Connection method for telecommunications network e.g. integrated services digital network, supplied stored information to calling subscriber before charge-free connection to second subscriber

摘要

The connection method establishes a connection between 2 telecommunications network subscribers (TE1,..TEn) using an exchange (SPX) having a databank (DBP) storing information transmitted to the calling subscriber (TE1) during an initial interval, with charge-free connection to a second subscriber (TE2,..TEn) during a second interval. The information stored in the databank may be selected for transmission to the calling subscriber by evaluation of the calling subscriber number.
