摘要： A system and method for multiple inputs, multiple outputs (MIMO) PSD allocation in a DSL system is disclosed. In some embodiments, the method may comprise monitoring system performance by performing a multi-ended line test (MELT), processing the MELT and allocating PSD based on at least one of system coupling power and system traffic.

摘要： An improved ADSL modem is presented. The ADSL modem in cooperation with a remote ADSL modem will exchange manufacturer identification information during initial DSL system training to establish a DSL communication link. The improved ADSL modem may comprise a memory device containing system parameters and operational algorithms previously determined to maximize DSL link performance between ADSL modems manufactured by different vendors. The improved ADSL modem is well suited for central office applications as it provides a solution for optimizing system performance that is transparent to remotely located ADSL modems. An ADSL modem in accordance with the present invention may comprise a digital signal processor and a memory device configured to store appropriate system parameters and operational algorithms that provide an optimized DSL communication link once applied during system initialization. The present invention also provides a method for optimizing DSL system performance. The method can be described by the following steps: supplying a default manufacturer identification for a remote modem at a master modem; applying appropriate system parameters and algorithms in response to the default manufacturer identification; initializing DSL system start-up training; receiving the actual manufacturer identification for the remote modem; determining if the current system parameters and algorithms are suitable for a DSL link with the actual manufacturer; adjusting training parameters and algorithms; restarting training when required; and establishing the DSL link.

摘要： A method and system are provided for preventing data loss in a VoIP system. In particular, during a VoIP call, it is determined whether incoming ringing on a POTS line causes an unacceptable level of signal loss or errors. If so, for subsequent VoIP calls, the CO handling calls to the POTS line is instructed to either answer each call with a busy signal or automatically forward calls to the POTS line to the VoIP line or other selected telephone. Calling returns to normal upon ending of the VoIP call. In this manner, incoming ringing on the POTS line does not result in call dropping or lengthy retraining processes.

摘要： A method and system for device mobility using application label switching in a mobile communication network are disclosed. In one embodiment, the method comprises establishing an application session involving a first computing device, a second computing device, a client application and a server application. The application session includes, a first unbreakable session between the client application and the first computing device, a second unbreakable session between the server application and the second computing device, and one or more breakable sessions between the first computing device and the second computing device. The first unbreakable session and the second unbreakable session are maintained when the one or more breakable sessions terminate. One or more new breakable sessions are created when the one or more breakable sessions terminate. The application session is reestablished with the one or more new breakable sessions, the first unbreakable session and the second unbreakable session.
