In Line Gateway Scenario

One of the many implementations of a Far South Unit is using it as a gateway in conjunction with an existing legacy PBX. In this scenario we make use of the versatile 2O2S card.

Scenario

A company has an existing PBX and requires a need for an in line gateway to route traffic through the 2O2S card. Port 1 (FXS) connects internally to Port 4 (FXO) and Port 2 (FXS) connects to Port 3 (FXO) via bypass circuitry providing a lifeline service during power failures. In this example below, the 2O2S card is situated in slot 2 of the Com.X10 numbered port 2-1 to 2-4.

Now that we have identified the ports we can proceed with the setup. Assuming a PSTN service is supplied by the Provider (Telco), this will be presented to the FXS ports of the Com.X (2-1 and 2-2). The FXO ports (2-3 and 2-4) will be fed to the legacy PBX.

The GUI setup is simple. The calls coming from Telco into the FXS ports need to be routed to the outbound FXO ports / trunk group. By means of a flexpath we can make that happen. In the below example, a simple flexpah (Divert) has been created, using the Include function, all calls will be routed to Outbound and its predetermined FXO port or trunk group created to push calls to the legacy PBX .

All we have to do now is allocate the flexpath to the intended FXS port.

These calls will push through to the legacy PBX via FXO and can be managed as such.

Similarly this scenario can be applied to ISDN configurations (BRI / PRI) depending on specification.
