Methods, systems, and apparatus for diagnosing and optimizing an Internet Protocol television (IPTV) network are disclosed. In one aspect a method includes receiving a network address of a device; detecting a network topology associated with the device based on the network address of the device; identifying a configuration parameter setting associated with the network topology that is outside of a range of acceptable configuration parameter settings for the network topology; and providing output specifying the configuration parameter setting that is outside of the range of acceptable configuration parameter settings.

Systems and methods for wireless management access to a telecommunication device are provided. A portable device, such as a tablet, smartphone, etc., can be used to access a network device, such as a telecommunication device, by accessing a wireless access module of the telecommunication device using any desired wireless technology. When the portable device is in proximity to the telecommunication device the presence of the portable device may be detected, causing an attempted wireless communication between the portable device and the wireless access module. The portable device may provide various security information to the wireless access module that may be verified before access to the telecommunication device is granted. If the portable device is verified it may be authorized for wireless communications with the telecommunication device, including receiving an identifier for the telecommunication device.

The present disclosure generally pertains to systems and methods for provisioning nodes of a packet network. Rather than requiring a user to individually set the configuration parameters of each node to achieve a desired behavior, the user is presented with options of various predefined network behaviors and/or the option of customizing a network behavior, such as a queuing, scheduling, or shaping profile, and each node is configured to automatically provision its configuration parameters to implement the desired behavior. Information is passed from node-to-node so that each node can automatically provision its settings to implement such behavior. Thus, the network is automatically provisioned thereby facilitating the provisioning process. Automatic provisioning also helps to ensure a correct network configuration. Indeed, since the provisioning is automatic, at least some manual provisioning errors may be prevented.

A communication system extending Ethernet Operation and Management (OAM) Loopback Message (LBM) and Loopback Replay (LBR) functionality into a time division multiplexing (TDM) domain has a first interworking function (IWF) of an Ethernet network that transmits an Ethernet Operation and Management (OAM) Loopback Message (LBM) having a first type length value (TLV) field. The first IWF controls the first TLV field to indicate that a connectivity test is to extend beyond the Ethernet network. The communication system further has a second IWF of the Ethernet network that receives the Ethernet OAM LBM and interprets the first TLV field. In addition, the second IWF performs a TDM connectivity test across a TDM connection in response to the Ethernet OAM LBM and based on the first TLV field and transmits a reply for the Ethernet OAM LBM to the first IWF, the reply prompted by the LBM and comprising data based on the TDM connectivity test.

A communication system for propagating time division multiplexing (TDM) fault notifications has a first interworking function (IWF) of a packet network and a second IWF of the packet network. The second IWF detects a TDM fault of a TDM network and transmits continuity check messages (CCMs) to the first IWF. Further, the second IWF controls the CCMs in response to a detection of the TDM fault such that a TDM fault notification is propagated from the second IWF to the first IWF based on the CCMs, and the first IWF propagates the TDM fault notification to a second TDM node via a TDM signal.

A repeater for regenerating signals communicated along a telecommunication line uses a constellation providing a sufficiently high constellation density to ensure that regenerated signals are spectrally compatible. In one exemplary embodiment, such a repeater is configured to implement a method comprising the steps of: receiving first data signals from a first telecommunication line segment; demodulating the first data signals thereby recovering digital data using a constellation that provides a first constellation density; modulating second data signals with the digital data; transmitting the second data signals across a second telecommunication line segment that is bound within a cable; selecting a second constellation density for use in the modulating step such that the second data signals are spectrally compatible with other signals transmitted across a third telecommunication line segment bound within the cable, wherein the second constellation density is higher than the first constellation density.

The present disclosure generally pertains to systems and methods for discovering PME bonding groups. In one exemplary embodiment, a plurality of communication links are terminated by physical medium entities (PMEs). In this regard, each link is terminated at one end via a network PME and at another end via a remote PME at a customer premises. Each of the PMEs has a transceiver that is allowed to train during a training phase that precedes a data phase. After training, discovery of PME bonding groups is performed via data communicated over data phase control channels, which are operational while links are operational in the data phase, transmitting data using the Ethernet in the First Mile (EFM) encapsulation. For example, the control channel data may be communicated over a link-level embedded operations channel (EOC). In another example, the control channel data may be communicated using 64/65 Byte (B) code words. In another example, the control channel data may be communicated via an Ethernet operations, administration and maintenance (OAM) channel. In yet another example, the control channel data may be communicated via EFM fragment messaging.

A system includes a transceiver for communicating over a telecommunication line that is coupled to the transceiver. The transceiver comprises logic configured to measure attenuation of at least one signal transmitted across the telecommunication line. The logic is further configured to automatically select, based on the measured attenuation, a plurality of different data rates for a plurality of initialization signals communicated via the transceiver during an initialization phase that precedes a data phase.

System and method for selecting data rates of initialization signals

A transceiver comprises a communication line interface, memory, and logic. The memory stores predefined noise spectra, and the logic is configured to analyze an initialization signal received from the communication line coupled to the communication line interface during an initialization phase that precedes a data phase. The logic is configured to automatically select one of the predefined noise spectra based on the initialization signal and to combine the selected noise spectrum with the initialization signal to calculate a value. The logic is configured to perform a comparison between the value and a threshold and to make a determination, based on the comparison, whether a data signal to be communicated in the data phase will be spectrally compatible, if the data signal is transmitted at a data rate of the initialization signal. The logic is further configured to select a data rate for the data signal based on the determination thereby ensuring that the data signal is spectrally compatible.

A method, system and apparatus for decreasing the time frame synchronization and resynchronization in a data communication uses an long frame sync word formed by combining a frame sync word with stuff bits, wherein the stuff bits are necessary for timing adjustments.

In a data communication system having a channel with time-varying impairments and further having a transmitter with a precoder, a method and apparatus for updating the precoder coefficients. The method and apparatus is based on the arrangement of a duplicate precoder and correction filter in the receiver, where the correction filter generates incremental coefficients. The incremental coefficients are sent via a back channel to the transmitter and added to the current values of the precoder coefficients. The method and apparatus provide DFE-like performance and do not have the delay problems associated with DFEs.
