E3 Failover (E3 Protection) Switch - Upto 2xE3 Links

Product Overview

AceCom's E3 Fail Over (E3 Protection) Switch allows the user to connect a single E3 line from the telephone company to an "active", as well as to a "standby" E3 terminal, such as data server / router etc., at the customer premises.

How it works?

In the event of the failure of the data server / router connected to the "A / active" port of the E3 Protection (Fail-Over) Switch, it shall automatically switch and connect the E3 line from the telephone company to the data server / router on the "B / standby" port. This ensures minimum downtime - which would have otherwise   occurred due to equipment failure connected to the "A / active" port. This equipment may be used to enhance the reliability and the efficiency of the customer's data network.

Application Note

The E3 Fail-Over Switch should be used when the customer is using a single E3 line and install "active" E3 equipment and "standby" E3 equipment (such as a ROUTER) at the customers premises. The E3 Failover Switch shall automatically switch the E3 line from the telephone company between the ACTIVE E3 data server / router and the STANDBY E3 data server / router. Should the ACTIVE E3 data server / router fail or be removed from service, the E3 line from the telephone company automatically switches to the STANDBY E3 data server / router without requiring any customer or user intervention.
