Abstract: In a telephone network, an intelligent peripheral (IP) provides a variety of auxiliary call processing functions, such as announcement playback and digit collection. In response to each call, the IP queries a service control point (SCP) over a data network, for instructions as to processing of the call. The IP runs software to select one SCP for control of each call, from a number of SCPs on the data network, and obtain the requisite instructions for the call from the identified SCP. For each call, the IP software identifies the telephone number of the subscriber and uses the NPA-NXX and D digits from that number to access a first mapping table and obtain a CLLI code identifying an SCP. Using the CLLI code from the first table, the IP software accesses a second mapping table to obtain the CLLI code for the mate to the identified SCP. Using the two CLLI codes, the IP also goes through the second table to obtain all of the Internet Protocol addresses for the two SCPs.

Abstract: A system and method for providing IP transport and Internet services using a public switched telephone network and providing equal access. The system provides a wide area communications network serving a plurality of defined geographic areas (LATAs) served by a switched telephone network having a plurality of central office switching systems in the telephone network in each geographic area connected to a plurality of terminals in premises served by said switching systems in those geographic areas. A switched multimegabit data service (SMDS) network spans the geographic areas and a frame relay network spans the geographic areas. A plurality of Internet service providers (ISPs) are connected to the SMDS network. At least one data hub node is provided in each geographic area and each hub node is connected to the SMDS network and to the frame relay network.

Abstract: The quality of service existing in a data packet network during the course of communication of a voice call through a data network, such as the Internet, is monitored. A minimum acceptable level of service may be predefined with a threshold quality level stored in the user's Call Processing Record (CPR) in the AIN Integrated Services Control Point (ISCP). If the monitored quality is maintained in excess of the stored threshold, communication of the call continues through the established course of transmission. If the measured quality of service on the data network is not satisfactory, the routing of the call is changed to communication solely through a voice telephone network connection, which may include an Interexchange Carrier link, without terminating the call. The packet data network is thereby bypassed to obtain voice grade quality while maintaining the call.

Abstract: A system and method for providing telephone type services over the internetwork commonly known as the Internet. Wireless digital telephones in communication with wireless digital communications systems have speech coders that generate digital voice samples, and encoders that encode the digital voice samples to minimize bit errors during RF transmission. The wireless digital communications system demodulates the received modulated wireless signal transmitted by the digital telephone to recover the encoded, digital voice samples. The error correction codes within the encoded, digital voice samples are removed to recover the original digital voice samples generated by the vocoder in the digital telephone.

Abstract: A public switched telephone network utilizing program controlled switching systems controlled by common channel interoffice signaling (CCIS) and preferably an advanced intelligent network (AIN) CCIS network is arranged in an architecture to provide a methodology for facilitating telephone use of the Internet by customers on an impromptu basis. The system permits a caller to set-up and carry out a telephone call over the Internet from telephone station to telephone station without access to computer equipment and without the necessity of maintaining a subscription to any Internet service. Billing may be accomplished on a per call basis. It is a particular feature of the invention that directory assistance is offered to callers, with or without call completion at the option of the caller. Such assistance is rendered through the use of procedures presently familiar to the caller from usage of the public switched telephone network.

Abstract: A localized wireless gateway system provides wireless telephone communication, and for at least interexchange communication, provides voice telephone access to a public packet data network, such as the Internet. The wireless gateway system includes base station transceivers and a packet service gateway coupling the transceivers to the public packet data network. The packet service gateway compresses and decompresses voice frequency communication signals, and it sends and receives the compressed signals in packet form via the network. The packet service gateway also provides for signaling through the network to establish two-way voice communication sessions. In the preferred implementation, the localized wireless gateway system includes at least one radio port control unit coupled to the base station transceivers for controlling calls through the transceivers.

Abstract: A communications network comprising nodes interconnected by communication lines employs a method of allocating data rates to fragments of line bandwidth which facilitates efficient allocation of available line bandwidth. Each node maintains, for each communication line connected to it, a bit map means having a bit position associated with each fragment available in the line for keeping track of which fragments are available and which are in use. Identification of available bandwidth fragments in the line is then accomplished by finding appropriate bit values in the bit map means; fragments allocated are marked in the bit map means. A node thus need not allocate fragments contiguously, and available bandwidth is equally allocable by either of the two nodes interconnected by a particular line.

Abstract: An integrated digital network (IDN) includes a matrix and user signal ports for exchanging voice, data, IDN control, and building control digital signals between the matrix and user equipment, the digital signals comprising single samples of each signal type from each user port in each IDN sample time interval, the IDN further including a transmission system for concentrating user port digital signal samples of each sample time interval, by common signal type, into multiple bit channel signals for exchange between the user ports and matrix signal ports of the matrix switch, the matrix switch interconnecting each channel signal from one or more user ports to one or more other user ports.

Abstract: A digital computer uses a memory which is structured into objects, which are blocks of storage of arbitrary length, in which data items are accessed by descriptors which for a desired data item specify the object, the offset into that object, and the length of the data object. The computer system of the present invention further provides the ability to execute any of a plurality of dialects of internal instructions, the repertoire of such dialects being virtually infinite, since there is the ability to load a supporting microcode during operation as needed.
