Dual SIM, Four Line, Wireless Communication Gateway

is equipped with Dual Wireless Mobile Network Cards and requires SIM cards from two separate network service carriers. This configuration ensures uninterrupted connectivity by allowing the secondary SIM card to operate in the event of a network failure.

Users have the ability to set their preferred network carrier, and in the event of a detected network failure, the system will automatically switch to the secondary SIM card to maintain a connection to the help line.

The PTE-4G card connects the system to the 4G Network and utilizes two SIM cards to provide backup between network carriers such as Telstra, Optus, and Vodafone.

The PTE-FXS (Foreign eXchange Subscriber)interface card delivers an analogue line to the auto-dialing telephone, providing a dial tone, battery current, and ring voltage through the “plug on the wall
