Abstract: A system for providing lifeline telecommunication service includes a gateway, an analog signal service module, and an integrated access device. The gateway receives telecommunication information from a telecommunication switch and generates data packets for communicating the telecommunication information. The analog signal service module is remotely coupled to the gateway. The analog signal service module may receive the data packets from the gateway and generate a first analog telephone signal for communicating the telecommunication information over a local loop circuit. Coupled to the local loop circuit, the integrated access device may receive the first analog telephone signal from the analog signal service module and communicate the first analog telephone signal to a subscriber line in a first mode of operation.

Abstract: A method reliably communicates content for multiple subscriber lines via a single physical transmission medium between a telecommunication gateway and equipment at a customer location. In that method, content for two or more subscriber lines of the customer location is received and converted into packetized data for network communications and/or multiplexed to form an added-main-line (AML) signal that includes power. The packetized data or the AML signal is communicated between the customer location and the telecommunication gateway via the single physical transmission medium. External power can be used to extract the content for the two or more subscriber lines from the packetized data in a primary mode of operation, and the power from the AML signal can be used to extract the content for the two or more subscriber lines from the AML signal in a backup mode of operation.

Abstract: A voice gateway (18) in a telecommunications network (1) includes a plurality of telephony port modules (102). Each telephony port module (102) receives telephony voice signals from a public switched telephony network (13). Each telephony port module (102) includes one or more digital signal processors (110) that perform one or more processing functions on the telephony voice signals. A particular telephony port module (102) may receive a telephony voice signal and use its associated digital signal processor (110) to process the received telephony voice signal or transfer the received telephony voice signal for processing to any digital signal processor (110) on any telephony port module (102). Telephony signals may also be transferred for processing to digital signal processors (110) on another voice gateway (18) in a voice gateway system.

Abstract: A backplane (11) of a telecommunications chassis includes a pair of controller slots that can receive respective controller modules. The backplane (11) also has a plurality of module slots that can receive respective telephony modules. Each of the pair of controller slots is connected by a plurality of buses to each of the plurality of module slots. The backplane (11) provides the ability to place any module type into any of the plurality of module slots.

Abstract: An apparatus for communicating telecommunication information between customer premises equipment and network equipment includes a subscriber line interface, a processing module, and a bypass switch. The interface receives an analog telephone signal communicating telecommunication information from a subscriber line. The processing module receives the analog telephone signal and processes the analog telephone signal to generate data packets for communicating the telecommunication information over a local loop circuit in a first mode of operation. The bypass switch communicates the analog telephone signal from the interface to the processing module in the first mode of operation and communicates the analog telephone signal from the interface over the local loop circuit to the network equipment in a second mode of operation.

The gateway receives telecommunication information from the telecommunication switch. The gateway generates data packets for communicating the telecommunication information over a local loop circuit in a first mode of operation or generates a first analog signal for communicating the telecommunication information over the local loop circuit in a second mode of operation. The processing module receives the data packets from the local loop circuit and processes the data packets to generate a second analog telephone signal communicating the telecommunication information in the first mode of operation.

Abstract: A system for communicating telecommunication information between a telecommunication switch and multiple local loop circuits includes a telecommunication interface, a data packet service module, an analog service module, and a cross connect. The telecommunication interface receives telecommunication information from a telecommunication switch. The data packet service module receives the telecommunication information from the telecommunication interface and generates data packets for communicating the telecommunication information in a first mode of operation. The analog signal service module receives the telecommunication information from the telecommunication interface and generates an analog telephone signal for communicating the telecommunication information in a second mode of operation. The cross connect communicates the analog telephone signal to a selected one of the local loop circuits.
