A fiber-optic communications interface () and method of operation that operates with a paired fiber-optic communications interface () in a redundant communications termination point (). The fiber-optic communications interface () has a paired card interface () that exchanges at least a first subset of status data between a local bearer processor () and a paired bearer processor () located within a different card cage (). The local bearer processor () processes bearer data channels communicating with a remote site () through a remote site fiber-optic line (). A local data interface () exchanges data contained in the bearer data channels between the local bearer processor () and a local user data network (). The local data interface () also exchanges at least a second subset of the status data with the paired bearer processor () through the local user data network ().

System and method for sonet equipment fault management

A distributed switching system comprising a call controller, multiple source modules, and multiple destination modules provides circuit switching functionality without using a centralized circuit switch. When a source module of the multiple source modules receives inbound data, the source module broadcasts the data to each destination module of the multiple destination modules via an inbound time slot of multiple inbound time slots. The call controller selects a destination module of the multiple destination modules to process the data and informs the selected destination module of the inbound time slot. The selected destination module then receives the broadcast via the inbound time slot and processes the broadcast data. The distributed switching system further provides for a transfer of data in an outbound direction by allocating an outbound time slot in which the selected destination module embeds tagged data for receipt and forwarding by the source module.

Distributed automatically-configuring switching system

Line terminal equipment () transmits health and status information () to bearer payload processors (-N). Each bearer payload processor (-N) concatenates () the health and status information of the line terminal equipment. Each bearer payload processor transmits the concatenated health and status information including bearer traffic to each of the line terminal equipment (). Both the line terminal equipment and bearer payload processors compare () the health and status information.

Signaling method for line terminal equipment health and status

An automatic protection arrangement for a communication system () provides a working line terminal equipment (and a link (A) for transmitting bearer traffic from a number of bearer payload processors (-N) to a switching center (). The arrangement also has a protection line terminal equipment () and link (A) coupled to the switching center (). For detected faults, an instantaneous switch over occurs of the bearer traffic of the bearer payload processors (-N) from the working line terminal equipment () to the protection line terminal equipment ().

Extended automatic protection switching arrangement

The present invention provides a method for routing data from a service request in a communication system. A context is transferred from a packet data gateway, such as a Serving GPRS (GSM Packet Radio Service) Support Node (SGSN), to a Base Station System (BSS) coupled thereto. The context specifies where data for this user should be sent. The service request is received at the BSS and includes data. The data from the service request is routed to an appropriate location, based at least in part upon the context.

Method for routing data in a communication system

During a wireless communication of data in which modems (21, 24) are in use, a method of handing off the communication link (32) is described. The communication link (32) is handed off from a source base site (22) to a target base site (23). An interworking function (33) is then transfered from a source interworking unit (25) to a target interworking unit (26) by transfering protocol status (42) such as transmission control protocol. A cut over (34) from the source modem (21) to a target modem (24) is conducted once the interworking function (33) is transfered.

Conducting handoff of a data transmission

A base station system (203, 303) in a wireless communication system (208, 308) establishes a link between a mobile station (200, 300) and a speech recognition system (209, 312). When the base station system (203, 303) determines that such a connection is required, the base station system (203, 303) instructs the mobile station (200, 300) to switch from a first codec (201) specific to human speech to a second codec (202) specific to speech recognition. Only after the switch between codecs in the mobile station (200, 300) does the base station system (203, 303) establish the link between the mobile station (200, 300) and the speech recognition system (209, 312).
