A communications network is disclosed and includes a broadband communication line having a first derived voice channel and a second derived voice channel, wherein the first and second derived voice channels are established as a function of an available bandwidth associated with the broadband communication line. The communication network further includes a residential gateway in communication with the broadband communication line. The residential gateway includes a switch, a network interface device in communication with the switch, and wherein the switch is configured to select at least one of the first or second derived voice channels for voice communication over the broadband communication line as a function of the available bandwidth.

System and network for deriving voice channels on a broadband communication line

Wide area communication networking

A method of providing digital data services between a communications service provider and a customer site over a communications loop may include predicting a level of performance of the communications loop without coupling a modem to the communications loop at the customer site to provide a predicted level of performance of the communications loop. The communications loop may be qualified for an initial qualified level of digital data service based on the predicted level of performance of the communications loop. After qualifying the communications loop, digital data service may be provided over the communications loop at the initial qualified level using a modem coupled to the communications loop at the customer site, and a measured level of performance of the communications loop may be obtained based on data communicated between the communications service provider and the modem over the communications loop. The measured level of performance may then be compared with the predicted level of performance. Related systems and computer program products are also discussed.

Systems and methods are disclosed for providing network testing. The disclosed systems and methods may include connecting to at least one element within a network. Furthermore, the disclosed systems and methods may include performing a test on the network through at least one element. The test may be associated with at least one addressable device connected to the network. In addition, the disclosed systems and methods may include analyzing data associated with the test.

Methods and systems for providing end-to-end testing of an IP-enabled network

Systems and methods for modeling a subscriber network experience. In one embodiment, a method includes the act of receiving a plurality of subscriber metrics associated with a subscriber to an access network. The method also includes the act of modeling the subscriber experience by applying at least one transformation to the plurality of subscriber metrics to produce a set of subscriber experience data. The metrics measure quality of service for a subscriber experience with the access network. Each element of the subscriber experience data quantifies an aspect of the subscriber experience.

A wide area communications network or simply a communications network is includes a broadband communication line having a first voice channel and a second voice channel, wherein the first and second voice channels are derived channels. The communications network further includes a residential gateway in communication with the broadband communication line. The residential gateway includes a network switch, a network interface device in communication with the network switch wherein the network switch is configured to select at least one of the first or second voice channels for voice communication over the broadband communication line.

A telecommunication system includes a digital switch, a local loop coupling the digital switch to a subscriber location, wherein a segment of the local loop includes copper twisted pair and wherein an asymmetrical digital subscriber line is carried by the local loop, the asymmetrical digital subscriber line including a plurality of data packets capable of carrying a plurality of derived digital telephone lines. The telecommunication system further includes a subscriber unit coupled to the asymmetrical digital subscriber line. The subscriber unit monitors the content of at least one of the plurality of data packets, receives an off-hook signal in response to an action of a user, and initiates a first derived digital telephone line of the plurality of derived digital telephone lines in response to the off-hook signal. A telephone communication system including an analog telephone providing a plain old telephone service (POTS) analog voice channel on a subscriber loop with a digital data line sharing the same subscriber loop. In addition to the analog voice line, the digital data line provides an additional digital voice channel for placing telephone voice calls.
