This brings GTE Internetworking's DiaLinx coverage in major metropolitan areas to nearly 400 dial-up locations. The availability of ISDN capability provides greater flexibility to the DiaLinx service for better performance and increased cost savings to the corporate customer. ISDN will initially be made available in over 100 major metropolitan areas, with broad coverage provided by the end of the year.
