Understanding the Functions of the SRX210 Services Gateway with Integrated Convergence Services

SRX210 Services Gateway with Integrated Convergence Services functions as follows:

Analog telephones and fax machines are directly connected to the SRX210 Services Gateway with Integrated Convergence Services through Foreign Exchange Station (FXS) interfaces.

The telephone exchange or PSTN central office is directly connected to the SRX210 Services Gateway with Integrated Convergence Services through Foreign Exchange Office (FXO) interfaces.

The media gateway converts analog signals from FXS and FXO ports and digital TDM signals from T1/E1 ports to VoIP packets and sends them to the network after processing through JUNOS software secure routing and firewall flows.

Similarly, the media gateway receives forwarded VoIP packets from the network, and converts them into analog signal or digital TDM signals and send them across the appropriate interface.

The media gateway also provides power failover support in the event of power loss by providing a hardware relay between the built-in FXS2 port and FXO1 port, which automatically connects the two ports when the media gateway loses power.
