Abstract

A system for collecting data from a communications network includes customer premises equipment (“CPE”) for monitoring and storing response data. A CPE data collection module uses a Web-based service to collect information from the CPE and process the information to determine line quality and any errors that may exist on either the WAN side or the LAN side of the communications network, and further determine the root cause based on built-in business rules for trouble shooting customer service. The CPE conducts per-tone diagnostics on the WAN side of the communications network and obtains WAN side data. The CPE obtains response data from devices on the LAN side. Both WAN side data and LAN data may be transmitted substantially in real-time or stored and transmitted periodically to the CPE data collection module upon requests originated from the CPE data collection module.

Claims

1. A system for data collection in a communications network, the system comprising:

a CMS server in communication with a CPE data collection module and a CPE device, the CMS server configured to;

receive a plurality of CPE diagnostic parameters from the CPE device; and

transmitting, via a first data path through a firewall, the plurality of CPE diagnostic parameters to the CMS server, wherein the CPE diagnostic parameters are selected from the group consisting of per-tone attenuation parameters indicative of per-tone attenuation of a connection between the CMS server and the CPE device, downstream code violation parameters, upstream code violation parameters, and noise condition parameters indicative of a signal to noise ratio of the connection between the CMS server and the CPE device.

2. The system of claim 1, wherein the CPE device is integrated with a DSL modem.

3. The system of claim 1, wherein the CMS server communicates with the CPE data collection module through a web-based service.

4. The system of claim 1, wherein the CPE diagnostic parameters are collected and recorded substantially in real-time.

5. The system of claim 1, wherein the CPE device is connected in a local area network that includes a plurality of CPE.

6. The system of claim 1, further comprising:

a CPE identification database accessible by the CPE data collection module for retrieving a stored user parameter associated with the CPE device.

7. The system of claim 6, wherein the CMS server provides a function selected from the group consisting of:

a load balancer;

an application server; and

a database server.

8. The system of claim 7, further comprising a CPE activation system for enabling and disabling the CPE device.

15. The system of claim 1, wherein the communications network includes a LAN side and a WAN side separated by the firewall and wherein the CMS server and the CPE data collection module reside on the WAN side and the CPE device resides on the LAN side.

9. A method of operating a first customer premise equipment (CPE) configured to facilitate communication between one or more devices on a LAN side of a network and a WAN side of the network, the method comprising:

collecting and storing by the first CPE first response data, the first response data including WAN side per tone attenuation data;

processing by the first CPE a digital certificate from a content management server to determine whether the first CPE should transmit the first response data; and

transmitting by the first CPE the first response data to a CPE data collection module.

10. The method of claim 9, further comprising:

collecting and storing by the first CPE second response data, the second response data regarding functionality of a second CPE.

11. A gateway operating comprising:

an input interface for connecting to a LAN side of a network;

a transceiver in communication with the input interface for sending and receiving a first plurality of signals over the input interface, the first plurality of signals containing user-generated data;

a first output interface for connecting to a WAN side of the network and for providing an Internet connection to a first CPE;

a processor for conducting diagnostic tests to obtain response data, the response data indicative of a signal-to-noise (SNR) ratio of at least a portion of the WAN side of the network;

a memory for storing the response data;

a second output interface for providing telephone signals to a second CPE;

a third output interface for providing the Internet connection to a plurality of CPE, the plurality of CPE in addition to the first CPE;

wherein the response data is sent to a CPE data collections module substantially in real-time.

12. The residential gateway of claim 11, wherein the processor is enabled to conduct per-tone attenuation diagnostics on a local loop to result in per-tone diagnostic data stored in the memory.

13. The residential gateway of claim 12, wherein in response to an operator input, the processor is enabled to initiate sending the per-tone diagnostic data to a CPE data collection module.

14. The residential gateway of claim 13, wherein the residential gateway is enabled for communicating with a content management server using TR-069 protocol.
