An apparatus and a method are provided for processing audio and/or video data comprising a module for displaying an element comprising at least one absolute time or at least one time indicator, wherein a sector or portion associated with the element indicates a duration or a length of the audio and/or video data, wherein time marks are displayed that are set automatically or by user interaction.

Apparatus and method for processing audio and/or video data

The invention relates to a method for controlling recorded announcements and interactive voice responses for calls made outside an exchange, using a packet network (PN), by means of peripheral equipment (LTG) of a switching system, which does not provide any HW-oriented tasks for its interface system controlled by switching technology, whereby peripheral equipment (LTG) with virtual ports is defined. The method is characterised in that resources for the recorded announcement and interactive voice response function are provided by an external device, that the peripheral equipment is provided with virtual recorded announcement and interactive voice response ports, that an interface exists between the peripheral equipment and the external device and that the external resources can be used in relation to a specific port by the switching system.

Method for controlling recorded announcement and interactive voice responses in packet networks

The invention relates to a method for transmitting data having a reduced bandwidth wherein the amount of data intended for transfer over a data transfer network is reduced by a reduction method, wherein the type of reduction performed is signaled by a source switching device to a terminal switching device in the data transfer network, such that in the terminal switching device, transferred data is processed using a partner method to the reduction method in order to recover the original data.

Method, switching devices and remote connection unit for transmitting data having a reduced bandwidth

Commercially available platforms with performance characteristics are linked with network systems via standardized interfaces. Such a link, however, requires major interventions in the structure of said system. The inventive method reduces the necessary steps by means of a message-based concentration on the network bandwidth or a multiple thereof and a line-based concentration on the bandwidth of one of the peripherals during communication, thereby scheduling at least one interface of the allocated control device.

A telecommunications system having a packet-switching communications network, and to a method for operating such a telecommunications system, wherein at least a first subscriber is connected to a packet-switching communications network, a network element of a circuit-switching communications network is connected to the packet-switching communications network using an interface unit, and a first signaling information is transmitted between the network element and the subscriber, the first signaling information corresponding to a signaling standard of a circuit-switching communications network.

Telecommunications system having a packet-switching communications network and method for operating such a telecommunications system

A method and a network element for processing signaling data and for controlling connections of subscribers of a packet-switching communications network. A network element actuates a concentrator interface using at least one connecting unit and makes resources available to it. Signaling data for performing subscriber signaling of a subscriber of the packet-switching communications network is transmitted between at least one packet control unit and the connecting unit via a message control system of the network element. The packet control unit converts the signaling data of the network element into signaling packets of the packet-switching communications network and vice versa. The signaling packets are transmitted between the network element and the subscriber.

The invention discloses data records which are stored in one of a plurality of service devices, and an address list which keeps the other service devices which likewise keep the data record, with a change which is initiated by the customer being carried out on one of the service devices which keep that data record, and this service device reports the change to the other service devices.

Method for updating subscriber-related data in a telecommunication network

A method for permitting transparent handling of signal messages and voice information of a subscriber to a desired network operator through at least one local exchange of a network operator physically allocated to the subscriber.

Method for linking subscribers to plural communication networks

In the prior art, the storing of subscriber-related data ensues in the peripheral installations of the communication system. This requires a great deal of memory space. In order to minimize this, the subscriber-related data is stored, per interface to a subscriber connection network, in only one of the peripheral installations, or, if redundancy is required, in two of them.

Method for storing subscriber-related data in communication systems

In a method for loading software in communication systems with non-redundant, decentralized equipment so that the availability of a communication system for the connected subscribers remains assured during the loading process of programs and data, there is a requirement to maintain switching operations during the loading process. Given the presence of V5.2 interfaces, the loading occurs such that the V5.2 communication channels are first rerouted onto the redundant system half. During this time, the new software can then be loaded into the other system half. When the loading into this system half is concluded, then it is placed in operation and all V5.2 communication channels are routed onto this system half. The new software can then be loaded into the remaining system half.

A packeting time of 6 ms is required for filling the information part of an ATM cell with 48 octets of a 64 kbit/s channel. This transit time is impermissably long for PCM voice connections. This situation is alleviated in that the information part of the ATM cells is subdivided into 24 fields of two octets each. Two respective data octets of a channel are then entered therein.

Method for transmitting digital signals in an ATM communication network

Contemporary communication systems must have extremely high availability and malfunctioning equipment must be repaired and replaced as quickly as possible. To this end, optical displays are provided for all equipment. An optical display is driven in case of malfunction as a function of the results provided by a fault procedure, whereby the drive of the optical display displays current information indicating the permissibility and necessity of equipment replacement. The advantages of this procedure are fast repair of the fault and enhanced availability of the communication system.

Method for system-prompted fault clearance of equipment in communcation

A communication system is prepared to be placed into service, or an in-service system is updated or re-started, by transmitting programs and data into the peripheral equipment of the communication system. So that the availability of the communication system for the connected subscribers remains assured, there is a need for accelerated loading. The loading ensues by segmenting the programs and data on the storage medium at the central station as well as by the transmission of the segments into the designated peripheral units. A synchronous connection is provided between two redundant peripheral units forming a pair and is utilized in the loading event to transfer data or programs as needed between the units of the pair.

Method for preparing de-centralized redundant units in a communications

Bit falsifications occur in the switching networks of digital communication systems in the transmission through these switching networks of bit streams composed of a plurality of information words. By correcting these bit errors, only a correctly transmitted information word is forwarded to a destination subscriber after the transmission given redundantly executed and activated switching network halves. Whether an information word was correctly transmission is determined after the transmission with a combined parity bit check as well as bit-by-bit comparison to the information word transmission in parallel. It is assured that bit falsifications of the units (holding memories) participating in the transmission process are detected and corrected.

Method for on-line monitoring and bit error reduction for

A method for reducing bit error in a digital communications system including the step of identifying whether a data or information word was correctly switched through a network having at least three switching levels after the data word has been switched by undertaking a parity bit check as well as a bit by bit comparison of the bits in the data word, and an apparatus configured to perform the method. Bit errors are corrected either on the basis of majority decision or by a Statistical evaluation of the bit error rates of the various switching levels of the switching network.
