摘要:
This invention relates to arrangements for providing a new spontaneous voice message service to any telephone customer at any telephone station when that customer encounters any destination that is busy or that does not answer. When a customer having a dual tone multifrequency (DTMF) station calls any destination that is busy or does not answer, the customer is invited, via an announcement identifying the new service, to record the caller's voice message. The announcement accompanies the returned busy tone or audible ring signal. The customer keys *867(=*VMS) and is then connected to a Voice Message Operations Center (VMOC) which prompts the customer to record the message. Advantageously, customers need not redial a VMOC number, their own number, and a destination number to reach a VMOC for storing the video message; the added convenience of this arrangement should stimulate substantial additional use of voice message service. The announcement, at very low cost, makes the customers aware of the service at the time they are most likely to use the service.
摘要:
A method and apparatus for setting up a digital broadcast call from a transmitting station to a group of receiving stations over a public switched network. A time slot interchange unit (TSIU) is used to replicate a signal, received from a transmitting station at an input port of the TSIU, to a group of output ports of the TSIU for transmission to a group of receiving stations. A data base, shared by a group of switching systems of the public switched network, includes data, activated during a preselected period of time, to translate each of two preselected numbers to one of two corresponding internal routing numbers of the switched network for accessing the input port and output ports of the TSIU, respectively. When the transmitting station dials the first preselected number and each of the receiving stations dials the second preselected number, the data base translates these numbers into the corresponding internal routing numbers for setting up a connection from the transmitting and receiving stations to the incoming port and the outgoing ports, respectively, of the TSIU. Advantageously, the broadcast circuit is made available to the broadcast conferees for a period of time limited by the active time of the translations in the data base.

A network monitor and associated control system is provided to monitor a toll network for customer signaling. A multi-tone signal processor and associated control is provided such that when signaling is detected, such signaling is validated against a provisioned list. A valid signal is reported to a central control of the network switch, which takes action in response to the signal.
