Abstract: A speech recognition engine is provided. The speech recognition engine combines multiple, different statistical language models to allow a single instance of a speech recognition engine to recognize words applicable to a first group of users and a second group of users where the second group of users is a subset of the first group of users. At least one of the multiple, different statistical language models comprises words specific to the second group of users.

Abstract: The invention includes a communication network for rotating media channels between resources of an emergency services network and a conforming emergency system (CES). A conforming emergency system and one of the resources of the emergency services network dynamically establish a first media channel between one another over a transport network. With the first media channel established, the conforming emergency system and the resource exchange messages over the first media channel to facilitate the CES in handling emergency events. Responsive to a triggering event, the CES and one of the resources (the same or another resource) dynamically establish a second media channel between one another over the transport network. With the second media channel established, the conforming emergency system and the resource exchange messages over the second media channel to facilitate the CES in handling emergency events. The first media channel may be torn down.

Abstract: The invention includes a communication network for dynamically establishing media channels between conforming emergency systems (CES) and resources of an emergency services network. The CES transmits a request message for a media channel to the packet network. One of the resources of the emergency services network receives the request message. The resource responds to the request message to dynamically establish the media channel. The CES may then exchange messages with the resource over the media channel to facilitate the CES in handling emergency events. In other embodiments, a resource transmits a request message for a media channel to the packet network. The CES receives the request message, and responds to the request message to dynamically establish the media channel. The CES and the resource may then exchange messages over the media channel to facilitate the CES in handling emergency events.

Abstract: An architecture for providing interactive broadband products and services uses existing cable and telephone plant. The architecture includes a central office switch in communication with a head-end server and a Customer Premises Equipment (CPE) device such as, for example, a modem emulator, data terminal, set-top terminal or personal computer. The CPE device is provided in communication with the head-end server via cable plant for downstream broadcasts and is further provided in communication with a central office switch via telephone plant for upstream signaling and downstream control messages.
