GuaranLink

A number of factors can attribute to connection failures for cellular communications, for example, loss of

cellular signal, interferences, or termination by the operator for unknown reasons. Different from the basic

heartbeat function, Moxa’s proprietary GuaranLink feature enables reliable connectivity with 4-tier intelligent

connection checks without sending excessive and costly cellular packets.

GuaranLink Recovery Process

With the GuaranLink feature, the WDR-3124A automatically tries to re-establish a connection when a

connection failure has occurred.

The WDR-3124A performs one of the following actions, depending on the number of enabled SIM cards:

• One SIM card – Resets the cellular module without rebooting the device to force negotiation between the

WDR-3124A and the base station.

• Dual SIM cards – Reset the cellular module without rebooting the device and establish a cellular connection

using the second SIM card account.
