CableLabs Invention Disclosures
This listing contains published invention disclosures made by Cablelabs. This public listing is intended to serve as a "printed publication" as defined under 35 U.S.C. 102.
| Date | Title | Summary |
| 06/30/08 | Pre-Equalization Based Pro-active Network Maintenance Process Model | This disclosure describes process for analyzing the pre-equalization information to determine the gravity of the network problem and geographically isolating the source of the problem. Even though this embodiment details the pro-active maintenance process using pre-equalization parameters and DOCSIS defined parameters, the methodology can be applied to other impairments along with their related network health metrics. |
| 06/30/08 | A Simple Algorithm for Fault Localization Using Naming Convention and Micro-reflection Signature | This invention proposes a simple algorithm to determine the location of the fault after calculating the micro-reflection signature and applying the naming convention described in previous disclosures. A manifestation to implement this algorithm is described by defining an XML schema and XPath queries. This algorithm enables efficient processing of large numbers of CMs thus facilitating scalability and automation. |
| 01/30/08 | High Availability Mechanism for Modular CMTS Systems | This invention provides a way to offer high availability with M-CMTS systems. It provides 1+1 redundancy for M-CMTS Cores and n+1 redundancy for EQAMs by exchanging status messages and performing health checks on various components. |
| 01/30/08 | DOCSIS Timing Interface (DTI) Test Dongle | This device allows a user to connect an oscilloscope to an M-CMTS core device without using scope probes. |
| 01/11/08 | DT Box: DOCSIS Test Box | A diagnostic device with multiple applications in CATV environments; can be used to simulate a standard DOCSIS Cable Plant and provides a means for capturing and analyzing specific types of Radio Frequency signals. The tool is particularly adapted to sensing bursty traffic on coaxial networks and providing triggering signals to RF measurement equipment. |
| 01/11/08 | A method/architecture for enabling 2-way cable services to home networked IP-STBs with OCAP, but w/o cable modem and tuner | This invention describes a method/architecture for extending traditional 2-way cable services to OCAP-enabled IP-STBs (w/o cable modem and tuner) via a 2-way gateway device. |
