Method to perform dialing in a wireless local loop system, a wireless local loop system and a terminal

A wireless subscriber interface system comprising:

• at least one terminal (302);
• a subscriber device (301) connected to the terminal;
• at least one base station (351);
• means (301) to dial a connection code comprising at least one symbol;
• means (301) to generate a symbol signal on the basis of the dialed symbol;
• communication means (310, 313, 304, 350, 351) to transmit the dialing information from the terminal to the exchange;
• and
• means (352, 353) to establish a communication link from the terminal on the basis of the transmitted dialing information;
• characterized in that it further comprises
• sampling means (323) for sampling said symbol signal;
• a register (320) for storing the sampled symbol signal;
• means (311, 314) to read the symbol signal stored in the register;
• and
• means (322, 314, 313, 304, 350, 351) to transmit the read symbol signal as dialing information from the terminal to the exchange.

A terminal which can be connected to a WLL communication system and which comprises:

• an interface to connect a subscriber device (301) to the terminal;
• means to receive symbol signals from the subscriber device connected to the terminal;
• and
• communication means for transmitting the dialing information to an exchange of the communication system;
• characterized in that if further comprises:
• sampling means (323) for sampling the received symbol signal;
• a register (320) for storing the sampled symbol signal;
• means (311, 314) to read the symbol signal stored in the register;
• and
• means (313, 314) to transmit the read symbol signal to the exchange.
