    摘要: In a particular embodiment, a method is disclosed that includes receiving data related to a customer premise equipment (CPE) device and determining an impedance mismatch between a transmission line and the CPE device based on the received data. The method further includes initiating removal of a source of the impedance mismatch in response to determining the impedance mismatch.

    摘要: An equivalent working length (EWL) determinative system (11) for use in a digital subscriber line (DSL) telecommunication network (10) is provided. The EWL system (11) includes a DSL circuit (32) having a customer site (14) with customer premises equipment (30). The customer premises equipment (30) receives and transmits communication signals and generates a first attenuation signal in response to the communication signals. A remote terminal (20) forms a loop (31) with the customer site (14) and has a loop length. The remote terminal (20) includes a remote terminal transceiver (40) that is in communication with the customer premises equipment (30). A main controller (37) is electrically coupled to the customer premises equipment (30) and determines an EWL of the loop (31) in response to the first attenuation signal. A method of performing the same is also provided.

    摘要: Apparatus, methods and articles of manufacture to predict vectored digital subscriber line (DSL) performance gains are disclosed. A disclosed example method includes determining a model coefficient of a noise-to-margin ratio (NMR) model from performance data measured for a DSL subscriber loop prior to provisioning of vectoring for the DSL subscriber loop, computing, using the model coefficient, a first NMR value with disturbers enabled and a second NMR value with disturbers disabled, and estimating an expected vectoring performance gain for the DSL subscriber loop based on the first and second NMR values.

    摘要: Example methods, apparatus and articles of manufacture to allocate ports to vectored digital subscriber line (DSL) groups are disclosed. A disclosed example method includes obtaining data representative of a statistical distribution of service penetration for a non-vectored DSL service, estimating an expected vectored DSL group size from the data, and configuring a DSL access multiplexer (DSLAM) to reserve a number of ports of the DSLAM for a vectored DSL group based on the expected vectored DSL group size.
