Connecting a NetCam1 sending unit to the analog telephone network:
Connecting a NetCam1 sending unit to the GSM-network:
Simultaneous ISDN and modem/GSM connection for fault tolerance:
In addition to a plain transmission over analog and wireless networks these capabili-
ties of the NetCam system can be used in combination with ISDN towards fault toler-
ance. If connection over ISDN fails or an ISDN alarm occurs, signalling loss of ISDN
availability, a backup connection over analog lines or wireless networks can be estab-
lished to transmit the alarm and/or loss of ISDN connectivity. Conversely, loss of GSM
or modem connection can be signalled over ISDN.
