A number of companies are looking to buy various business units of bankrupt Nortel networks, according to the Wall Street Journal.

Nokia Siemens Networks of Nortel, the newspaper reported Wednesday.

Also, privately held Genband in Plano, Texas, is “formulating a bid” to buy Nortel’s carrier networks group, the Journal said.

Nortel employs some 2,000 people at its campus in RTP.

Nortel spokesman Jay Barta told the Journal that "planning is under way and we are pursuing opportunities that we believe will provide maximum benefit to our key stakeholders, including our creditors, customers and employees."

The latest reports about Nortel possibly selling parts of its operations come on the heels of stories last week that Avaya and Siemens Enterprise Communications are looking to buy Nortel’s business telecom group.

According to “people familiar with the matter,” Nokia Siemens is looking to buy “large parts” of Nortel’s carrier networks group, including a research and development group focused on emerging wireless technology known as LTE.

Genband reportedly wants to buy a Nortel group focused on digital switches and media gateways that link current gear with newer technology.
