, Mount Oliver, Munhall, Pleasant Hills, West Mifflin, West Homestead, Whitaker and Upper St. Clair.

In Washington County communities such as Peters, Finleyville, Union and Nottingham will make the switch.

Eventually, everyone who has an adelphia.net e-mail address will see it switched to comcast.net.

And, sometime soon, Comcast will be pushing new services, including a new digital telephone service.

"We will start rolling out the phone service early next year, neighborhood by neighborhood," said Doug Sansom, senior vice president of Comcast Three Rivers Region.

The changes won't be immediate.

"While the deal has closed, customers will not see a whole lot of differences until late November or early December," Mr. Sansom said.

Customers will start seeing the Comcast name on the service trucks and on the letterhead of mailings.

"We need about four months to connect their different Adelphia systems to our network using some very advanced technology," he said.

By November, he said, customers can expect to start receiving their cable bills from Comcast instead of Adelphia.

He said customers will see "a lot of local video on demand, more movies, more hours of programming."

Customers who have a digital platform will be able to get new programs, such as "Steelers 24-7," which will be exclusive footage of the Pittsburgh Steelers.

Once Comcast gets the system up and running, Mr. Sansom said, service calls will be answered in Pittsburgh, not in some other region.

In most cases, he said. Comcast plans to keep the local offices that Adelphia operated in communities such as Bethel Park. He said some offices would be improved.

"We would like to move customer lobby centers to strip malls, but that won't happen until next year," Mr. Sansom said.

Adelphia Communications filed for bankruptcy in 2002 after its founder, John Rigas, and two of his sons, were arrested and charged with looting the company's assets for their personal use.

On July 31, Adelphia completed the sale of all its assets to Time Warner Cable and Comcast Corp. for $12.5 billion in cash and about 16 percent of the equity of Time Warner's cable subsidiary.

As a result, Adelphia, which has been in Chapter 11 bankruptcy, will no longer operate as a cable company. Its 4.8 million customers will be distributed between Time Warner Cable and Comcast.

In Western Pennsylvania, Mr. Sansom said, Comcast will pick up the cable service in communities from Kane to Morgantown.
