Abstract: A method, system and apparatus for reducing dataflow disruption when increases in path maximum transmission unit (PMTU) are being detected are provided. Conventionally, when increases in PMTU are being detected, an increased-in-size data packet is sent by a transmitting host. If an intermediate link is unable to process the data packet through, it drops the data packet and sends an error message to the transmitting host. The transmitting host has to reduce the size of the data packet and resend it. The procedure outlines in this disclosure obviates the need to resend the data packet. It does so by transmitting an old data packet that has been increased in size. Hence, there is no need to resend the data packet if it is dropped.

Abstract: A method for creating a telephone digital switching platform to provide conversion and routing of telephone calls arriving on a number of telephony interfaces to a number of outbound telephony interfaces, based on in parameter and out of parameter call setup information. Receiving and transmitting interfaces can include, but are not limited to, Integrated Services Digital Network (“ISDN”), Digital Transmission Carrier System (“T-1”), DID (“Direct Inward Dial”), Loop Start, (“E & M”) and Direct Outward Dial (“DOD”). Conversion and routing is performed by the steps of capture of call setup information, conversion to “dial number” via database lookup, selection of outbound pathway based on database information, and placement of outbound call and switched connection to inbound call.

Abstract: A method of communicating speech across a communication link using very low digital data bandwidth is disclosed, having the steps of: translating speech into text at a source terminal; communicating the text across the communication link to a destination terminal; and translating the text into reproduced speech at the destination terminal. In a preferred embodiment, a speech profile corresponding to the speaker is used to reproduce the speech at the destination terminal so that the reproduced speech more closely approximates the original speech of the speaker. A default voice profile is used to recreate speech when a user profile is unavailable. User specific profiles can be created during training prior to communication or can be created during communication from actual speech. The user profiles can be updated to improve accuracy of recognition and to enhance reproduction of speech. The updated user profiles are transmitted to the destination terminals as needed.

Abstract: A method of detecting and recovering from an out-of-band signaling failure in a telecommunications network involves the reprogramming of switching centers to utilize existent inband signaling capabilities to temporarily replace the failed out-of-band capability. A processor of an originating switching center recognizes the loss of out-of-band signaling capability, determines impacted trunks and switches to in-band signaling from out-of-band signaling. In an alternative embodiment, the switch may use maintenance data bits of impacted trunks to initiate a call. The terminating switching center is programmed to receive and recognize the change in bit value of the signaling data and initiates well known processes to seize the trunk in memory, check continuity and receive dialed number data, preferably in the form of tones, over the seized trunk. The terminal switching center for the trunk then attempts to complete the call in accordance with the received dialed number data.

Abstract: A voicemail message processing system. A voicemail message is sent to a remote recipient on a remote voicemail system. In response, the remote voicemail system sends an acknowledgment message containing information on the remote voicemail user. This information is stored for later use in addressing messages to the remote user, such as providing voice confirmations and address by name capabilities.

Abstract: Access (or egress) charges payable by an IXC to a LEC, and payable by the subscriber to the LEC for originating or terminating calls and for associated vertical call control features, are reduced or eliminated by providing a virtual piped collection that "bypasses" and thus does not require the involvement of, a local service provider. The virtual piped connection exists between a call control platform (CCP) in the IXC network, and specialized customer premises equipment (CPE) located m the subscriber location. The specialized CPE is arranged to provide call control functions using normal out-of-band signaling in a conventional manner, and, after an initial call is conventionally set up to the CCP, to provide the same functions using specialized in-band signaling. A complementary signaling and control capability is provided in the CCP.

Abstract: A telephone system wherein any one of a large number of telephones is connectible to a local directory-assistance request processor. The name of a subscriber whose telephone number is sought is entered through a connected telephone by spelling out the subscriber's name with the standard telephone push-buttons, using the grouped alphabetic designators on those buttons. The resulting decimal signals are stored in the request processor, and also are forwarded by a digital transmission system to the appropriate one of a number of directory processors each having a subscriber data base in alphanumeric code. A look-up is carried out to locate the alphanumeric code data identifying the subscriber's name corresponding to the originally-entered decimal request signals, and the located alphanumeric information including name and telephone number is sent back through the digital transmission system to the request processor.

Abstract: Instead of setting the type of a dial signal for a central office line connected to a private branch exchange to either a DTMF signal or a pulsed signal externally of the private branch exchange, the line is acquired and a DTMF signal is transmitted from the private branch exchange to the line so that the line is recognized as a dial line for the DTMF signal when a dial tone coming from the line disappears but as a dial line for the pulsed signal when the dial tone does not disappear. Results of recognition are set in the private branch exchange and the type of the dial signal for the line is set automatically in accordance with the results.

Abstract: An interface is described which attaches between the incoming trunk lines from a central office and a PBX system and which monitors the communication between the central office and the PBX to record the signals representative of telephone extension of a called party for later downloading to telephone peripheral equipment attached to the PBX, such as voice mail systems. The interface passively monitors the line during handshake communication between the central office and the PBX and receives the digits of the dialed extension and stores them in memory. The interface then monitors the line for a request to send from the peripheral equipment attached to the PBX. When the request is received, the interface assumes supervision of the telephone line by terminating the line to the central office and the line to the PBX. The interface then downloads the digits of the dialed extension to the telephone peripheral equipment, such as a voice mail system, for identifying the extension to which the message belongs.

Abstract: A PBX system is responsive to an incoming call which is directed to an adjunct of the system for sending a ringing signal over a station facility to the adjunct. When the adjunct goes off-hook, the system outputs to the adjunct over the station facility multi-frequency tones containing information associated with the incoming call prior to establishing a connection between the adjunct and calling party. The information selects the proper operating mode of the adjunct and provides other call processing information to the adjunct. The adjunct communicates information to the PBX using a switch-hook flash and multi-frequency tones.

Abstract: A digital FSK trunk dialing converter including M and E lead control is disclosed. The dialing converter further includes an FSK detector which is responsive to consecutive half period intervals of a received FSK signal, and a digital signal-to-noise (S/N) detector or estimator which operates to inhibit or keep the E-wire signal lead deactivated in the presence of noise signals which are received from the communications link in absence of acceptable FSK signals. The FSK detector is comprised of two digital circuits which generate pulses indicative of whether the received FSK signal is greater or less than the FSK center frequency. The pulses are integrated and used to trigger a flip-flop which provides a demodulated digital FSK output indicative of a received high or low FSK analog frequency. An E-wire control signal is generated in the receive logic circuitry in response to the demodulated FSK output.

Abstract: A signalling receiver has its signal input (E) connected to a central-office trunk (a, b) in a trunk junctor and includes a variable bandpass filter (BP) connected to a clock line (TL). The signal input (E) is connected via an attenuator (DG) to a variable high-pass filter (HP) which is connected to the clock line (TL) and, via a signal evaluation and conversion unit (SE), to the bandpass filter (BP). A bandwidth switch (BU) is connected to the clock line (TL), the variable bandpass filter (BP), and the attenuator (DG). The cutoff frequency of the high-pass filter (HP) and the midband frequency of the bandpass filter (BP) are adjusted with a clock signal having a frequency related to the signal frequency to be received, the cutoff frequency being lower than the midband frequency.
