Abstract

A communication system is comprised of a computer system connected to a LAN, a local area communications system (LAX) connected to the LAN, peripheral communications devices connected to the LAX, apparatus for controlling communications between the devices via the LAX under control of programs resident in a computer of the computer system, the controlling apparatus comprising a database for storing server system configuration data, a peripheral driver, a call control for controlling the peripheral driver and accessing application programs and the system configuration data, and a protocol converter for passing control and data messages in manners proprietary to each peripheral communications device from and to the peripheral communications devices via peripheral drivers and to and from a variety of standard and non-standard application programs stored in the computer system.

Claims

1. A communication system comprising:

(a) a local area network (LAN),

(b) a computer system connected to the LAN including means for storing and processing applications programs, one of said applications programs being a program for controlling a communications device,

(c) a telecommunications server connected to the LAN including means for controlling connection of communications peripheral devices,

(d) communications devices connected to said server,

(e) said server comprising means for receiving a request for service from one of the communications devices, for passing a message to said computer system via the LAN, for receiving control messages resulting from said computer system processing a program for controlling a communications device and for controlling at least one of connections and operation of said communications device dependent on the character of said control messages, and having (i) a database for storing server system configuration data, (II) a peripheral driver, (iii) a call controller for controlling the peripheral driver and accessing application programs and the system configuration data, and (iv) a protocol converter for passing control and data messages in manners proprietary to each peripheral communications device from and to said peripheral communications devices via peripheral drivers and to and from a variety of standard and non-standard application programs stored in said computer system; and

(f) a system management means for initializing the server and configuring the server in accordance with data stored in the database.

2. A communications system as defined in claim 1, wherein the call controller communicates with external data interface means via the LAN.

3. A communications system as defined in claim 1 including means for storing various server control applications programs in the server for controlling the call controller and the peripheral driver.

4. A communications system as defined in claim 1, wherein the system management means comprises a maintenance control program, an administration control program, a billing control program and a traffic statistics program for respectively maintaining, advertising, billing and gathering and analyzing statistically the operation of the server.

5. A communications system as defined in claim 1 wherein data gathered and generated by the system management means is stored in the database.

6. A communications system as defined in claim 1 in which the means for controlling connection of the communications devices is a master controller operating under control of messages provided by a peripheral driver controller.

7. A communications system as defined in claim 6, wherein the master controller interfaces the peripheral drivers directly.

8. A communications system as defined in claim 6, wherein the master controller is comprised of the peripheral drivers.

9. A communications system as defined in claim 1 in which the means for controlling connection of the communications devices is a master controller operating under control of messages provided by the management means.

10. A communication system as defined in claim 1 wherein the server is distributed in several locations, the server at one location being defined as a master and the servers at the other locations being defined as slaves, the master and slaves being interconnected by LANS and wide bandwidth data transmission media, the master and each slave having a protocol converter and master controller, the master having said system management means, peripheral devices being connected to each of the master and slaves, signals to and from the peripheral devices of each of the master and slaves being translated by a protocol converter of the associated master or slave, connection of the peripheral devices to each other or to others via a LAN or data transmission line being controlled by a master controller of the associated master or slave, and said applications programs for operation of all of the master and slave being stored in association with the master for accessing thereof by the system management means and control of all of said master and slaves.

11. A system as defined in claim 1, in which at least one of the communications devices is an interface to a public switched network.

12. A system as defined in claim 1, in which said communications devices are comprised of at least one of a computer interface, a video interface, a fax modem, a data modem, an electronic mail system and a voice mail system.

13. A system as defined in claim 12, in which at least one of the communications devices is an interface to a public switched network.

14. A communication system comprising a computer system connected to a LAN, a local area communications system (LAX) connected to the LAN, peripheral communications devices connected to the LAX, means for controlling communications between said devices via the LAX under control of programs resident in a computer of said computer system;

said controlling means comprising (i) a database for storing server system configuration data, (ii) a peripheral driver, (iii) a call controller for controlling the peripheral driver and accessing application programs and the system configuration data, and (iv) a protocol converter for passing control and data messages in manners proprietary to each peripheral communications device from and to said peripheral communications devices via peripheral drivers and to and from a variety of standard and non-standard application programs stored in said computer system; and

a system management means for initializing the LAX and configuring the LAX in accordance with data stored in the database.

15. A system as defined in claim 14, wherein the LAX is connected to a public switched network for receiving calls from and transmitting calls to, the public switched network.

16. A system as defined in claim 14, integrated into a PABX.
