Cox Communications will test the delivery of telephone services over its cable TV system in San Diego. Telephone services will include direct-dial local and long-distance calling and custom calling features. ``Our goal is to provide a viable alternative to the traditional providers of both wireless and wireline communications,'' said David Woodrow, Cox Communications' senior VP for Broadband Services. ``This new model of communications, offering a wide variety of video and telecommunications services packaged together, will be a unique marketplace offering.'' Initial testing begins later this month.
