8. Functional description The GD-01 US is used for for wireless data transmissions over the public GSM network. It can be used to link PLC:s, data loggers, security and surveillance systems or for data acquisition. The GSM services supported by the Westermo GD-01 US are Circuit Switched Data, Fax, SMS and GPRS. A data communication link can be established to another GSM modem, to an analogue modem or to a digital ISDN adapter.The protocol used when connecting to an analogue modem is V.21,V.22,V.22bis,V.
9. GSM network operators, subscriptions and services The GD-01 US support several services in the GSM network. In order to get the unit to work properly its important that the GSM service used in a specific application also is enabled on the subscription (the SIM card). When ordering a SIM card from a network operator its necessary to confirm that the specific service needed for the application is enabled before trying to set up the communication link.
