Abstract: The present disclosure relates to a fiber network operation apparatus for providing a method of determining a physical path in consideration of network performance and resource efficiency in a space division multiplexing-based fiber network and allocating optical resources according thereto, and an operation method thereof.

Abstract: A history of transmission/reception via a line is stored in association with the line, and it is detected whether or not a communication apparatus is physically connected to the line. Then if the line is detected to be disconnected, it is determined whether or not a history of transmission/reception regarding the disconnected line is stored. If it is determined that the history of transmission/reception regarding the disconnected line is stored, notification is given to a user that the line is disconnected.

Abstract: Described are computer-based methods and apparatuses, including computer program products, for sharing control of a voice over internet protocol (VoIP) call. In some examples, the method includes establishing a direct connection between a VoIP endpoint device and a computing device associated with the VoIP endpoint device. The method further includes communicating, via the direct connection, VoIP control signaling between the VoIP endpoint device and the computing device. The method further includes modifying a VoIP call based on the VoIP control signaling.

Abstract: A controller ensures that ring-tones of a relatively-small pool of distinct ring-tones are individually assigned to telephones of a group of telephones in such a way as to maximize the physical separation of telephones with the same or similar ring-tones. One telephone after another generates an audio signal, such as a chirp or a ring-tone, while the other telephones listen for the audio signal and report results of their listening to the controller. The controller uses the results to assign ring-tones to the telephones. A graph-coloring algorithm may be used to make the assignments.

Abstract: An IP telephone system includes a source IP telephone apparatus, a destination telephone apparatus, a Web server and an ENUM server. The IP telephone apparatuses function as base stations for multi-handset telephone systems and are connected to an IP network. The Web server stores ring tone information corresponding to a telephone number assigned to the source or destination IP telephone apparatus. The ENUM server stores a NAPTR resource record in which a URI specifies link data related to the ring tone information stored in the Web server. In the IP telephone system, the IP telephone apparatus that has received a call transmits, to the ENUM server, a query for a NAPTR record corresponding to an intended recipient's telephone number.

Abstract: An incoming call notification is performed based on a caller number extracted from a call-in signal and a user status stored in a user status storage unit, and thereby, the incoming call is notified adequately in accordance with the user status and a caller. For example, the contents of the incoming call notification is changed in accordance with a busyness of a user or an importance of the caller, and thereby, a flexible response by the user becomes possible.

Abstract: A telephone call information delivery system includes answering circuitry to answer a telephone call incoming from a service provider and to attain information input by a caller. The system further includes an information signal provider to provide at least one signal to deliver at least some of the attained information to a user. As an example, from the delivered information the user can decide whether or not to answer the incoming call. In another embodiment, the system further includes an alert signal provider to provide a signal to alert the user and an activator to receive instruction from the user. The information signal provider operates responsive to the activator. This embodiment answers an incoming call, attains information from the caller, alerts the user, the user then instructs the activator and the signal provider responds and delivers attained information to the user. The user then decides whether to answer the call.

Abstract: Apparatus and method for simultaneously providing multiple telephone-type services to any/all POTS-type devices on a single wire pair at a user premises. The present invention provides for the ability to add separately addressable POTS devices on a single service loop. This can be accomplished in at least two ways: first by the use of a multipoint protocol or second by Frequency Division Multiplexing.

Abstract: Telephone network service logic relating to calls over the telephone network to a customer terminal, uses both terminal functions and network functions. The terminal has a service logic script for execution at the terminal to control the terminal functions. To control the execution of this script remotely from the network, a script-control message is determined and sent over the telephone network to the terminal. This may use the GR30 message format, with an additional call qualifier specific to the terminal service logic script, and the type of control being requested, e.g., start execution or terminate the script. This enables the reliability of the interaction between the service logic at the network side, and the service logic script at the terminal to be improved. This enables announcement type services to be provided in which a loudspeaker on the terminal can be remotely controlled to make verbal announcements without requiring customer action to lift a receiver.

Abstract: A method and a communication device detect a service signal and include a converter having a first input which is connected to a communication channel for communicating with a network. An input device is connected to a second input of the converter for providing input signals to the converter. An echo canceller receives the input signals to form a replica of echo present in output signals from the converter for cancelling the echo and forming modified output signals. An output device is connected to an output of the echo canceller for receiving the modified output signals, and a service signal detector is connected to the output of the echo canceller.

Abstract: A call progress monitor circuit is disclosed for a digital DAA in which digital information is transmitted across an isolation barrier from phone line side circuitry to powered side circuitry. In particular, the call progress monitor circuit of the present invention converts oversampled digital transmit and receive data into analog transmit and receive signals and then combines them to produce a call progress signal that is provided to be fed to a speaker driver circuit. In addition, the call progress signal in one embodiment is filtered with a low pass filter. The call progress monitor circuit in one embodiment includes oversampled digital-to-analog converters, a summing circuit, and a low pass filter. Corresponding methods for monitoring the progress of a call utilizing oversampled digital transmit and receive signals are also disclosed.
