  • Patent number: 5959988
    Abstract: A telecommunications switch is provided with an internal ethernet link which is connected to a group switch/time switch portion of the switch through a number of interface processors. The group switch/time switch portion functions to switch data communications among and between the subscriber lines, trunk lines and the interface processors. The ethernet link serves as a concentrator for packet data communications carried over the subscriber/trunk lines and handled by switch. The interface processors operate to selectively insert and extract packet data communications to and from the ethernet link. A connection is made via the ethernet link to an Internet access point to allow concentrated data packet communication with the Internet.
