Abstract
Abstract A telecommunications system and method for use on aircraft and other vehicles. One or more token ring local area networks are utilized to provide a telecommunications link between a plurality of telephone units and a telephone data signal router circuit which, in turn, is coupled to a CEPT E1 bus and provides telecommunications data signals over the CEPT E1 bus to a cabin telecommunications unit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
258 words
A method for distributing telecommunications voice data within an aircraft or other vehicle, said method comprising the steps of: generating an analog audio voice signal; converting said analog audio voice signal to a digital data signal; separating said digital data signal into a plurality of bytes of digital audio data and storing said digital audio data bytes in a first memory; retrieving sets of said digital audio data bytes from said first memory and delivering Said sets of said digital audio data bytes to a first local area network; transmitting said sets of said digital audio data bytes over said first local area network to a first telephone data routing circuit; storing said sets of said digital audio data bytes in a second memory electronically coupled to said first telephone data routing circuit; retrieving said sets of said digital audio data bytes from said second memory and delivering said sets of said digital audio data bytes to a second local area network; transmitting said sets of said digital audio data bytes over said second local area network to a second telephone data routing circuit; storing said sets of said digital audio data bytes in a third memory electronically coupled to said second telephone data routing circuit; retrieving said sets of said digital audio data bytes from said third memory, formatting said sets of digital audio data bytes for transmission over a serial data communications bus; and delivering said sets of said digital audio data bytes to said serial data communications bus for transmission to a cabin telecommunications unit.
Claim 2
Independent Claim
