    • Parameterization of the modem:
      Make the same settings for the landline network and the WAN interface as for the GSM network (except "AT initialization"). Parameterize the AT strings according to the modem you are using (ISDN or analog modem).
    • Telephone number:
      If the SMS is sent from the landline network, you enter the telephone number of the node without the country code!
    • SMSC telephone number:
      • The telephone number of the SMS center depends on the type of connection (analog, ISDN or GSM network). You obtain the number from your provider.
      • The special service for sending SMSs via the landline network depends on the provider. More information on the special services is available in Entry ID: 24045718.
