| 12/08/11 | DOCSIS Light Sleep Mode | A new operational mode for DOCSIS equipment, which is aimed at reducing power consumption of cable modems during periods of very low data throughput. |
| 12/08/11 | Set-top energy reduction through DSG one-way mode | Set-tops systems are designed with an underlying assumption that the set-top is always actively listening to the network. A consideration in reducing set-top energy consumption is devising a means by which the set-top can maintain this one-way, receive-only, level of network connectivity at the lowest level of energy consumption. The DOCSIS Set-top Gateway (DSG) defines a one-way mode of operation in which the up-stream transmitter is disabled and the set-top remains tuned to and listens to the DOCSIS downstream channel. |

| 10/27/11 | Preventing Interference In Simultaneous RF Over Glass Transmissions | If two optical transmitters with the same wavelength transmit at the same time and if their wavelengths are close, optical beat interference occurs. This can be avoided by the CMTS performing testing for interference between optical transmitters, and the CMTS scheduler thereafter avoids simultaneous transmissions between units that are capable of interference. |
| 10/27/11 | Method To Determine Complex Frequency Response of Downstream Cable Plant | Two signal generators are locked up to a precise time standard, one at a hub site and the other at a test site that might be a home or a tap location. The generator at the hub site is offset from the generator by a frequency, such as 30 MHz that can propagate upstream. With common command and control, both generators step their way through a frequency band that needs to be tested for complex frequency response. A mixer in the hub site mixes the received test signal with the local offset signal. This generates a signal (e.g. 30 MHz) that is sent back upstream where it is demodulated in the hub site for amplitude and differential phase response. A number of methods are disclosed to provide a frequency reference for the two generators. In an alternative embodiment the demodulation can take place in the field, which saves returning the signal over the upstream band. The field demodulation can be done by synchronous conversion down to baseband I and Q, or by conversion to an intermediate frequency (IF). |

| 05/11/09 | Pre-Equalization Based Pro-active Network Maintenance Process Model for CMs Transmitting on Multiple Upstream Channels | This disclosure extends the process for analyzing the pre-equalization information to determine the gravity of the network problem and geographically isolating the source of the problem when the CM is transmitting on multiple upstream channels. Using multiple channels for upstream transmission is a feature in DOCSIS 3.0 to increase the transmission speeds. Though the preequalization parameters on multiple channels provide more comprehensive information on the spectral distortion, additional complexity is introduced in the analysis of these parameters. This disclosure and the attached paper explains the methodology used to address the frequency dependency of the micro-reflection and correlating this information across multiple channels. |
| 09/18/08 | A Method for a CM to Optimize Initial Ranging of Multiple Channels for DOCSIS 3.0 in a Plant with Strong Linear Distortion | Similar to storing the power level, this invention proposes storing the pre-equalization coefficients along with upstream channel ID in non-volatile memory at the CM This invention proposes a mechanism for DOCSIS 3.0 CMs to optimize the performance of initial ranging in a strong micro-reflection environment when multiple channels are supported by applying the pre-equalization values extrapolated from the first channel in the ranging request for the subsequent channels as long as there are no stored pre-equalization coefficients. In the case of re-initialization of the modem, if the upstream channel has not changed, using the stored pre-equalization should be given precedence over the values used for the first channel. A benefit of this proposed mechanism is to reduce the burden on the CMTS in massive outage situation as the modems are brought back on-line. An added benefit of this mechanism is in reducing the time for the cable modem to achieve high fidelity transmission in both scenarios: massive outage or normal CM initialization process. The same approach is also valid in the case when the frequency of a channel in a MD-US-SG is changed or a new channel is added to the MD-US-SG. |
| 09/11/08 | A Method for Seamless Channel Change (DCC) in a Plant with Strong Linear Distortion | This invention proposes a mechanism to effect a fast and optimized change to a new channel using DCC (DOCSIS 2.0 Dynamic Channel Change) in a strong micro-reflection environment. In this environment, the CM will be forced to perform initialization technique 2 that requires the CMTS to recalculate the pre-equalization coefficients after receiving the ranging request on the new channel and provide it in the ranging response. By deriving the pre-equalization coefficients for the new channel from the values used by the current channel, this proposal will eliminate the step where CM sends ranging request and CMTS communicates the pre-equalization coefficient using an unsolicited ranging response. The seamless approach defined in this disclosure will be useful in supporting business services where stringent SLA requirements are placed. In addition, it will improve reliability and service assurance of voice services by decreasing the number of dropped calls. |
