Abstract: A call fallback scheme is provided in a packet switched network. After receiving incoming calls, a Voice over IP (VoIP) link is established over a packet switched network with a destination endpoint. VoIP packets are generated from the incoming calls and sent over the VoIP link to the destination endpoint. When a low quality of service condition is detected on the VoIP link with the destination endpoint, a fallback call is established with the destination endpoint over a circuit switched network. The VoIP packets for the incoming calls are redirected from the VoIP link to the circuit switched data link. As opposed to simply hairpinning a TDM voice call back over the PSTN network 102, the same VoIP packets for the incoming calls originally destine for the destination endpoint over the packet switched network are rerouted through the fallback call. This simplifies synchronization with VoIP packets sent over the VoIP network. Because VoIP packets for more than one call can be sent over the fallback call, the cost of maintaining the fallback call is also substantially reduced.

Abstract: A data messaging method for communicating a short data message between a message sender and a message recipient using the existing facilities and capabilities of the public switched telecommunication network and without establishing a telephonic connection therebetween, thereby reducing the time and cost required to communicate a data message between the parties as compared to current methods. In a preferred embodiment, the method communicates a user-definable data message between a message sender having telephone terminal equipment and a plurality of telephone lines associated therewith, and a message recipient having telephone terminal equipment and a telephone line associated therewith. According to the method, a first plurality of data message portions are associated in one-to-one correspondence with the message sender's plurality of telephone lines. The data message is then parsed into a second plurality of data message portions taken from the first plurality of data message portions. The second plurality of data message portions are communicated to the message recipient by initiating successive telephone calls to the message recipient's telephone line on message sender telephone lines which are selected for their respective association with data message portions of the first plurality of data message portions that match the data message portions of the second plurality of data message portions. Upon receiving information identifying the message sender telephone lines from a calling party identification service, the data message portions of the first plurality of data message portions corresponding to the selected telephone lines are determined and presented to the message recipient.

Abstract: Allowing a calling party to enter a message that is transmitted on a destination telephone link during silent intervals of a ringing signal by a switching office. In a first embodiment, the destination telephone link is equipped with the feature of allowing receipt of calling party specified data messages. The switching office automatically accepts information for a data message as dialed digits from the calling party. In a second embodiment, the switching office designates that an originating telephone link can transmit information for a data message. The switching office is responsive to the transmitted information to form a data message and to transmit this data message on a destination telephone link during the silent intervals of the ringing cycles. In a third embodiment, in response to a calling party placing a call to a special telephone number, the switching office requests that the calling party enter a destination telephone number and information for a data message. In another implementation of the third embodiment, the switching office transfers the call to an adjunct system that receives the destination telephone number and information for a data message. Then, the adjunct system requests that the switching office set up a call between the calling party and an identified telephone link and transmit the data message on the identified telephone link during the silent intervals of the ringing cycles. In a fourth embodiment, the switching office is responsive to called party information and data message information in a setup message received from an ISDN telephone link to establish a call between the ISDN telephone link and a telephone link identified by the called party information. Further, the switching office is responsive to the data message information to form a data message and to transmit the data message on the identified telephone link during the silent intervals of the ringing cycles.

Abstract: The present invention maintains calls during transfers between different types of subsystems, even when there is a bearer path interruption at the user element due to the original connection from the transferring-out subsystem being dropped before the new connection in the transferring-in subsystem is established. The call signaling leg toward the remote endpoint of the remote party is held, while the call signaling leg toward the user element is moved from the transferring-out subsystem to the transferring-in subsystem and a new bearer path is established via the transferring-in subsystem. During transfers with a bearer path interruption, a portion of the bearer path leading to the remote endpoint may be connected to a media resource function, which will provide an announcement to the remote party. Once the user element is accessible in the transferring-in subsystem, the bearer path is further transferred to the user element via the transferring-in subsystem.

Abstract: A method and a Network Element (NE) for manifesting alarms by forming a so called combined Data Quality Byte (DQB) for a particular SDH/SONET data transmission stream. The DQB indicates status of alarms at a particular location of the telecommunication network, via which the stream is transmitted. The DQB can be formed by arranging a plurality of alarm signals, currently actual for the particular data transmission stream, in a predetermined byte associated with the stream frame. The NE, upon receiving from an upstream network element a data transmission stream with its DQB1 formed upstream, creates an updated DQB2 and compares DQB1 with DQB2 to manifest an alarm status change ΔDQB for estimating quality of transmission via the network section.

Abstract: In order to identify a teleservice during the setting up of a connection in a telephone network (PSTN) from a calling point (TXA) to a target subscriber (TNB), a signal recognition device (22) is temporarily applied to the requested connection on the basis of the call request (20) in a switching center of the network, preferably in a target switching center (VSB) associated with the target subscriber, said signal recognition device being sufficient at least for emitting a service call signal indicating a teleservice, via the calling point (TXA). When a service call signal is received (23) by the signal recognition device, said signal is evaluated in terms of the service indicated, and the connection (24-26) is further treated according to the service thus indicated. For the recognition of a teleservice when establishing a call in a telephone network from a calling party to a target subscriber, on the basis of the call request, in an exchange of the network, preferably a target exchange assigned to the target subscriber, a signal identifier is temporarily applied to the requested call, for a duration that is at least sufficient for the calling party to send out a service call signal that indicates a teleservice. If a service call signal was received by the signal identification, this signal is evaluated with regard to the indicated service, and further handling of the call is carried out as a function of the service indicated in this manner.

Abstract: According to this invention, a digital key telephone system connected to an analog public network NW having a function of transmitting a ringing signal including identification information of a calling line through a subscriber line (CO line), accommodating a plurality of extension lines each connected to a digital key telephone (DKT) 2 or a standard telephone (STT) 4 as an extension terminal, and having a function of switching and connecting the subscriber line to the plurality of extension lines or the extension lines to each other includes a called party storage means storing, in advance, information representing the correlation between the calling line and the extension terminals 2 and 4 as a called terminal. When a ringing signal arrives from the analog communication network NW, calling line identification information (caller ID) contained in the ringing signal is detected by a calling line identification information interface unit (RCIU) 12. A control unit (RCTU) 16 determines the called extension terminal on the basis of the detected caller ID and the information stored in the storage means, so the extension terminal receives the call from the digital key telephone interface unit (RDKU) 13 or a standard telephone interface unit (RSTU) 15.
