초록 ▼

A system and method for isolating data messages received from subscribers in a CATV system are disclosed. The system includes a spectrum parallel router which receives data messages in the return spectrum of a service line at a service site. A switch at the service site directs data messages to service lines coupled to the site which have destination addresses corresponding to one of the service lines. Data messages not having a destination address corresponding to one of the service lines are provided to a transmitter for transmission to the next higher level of the CATV network over a return cable. Each service site has its own return cable which may be coupled to a distribution hub or a headend.

대표청구항 ▼

What is claimed is: 1. A method for communicating data messages in a CATV system comprising the steps of: receiving data messages from subscribers coupled to service lines extending from a service site in a CATV system; routing said data messages received from a subscriber coupled to one of said service lines extending from said service site to another subscriber coupled to one of said service lines extending from said service site; and placing said data messages having a destination address not corresponding to one of said subscribers coupled to one of said service lines extending from said service site onto a spectrum of a return cable coupled to a headend of said CATV system so that said data messages for said subscribers not coupled to one of said service lines extending from said service site in a CATV system are isolated from said data messages being sent to said subscribers coupled to one of said service lines extending from said service site in said CATV system.
