This article applies to the Ingenico iCT 220 and iCT 250 terminals.
To set up backup communication, complete the following:
1. Connect an Ethernet cable into the terminal or base.
2. Connect the same Ethernet cable into a modem, router, or switch.
3. Connect a phone line to the terminal or base.
4. Connect the same phone line to a RJ-11 jack, usually located in a wall.
Ingenico terminals will automatically switch to another connection if one stops communicating properly, if their communication priority is set to 210 (the default option for most terminals). For information on how to edit these options, refer to How to configure the communication priority order.
