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 remote battery replacement notification system () for a communication system includes a subscriber unit () having a battery (). An operational support system () is in communication with the subscriber unit (). The operational support system () periodically polls the subscriber unit (). A compact service node () is in communication with the subscriber unit (). The compact service node () sends a replace battery notification to the subscriber unit () when a replace battery message is received from the operational support system ().

Remote battery replacement notification system and method

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 call is routed to a wireless mobile station from a wireline network while bypassing a host mobile switching center (MSC) of the mobile station when the mobile station is registered at an MSC other than the host MSC. In particular, a service control point (SCP) in the wireline network receives a query from a tandem switch, associated with a trunk group of the host MSC, in response to an attempted termination of the call at the trunk group. Based on information from the query, the SCP retrieves registration data from a home location register of the host MSC, using IS-41 signaling. When the registration data indicates that the mobile station is registered at the alternate MSC, the SCP instructs the tandem switch to route the call directly to a trunk group of the alternate MSC, i.e., without passing through the host MSC.

Wireless direct routing service

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.
