What are broadband services

Original Bell System Definition

“A broadband channel is a communications channel having a Bandwidth greater than a voice-grade channel, and therefore capable of higher-speed data transmission.”

1996 Telecom Reform Act

Broadband services are capable of carrying “high-quality” voice, data, graphics, & video.

CCITT definition

A service requiring transmission channels capable of supporting rates greater than 1.5 Mbps or primary rate in ISDN or T1 in digital terminology.

What Are Broadband ServicesPractical Definitions•Residential

–Currently means DSL, cable modem, or high speed wireless–Today’s services are web access, work-at-home, & steaming audio(Napster, etc)–Tomorrow, next generation video will be the killer app”(Son of Napster?)

•Business–Data, data, & data–Today generally 1.5Mbps and up–Tomorrow MUCH MORE than 1.5Mbps(100Mbps?)
