Described is a method for performance estimation of a communication device. The method comprises: executing active probing to determine active probing data; reading operational data which includes data related to channel and its noise condition and counter values related to user data traffic between the communication device and another communication device, wherein the operational data is relevant to the current settings of the communication device; and training a performance estimation algorithm for the communication device according to the active probing data and the operational data.

Systems, devices, and techniques are disclosed for maintaining service availability. Files including code written using a Domain Specific Language (DSL) for network security may be received. A knowledge graph including connections between services may be generated from the code written using the DSL in the files. A service that will have an availability issue may be determined based on the connections between services in the knowledge graph. The service that will have the availability issue may be replicated. The replication of the service that will have the availability issue may occur before the service has the availability issue.

Upon detection of a trigger, such as the exceeding of an error threshold or the direction of a user, a diagnostic link system enters a diagnostic information transmission mode. This diagnostic information transmission mode allows for two modems to exchange diagnostic and/or test information that may not otherwise be exchangeable during normal communication. The diagnostic information transmission mode is initiated by transmitting an initiate diagnostic link mode message to a receiving modem accompanied by a cyclic redundancy check (CRC). The receiving modem determines, based on the CRC, if a robust communications channel is present. If a robust communications channel is present, the two modems can initiate exchange of the diagnostic and/or test information. Otherwise, the transmission power of the transmitting modem is increased and the initiate diagnostic link mode message re-transmitted to the receiving modem until the CRC is determined to be correct.

Embodiments relate to a method for detecting a broken binder in an access network including a plurality of telecommunication lines grouped in respective binders, executed by a detection device, including identifying a plurality of telecommunication lines for which a transmission interruption has been detected within a given time period obtaining line data associated with the respective identified telecommunication lines, for respective pairs of identified telecommunication lines, determining a virtual distance between the two telecommunication lines, in function of the associated line data, determining at least one cluster of telecommunication lines in function of the virtual distances, and detecting a broken binder in function of the determined at least one cluster.

A method for estimating, in a broadband communication system including an access network and a plurality of broadband communication lines associated with the access network, a sustainable speed that can be sustained by a selected broadband communication line of the plurality of lines.

The present invention relates to an apparatus for reverse power feeding in accordance with communication line environments and a method thereof, which measure line resistance (e.g., a difference in impedance depending on a distance between a customer premise (CP) and a distribution point (DP)) of a communication line (e.g., a twisted pair copper wire) connected to a distribution point at a customer premise and reflect the measured line resistance to perform stable power feeding to the distribution point.

A method of operating a captioned telephone, comprising storing analog test data in a captioned telephone memory, dialing a telephone number to a relay gateway, connecting to the relay gateway over a communication network and performing a test of the communication network quality using the test data to determine if the network is sufficient to carry analog data, the test including at least one of transmitting the test data to the relay gateway and receiving test data from the relay gateway via the communication network, wherein the network is one of a POTS network and a VOIP network.
