    STENTOFON Analogue Telephone Gateways make it easy to connect your AlphaCom intercom system to the public telephone network or a PABX. The gateways come in two versions with 4 or 8 analogue telephone lines, providing a modular and cost efficient way of connecting to the external telephone system. Multiple analogue gateways can be added, if even more external lines are needed.

    In case your system consists of multiple AlphaCom nodes, it is possible to share gateways between them in order to further reduce telephone fees and save hardware costs. It is easy to make outgoing calls to telephones:

    1. Dial a prefix - wait for a dial tone - dial the phone number.
    2. A complete number can also be stored under a DAK key or a substation call button for direct dialling.

    Calls from the telephone system can be handled in three ways:

    1. A second dial tone is presented to the caller, then the caller dials the number identifying the station to be reached.
    2. The call can be forwarded to a predefined station in a control room or a switchboard. From there, the call is transferred to the right person.
    3. There can be a combination of these two – the caller may dial the wanted number after a second dial tone, or be transferred to a predefined station if no further dialling is made.

    The STENTOFON Analogue Telephone Gateways supports high quality audio due to the advanced digital signal processing capabilities of the AlphaCom and the Gateways. The gateways are easy to configure via a web-interface.
