6 LTE filter table Attention: In order to avoid a data jam in the area/line couplers*, we highly recommend not to use more than 15 devices in the same zone if the zone reaches over the line coupler. Example: a lot of controllers switch from ECO to COMF and all controllers send the confirmation message back at the same time. This is valid for the following zones: * The same rule is valid for IP routers as well!
