Abstract

Systems and methods by which voice/data communications may occur are disclosed. In particular, systems and methods are provided with a computing system having a multi-bus structure, including, for example, a TDM bus and a packet bus. An integrated communication system is coupled to a digital telecommunications link, the communication system providing voice and data communications to a plurality of users. At least a first packet bus is coupled to one or more packet-based devices and adapted for transferring packetized data to and from the system. One or more time division multiplex (TDM) buses are coupled to one or more telephony devices. Data routing resources are provided internal to the integrated system. A network interface module couples data to and from a data router external to the integrated system. The data router external to the integrated system is coupled to the first packet bus. Data is routed via the external data router through the network interface module and coupled to data channels of the digital telecommunications link, while voice data is selectively coupled to voice channels of the digital telecommunications link.

Claims

1. An integrated communication system coupled to a digital telecommunications link having voice and data channels, the integrated communication system providing voice and data communications to a plurality of users, comprising:

at least a first packet bus coupled to one or more packet-based devices and adapted for transferring packetized data to and from the integrated communication system;

one or more time division multiplex (TDM) buses coupled to one or more telephony devices;

switching/control logic circuitry internal to the integrated communication system;

data routing resources internal to the integrated communication system; and

a network interface module, wherein the network interface module couples data to and from a LAN equipment external to the integrated communication system, wherein the LAN equipment external to the integrated communication system is coupled to the first packet bus;

wherein packetized data is transferred from a packet-based device via the LAN equipment through the network interface module and coupled to a first set of the data channels of the digital telecommunications link, wherein voice data is selectively coupled via the switching/control logic circuitry to one or more of the voice channels of the digital telecommunications link, wherein packetized data from the one or more TDM buses is coupled to a second set of the data channels of the digital telecommunications link.

2. The system of claim 1, wherein:

at a first point in time, the integrated communication system operates with the LAN equipment transferring data to a pre-designated number of channels of the digital telecommunications link;

at a second point in time, the integrated communication system determines that the LAN equipment is experiencing a problem, wherein after the second point in time the data routing resources internal to the integrated communication system begin routing data to channels of an alternate digital telecommunications link.

3. The system of claim 1 wherein the LAN equipment is a router.

4. The system of claim 1 wherein the LAN equipment includes a V.35 port, and wherein the network interface module couples data to and from the LAN equipment via the V.35 port.

5. The system of claim 1 wherein the digital telecommunications link is a WAN interface.

6. The system of claim 1 wherein the digital telecommunications link is a T-1 digital trunk.

7. The system of claim 2 wherein the problem is a fault detected via SNMP packets received by the integrated communications system.

8. A method for operating an integrated communication system coupled to a digital telecommunications link, the integrated communication system providing voice and data communications to a plurality of users, comprising:

providing at least a first packet bus coupled to one or more packet-based devices and adapted for transferring packetized data to and from the integrated communication system;

providing one or more time division multiplex (TDM) buses coupled to one or more telephony devices;

providing data routing resources internal to the integrated communication system; and

providing a network interface module, wherein the network interface module couples data to and from a LAN equipment external to the integrated communication system, wherein a data router external to the integrated communication system is coupled to the first packet bus;

wherein packetized data is transferred from a packet-based device via the LAN equipment through the network interface module and coupled to a pre-designated number of data channels of the digital telecommunications link in a clear channel mode, wherein voice data is selectively coupled via the switching/control logic circuitry to one or more of the voice channels of the digital telecommunications link.

9. The method of claim 8, wherein:

at a first point in time, the integrated communication system operates with the LAN equipment transferring data to the pre-designated number of channels of the digital telecommunications link;

at a second point in time, the integrated communication system determines that the LAN equipment is experiencing a problem, wherein after the second point in time the data routing resources internal to the integrated communication system begin routing data to channels of an alternate digital telecommunications link.

10. The method of claim 8 wherein the LAN equipment performs a routing function.

13. The method of claim 8 wherein the digital telecommunications link is a T-1 digital trunk.

14. The method of claim 9 wherein the problem is a fault detected via SNMP packets received by the integrated communications system.

15. A method for operating an integrated communication system coupled to a digital telecommunications link having voice and data channels, the integrated communication system providing voice and data communications to a plurality of users, comprising:

providing at least a first bus coupled to one or more packet-based devices and adapted for transferring packetized data to and from the integrated communication system;
