By using this dialog, it is possible to connect via a standard Hayes-compatible modem to an RTCU device. The connection will be made through the GSM module of the RTCU device. The dialog will stay on top of the screen as long as there is an active connection.
For establishing a modem connection, there are two distinct possibilities. These are as follows:
•RTCU device using a SIM-card with a dedicated data number (usually a paid option). In this case, the data connection can be established using a standard analogue modem. Calling the standard number will simply result in the call terminating as a voice.
•RTCU device using a standard SIM-card with only one call number shared for data and voice calls. To ensure that the call bearer information is present, a V110 ISDN or GSM CSD connection must be used to establish the connection.
Please note that country code typically is prefixed with 00 (e.g. 0045 for Denmark).
Note: Modem/CSD connections are considered obsolete and is not supported by most Mobile networks. The latest NX32L generation of devices also do not support Modem/CSD connections.
