Abstract

Speech telephones are incorporated in a LAN, and, for example, when a voice telephone 5 communicates with another voice telephone 8, call control is performed through exchange of information between a PC 1 and a PC 4, juxtaposed with the voice telephones, respectively, via a LAN hub 10, a LAN switching unit 50, and a LAN hub 20. Speech data of the respective telephones 5, and 8 are packetized in the data block of a MAC frame by concentrators 30, and 40 for voice telephones, respectively, and relayed to LAN-SW interfaces 30a, and 40a. Frames having a function of absorbing fluctuation are applied to the data block of the interfaces 30a and 40a. Respective voice data packetized according to the MAC address of the MAC frame are delivered to the voice telephones 5, and 8, respectively, via the LAN switching unit 50, and the concentrators 30, and 40 for voice telephones.

Claims

1-9. -9. (canceled)

10. A concentrator for voice telecommunication, apparatus comprising:

a central processing unit; and

a local area network interface for performing transmission and reception of data with the central processing unit and wherein the digital voice data, analog voice data or call control data received from the at least one voice telecommunication apparatus is converted into transmission control protocol—

internet protocol packets or user datagram protocol—

internet protocol packets, and the transmission control protocol—

internet protocol packets are transmitted and received via the local area network interface.

11. A telecommunication apparatus for voice telecommunication apparatus in a local area network including a plurality of local area network equipment, the telecommunication apparatus comprising:

at least one local area network interface connected to the local area network equipment;

a central processing unit;

a set of voice telecommunication apparatus interfaces adapted to receive and transmit at least one of digital voice data, analog voice data or call control data between the central processing unit and at least one voice telecommunication apparatus, wherein the central processing unit is adapted to convert at least digital voice data, analog voice data or call control data into transmission control protocol/internet protocol packets or user datagram protocol packets to the at least one local area network interface.

12. A method of communication over a local area network, comprising:

receiving and transmitting digital voice data, analog voice data or call control data between a voice telecommunication apparatus interface and a voice telecommunication apparatus;

receiving and transmitting the digital voice data, analog voice data or call control data between the voice telecommunication apparatus interface and a central processing unit;

converting the digital voice data, analog voice data or call control data into internet protocol packets or media access control frames with the central processing unit; and

transmitting the internet protocol packets or media access control frames from the central processing unit to a local area network interface.
