## Abstract

A system for testing multiple cable modem/eMTA devices independently and simultaneously using different types of device probes is disclosed. The system includes real-time, bi-directional/asynchronous communication and interaction between the system components.

## Claims

### Claim 1

A system for testing a plurality of devices, the system comprising:
a universal tester;
at least one test controller;
a plurality of sets of testing probes;
a plurality of web sockets;
wherein,
the plurality of devices includes a plurality of cable modem/eMTA devices;
the universal tester is enabled for communication with a platform independent user interface through the plurality of web sockets;
the plurality of sets of testing probes comprising:
a plurality of LAN probes for testing corresponding LAN interfaces of a cable modem/eMTA device of the plurality of cable modem/eMTA devices;
at least one FXS probe for testing a corresponding FXS interface of the cable modem/eMTA device of the plurality of cable modem/eMTA devices;
at least one WLAN probe for testing a corresponding WLAN interface of the cable modem/eMTA device of the plurality of cable modem/eMTA devices;
at least one MoCA LAN probe for testing a corresponding MoCA LAN interface of the cable modem/eMTA device of the plurality of cable modem/eMTA devices;
at least one NCS/IMS probe for testing a corresponding DOC SIS WAN interface of the cable modem/eMTA device of the plurality of cable modem/eMTA devices;
at least one provision probe for testing the corresponding DOCSIS WAN interface of the cable modem/eMTA device of the plurality of cable modem/eMTA devices;
at least one WAN probe for testing the corresponding DOCSIS WAN interface of the cable modem/eMTA device of the plurality of cable modem/eMTA devices; and
the plurality of web sockets enable real-time bi-directional and asynchronous communication between the platform independent user interface and the universal tester for simultaneously testing the plurality of devices by the universal tester.

### Claim 2 (depends on 1)

The system of claim 1, further comprises a MoCA LAN bridge.

### Claim 3 (depends on 1)

The system of claim 1, further comprises a cable modem termination system.

### Claim 4 (depends on 1)

The system of claim 1, further comprises a splitter.

### Claim 5 (depends on 1)

The system of claim 1, wherein the real-time bi-directional and asynchronous communication of the plurality of web sockets enable a user to control the testing of the plurality of devices simultaneously but asynchronously and independently of each other using the universal tester.

### Claim 6 (depends on 1)

The system of claim 1, wherein the plurality of devices installed in the universal tester for purposes of simultaneous testing comprise a set of disparate devices.

### Claim 7 (depends on 1)

The system of claim 1, wherein the plurality of devices installed in the universal tester for purposes of simultaneous testing comprise a set of similar devices.

### Claim 8 (depends on 1)

The system of claim 1, further being adaptable to augmenting the test controller, the plurality of web sockets, the user interface and the plurality of sets of testing probes to accommodate testing of new types of devices.
