Abstract: Public communication networks increasingly need to provide customers with a range of communication services, from baseband voice service, to computer data communications, to high speed digital data communications for multimedia and the like. Many such services would be blocked by existing telephone network line cards, which provide coding and decoding (CODEC) between analog and digital signals and process digital signals only at a relatively low, fixed bit rate. In accord with the invention, intelligent signal detection and control added to a line card selectively bypasses the CODEC and the associated connection to a time slot limited telephone exchange. The selective bypass connection provides a connection to an alternative network functionality capable of providing higher bandwidth digital services. In the preferred embodiment, the bypass provides a connection through an adaptive digital signal processor with a programmed controller.

Abstract: A communications network, for example forming a local exchange carrier telephone network, utilizes three layers of fiber optic rings. The point of demarcation between customer premises media and network media comprises an intelligent soft network interface device or “soft NID”. First layer rings carry telephone and data communications between the soft NIDs and remote terminals. Several remote terminals in an area communicate via one of the next higher level rings to a host digital terminal. The host digital terminals communicate with each other via a backbone optical fiber ring, and a media gateway controller on this ring provides high level service logic. The remote terminals and preferably the host digital terminals are service switching points (SSPs), for intelligent services provided by the network. Local legacy switches connect to remote terminals, whereas a router on the backbone provides communications to other networks, including legacy long distance networks.

Abstract: For communications interface across the line of demarcation between the customer premises media and a link of a public digital broadband communication network, a network interface device is “soft” in that it is adaptable to different service applications and readily programmable from both the network-side and the customer-side. A network-side interface provides a communications connection to a broadband network link at an edge of the digital broadband network. A customer-side interface provides communications connection to one or more media in the customer premises, for example, to telephone and LAN wiring within the premises. The soft network interface device also includes a data processing system, for controlling at least some of the communications through the interfaces. The data processing system is capable of being programmed with network service provisioning data from the public network as well as with user programming received from the customer premises.

Abstract: In various forms of telephone network signaling, automatic number identification information (ANI) includes a field of two or more ‘information’ (II) digits, typically used to indicate a calling line attribute, such as hospital line, residential line, payphone, etc. A number of situations have arisen where it is desirable to use these digits to control network functions and it is necessary to accurately pass the digits through with all call related signaling. For example, accurate II digits can enable appropriate processing, billing and payments for toll-free calls from payphones. Existing switch software, however, does not always provide the correct II digits or pass the digits through unchanged. In accord with the invention, a call requiring flexible ANI functionality triggers access to a central database, preferably in a service control point (SCP) or a signaling transfer point (STP).
