PRODUCT DESCRIPTION
The ChannelWorks product provides distributed, high speed, network
bandwidths for sites in metropolitan areas, using existing public cable
plants. It is a cost-effective alternative to existing and planned telephone
company offerings. Because the ChannelWorks product can be used on the full
spectrum of public CATV networks, channel assignments will accommodate
potential users in all metropolitan areas.
BENEFITS
At a fraction of the cost of today's point-to-point communications
solutions, this extended Ethernet LAN connectivity service incorporates the
ChannelWorks bridging technology, network planning, and network management
services along with a CATV infrastructure to offer you a true information
utility service.
The ChannelWorks product is based on existing standards, providing you with
investment protection and complementing Digital's other networking products.
The high speed, distributed network technology, combining SNMP network
management with easy configuration and maintenance, is familiar to most
network managers.
