A telecommunication system for a register recall, said system comprising a local exchange (LE), an access node (AN) connected to the local exchange via a V5 interface, a wireless link system connected to the access node, and terminal equipment (MS) connected via the wireless link system to the access node. According to the invention, the system comprises elements (MS, AN) by means of which a request to set a current call into hold state is sent from the terminal equipment to the access node, a response message rejecting the request to set the current call into hold state is sent from the access node to the terminal equipment and a register recall request is sent from the access node to the local exchange.

Subscriber network element

The present invention relates to a method for establishing a telecommunication connection from a subscriber station (1, 9) of a radio system forming a wireless subscriber connection to a public switched telephone network (PSTN), in which method a call request is received from the subscriber station. For achieving a faster and simpler connection establishment than heretofore, a traffic channel is reserved from a data transfer channel (12) leading to the PSTN exchange (7) to be used by the subscriber station (1) that has sent a call request, a connection is established to the PSTN exchange (7), an acknowledgement message is sent to the subscriber station (1), and a speech path is connected between the PSTN exchange (7) and the user interface (2) of the subscriber station, whereby the sound signals fed by the PSTN exchange (7) are transmitted directly on the speech path to the user interface (2) of the subscriber station (1), and the diallings supplied from the user interface (2) of the subscriber station are transmitted to the PSTN exchange (7).
