2N SmartGate features outstanding functionalities which are as follows:

  • Cost Saving Effect:

    Using 2N SmartGate analogue GSM gateway you can save half of your company telephone bills since all calls directed to GSM networks are routed through 2N SmartGate and extortionate bills for the PSTN-GSM connection are avoided.

  • Mobility Extension function added!

    With the latest firmware (included in the programming tool) you may use 2N SmartGate as a Mobility Extension.

  • DialThru function:

    A great advantage of 2N SmartGate is its DialThru function. When you connect this GSM gateway to your standard telephone set, you can call directly to the PSTN and GSM network.

  • FXO and FXS ports:

    2N SmartGate is equipped with both FXS and FXO interfaces. It can be installed on a PBX trunk line (FXS port), a PBX extension line (FXO).

  • G3 Analog Fax support (optional):

    It is possible to connect an Analog Fax to 2N SmartGate and send/receive fax.
    Supported protocols:
    V.27ter (2400bps a 4800bps)
    V.29 (7200bps a 9600bps)

  • CallBack

    When the CallBack function is activated, the GSM gateway refuses to receive this incoming call. In case the calling party terminates the call before the timeout, the GSM gateway starts calling to a defined extension. When the extension picks the call up, the gateway starts calling to the GSM (called party number = CLIP of the incoming call).

  • Low Credit Info:

    From now on, you do not have to worry about information on your prepaid SIM card status. You can configure the gateway to receive a "LOW CREDIT" SMS message whenever the SIM card credit gets below a pre-programmed amount, e.g. 5EUR.

  • GPRS connection:

    The GPRS connection enables e-mail communication and Internet browsing. It is often used as a back up internet connection for small offices, or primary internet connection on boats or in distant areas.

  • SMS sending and receiving:

    2N SmartGate enables all LAN users to send and receive SMS with a 2N network
    application - the SMS server. The delivery status of any message can be obtained automatically.
