First Claim
Patent Images
1. A digital packet data network for transporting packetized voice and data signals in the local loop between a central office switch and a plurality of local users, comprising:
- a first converter located at the central office for converting the voice signals into voice packets and data signals into data packets, the first converter operable to provide priority processing treatment to voice packets over data packets;
a second converter located remotely from the central office and in the vicinity of the local users for converting the voice packets into voice signals and the data packets into data signals, the second converter operable to provide priority processing treatment to voice packets over data packets; and
a packet-switched network connected between the first and second converters for transporting the voice and data packets to and from the plurality of local users.

Abstract
A digital packet access network for transporting voice and data signals in the local loop between a central office location and a plurality of remote local users. The network architecture may also include: (1) a dual-pipelined structure for separately transporting the voice and data signals; (2) a mechanism for prioritizing the transport of the voice signals; or (3) a method of synchronizing the timing of the voice signals to a telephone switch.
