Telephone Executives See Need for More Voice, Data Capacity New York, April 14 (Bloomberg) -- Top executives in the U.S. phone industry said increasing demand for voice and data services around the world is driving the need for more communications networks. Speaking at Morgan Stanley Dean Witter's Third Annual Global Telecom Conference in New York, executives said more consumers are hooking up to the Internet daily, creating a need for more phone and data lines. ''There's surging demand and a shortage of capacity,'' said Howard Janzen, chief executive of Williams Communications, a unit of the Williams Cos. Meanwhile, an unprecedented number of businesses are building Intranet computer networks that allow employees to access company information when out of the office or swap data between offices. Such access and transmission of large amounts of data requires more capacity as well. ''We can barely keep up with capacity demand in the marketplace,'' said Brian Brewer, senior vice president, business marketing at MCI Communications Corp., the No. 2 U.S. long-distance phone company. The executives said companies that make hardware or software that boost capacity of phone and data networks, such as Cisco Systems Inc., will see increased demand for their wares. Several companies are already building new networks designed to transmit data at high speeds, such as Qwest Communications International Inc., GST Telecommunications Inc. and Williams Cos.
