The Comcast Home Networking service package offers enhanced speeds, a wireless home gateway device (integrated cable modem and router), and networking gear for up to five devices in the home. Users can connect PCs or broadband-capable devices, and households can share access to the Internet, files, CD drives and printers across the network. In addition, users can access speeds of up to 4 Mbps downstream and 384 kbps upstream for seamless high-speed access across multiple devices.

The Hybrid cable modem may allow an attacker to anonymously reconfigure the modem. The attacker exploits a design flaw in the HSMP configuration protocol. There is no authentication requirement when making configuration requests through the HSMP protocol. The UDP-based protocol is easily spoofed which allows an attacker to easily make configuration changes anonymously.

In a Declaratory Ruling adopted today, the FCC concluded that cable modem service is properly classified as an interstate information service and is therefore subject to FCC jurisdiction. The FCC determined that cable modem service is not a "cable service" as defined by the Communications Act. The FCC ... said that cable modem service does not contain a separate "telecommunications service" offering and therefore is not subject to common carrier regulation.

The interoperability effort got another boost during the Western Show when AT&T Network Systems, Hewlett-Packard Company, Hybrid Networks Inc. and Intel Corporation announced their intention to jointly develop open cable modem specifications by the end of 1995. Christened the Broadband Link Team (BLT), the four-member coalition said that once a set of specifications was arrived at, they would submit them to the appropriate standards committees, cable operating companies and CableLabs for their review and recommendations.
