发明名称 Method and system for transmitting messages to subscribers during the set-up stage of incoming telephone calls
摘要 Method and system for transmitting messages to subscribers of a telephone network during the set-up stage of incoming calls prior to the off-hook from a local exchange to at least one telephone terminal through an access system. The access system simulates, on one hand, the operation of a telephone terminal towards the local switching exchange such that it receives, from the local switching exchange and by means of an access node located in the access system, a first message preferably modulated and demodulates and stores it for subsequent replication; and, on the other hand, simulates the operation of a local switching exchange towards the telephone terminal such that it generates and transmits to the telephone terminal and by means of a network termination located in the access system, a second message preferably modulated which is a replication of the first message.
