METHOD AND APPARATUS FOR CONVERTING SYNCHRONOUS NARROWBAND SIGNALS INTO A SONET VIRTUAL TRIBUTARY GROUP FOR COMBINING WITH BROADBAND ASYNCHRONOUS TRANSFER MODE SIGNALS IN AN INTEGRATED TELECOMMUNICATIONS NETWORK |
摘要 |
In the network of the invention, telephony and other narrow band services are provided using twisted pairs via existing fiber-in-the-loop (FI TL,)technology while the analog video and digital broadc ast video are carried over asingle coaxial cable to the customer premise. Al l customer subscriber lines are moved out of the central office and are distributed in the outside distribut ion plant via FITL technology. Data and digital video from the central office are dist ributed to a large number of field located optical network units (ONU) as ATM signals o ver optical fibers. The narrowband signals are converted to a SONET virtual trib utary group and are combined with the digital video signals for delivery to the ho me.
