First Claim
1. A signal transmission method of a closed network constructed from at least one telephone exchange (10) and a key telephone system that is composed of a plurality of telephones (20), the method comprising the steps of:
- connecting each telephone (20) to the telephone exchange (10);
employing each telephone (20) as a node for connection to a network device (30) so as to form the closed network for voice, data and video transmission; and
converting voices received from a first one of the plurality of telephones (20) to the form of voice packets;

Abstract
A digital closed network is constructed from a telephone exchange (10) and a plurality of telephones (20), wherein each telephone (20) is further for connection to a network device (30), such as a computer, hub, network printer etc. Over the closed network, data and video information are transmitted in the form of packets. Moreover, communicating voice signals are converted to the form of voice packets by the telephones (20), whereby the superior transmission quality is obtained. Furthermore, the transmission priority among the voice, data and video packets is controllable in the closed network, thus when there is a great quantity of packets being transmitted, the voice packets still possess high real time transmissions.
