Abstract: A telephone services functionality is disposed in a telecommunications network to ensure that a telephone call is processed in accordance with the telephone services respectively subscribed to by the calling and called parties. In addition, the functionality retains control over the call so that it may respond to service requests entered by either the calling or called party at any point following establishment of the call connection.

Abstract: To facilitate the processing of an incoming telephone call associated with a respective telecommunications network service an initial address message identifying the incoming call is intercepted before the message is presented to an associated toll switch that will process the call. The intercepted message is then examined in order to identify the toll switch service logic that will process the call. The resulting identity is then appended to the message and that result is then passed to the toll switch so that the identified service logic may be invoked to process the call in accord with the requested service.

Abstract: This invention relates to apparatus and a method for controlling a Digital Access and Crossconnect System (DACS) from a connected toll switching system. All control messages from operations support systems (OSS) for making crossconnect changes in the DACS are first routed to the toll switch. The toll switch extracts information needed to update its database and sends a control message to the DACS. In addition, the toll switch responds to changes in traffic patterns, perhaps due to the loss of a transmission facility, to generate a crossconnect change message to the DACS to rearrange facilities for more optimum performance. Advantageously, the OSSs for DACS control and switch control is combined and the toll network is made more responsive to traffic pattern changes and to losses of transmission facilities.
