<p>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 said local switching exchange and by means of an access node located in said 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 said telephone terminal and by means of a network termination located in said access system, a second message preferably modulated which is a replication of said first message. <IMAGE></p> |
