2N SmartGate has two telephone ports – FXS and FXO. There are four possibilities how to use this device:
- DialThru gateway – basic connection – Phone set is normally connected to extension line of PBX. Wire up 2N SmartGate between phone set and PBX. Link extension line of PBX to FXO interface and phone set to FXS interface on 2N SmartGate. Similarly you can connect analogue fax (special model of 2N SmartGate).
- Gateway for extension line of PBX – Link free extension line of your PBX to FXO interface on 2N SmartGate. FXS interface remains unconnected.
- Gateway for trunk line of PBX – Link free trunk line of your PBX to FXS interface on 2N SmartGate. Program PBX to route all GSM calls to SmartGate. Incoming calls from GSM network will be routed to PBX. You can connect a standard telephone, an answering machine or any other FXO–interface terminal to 2N SmartGate. Outgoing calls from phone will be routed to GSM network, incoming calls from GSM will ring on the phone. Optionally you can connect analogue fax (special model of 2N SmartGate).
- Gateway for both, trunk and extension, lines of PBX – 2N SmartGate is very flexible thanks to its three routing tables. You can connect trunk and extension lines of one PBX to proper connectors on SmartGate. You can program the complex as follows: outgoing calls from PBX will be routed through trunk line to GSM network. Incoming calls from GSM will be routed to extension line of PBX. This configuration is suitable for PBXs which are not able to dial–in on trunk lines.
