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.

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.

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.
摘要:
A system and method to perform double-ended measurements of a network is provided. The system includes a test device that makes measurements at the customer end and a portable computing device that interfaces with the test device, a customer gateway and database at a network location to analyze the data and determine a performance metric of the network.
