2.4 Telephone line connection

DialThru gateway – basic connection

Phone set is normally connected to extension line of PBX. Wire up 2N^® SmartGate UMTS between phone set and PBX. Link extension line of PBX to FXO interface and phone set to FXS interface on SmartGate UMTS. If FXO interface of 2N^® SmartGate UMTS is connected directly to PSTN, you can connect only equipment that is in compliance with the essential requirements and other relevant provisions of Directive 1999/5/EC to FXS port.

Gateway for extension line of PBX

Link free extension line of your PBX to FXO interface on SmartGate UMTS. FXS interface remains unconnected.

Gateway for trunk line of PBX

Link free trunk line of your PBX to FXS interface on SmartGate UMTS. Program PBX to route all UMTS/GSM calls to SmartGate UMTS. Incoming calls from UMTS/GSM network will be routed to PBX.

You can connect a standard telephone, answering machine or any other FXO-interface terminal to SmartGate UMTS. Outgoing calls from phone will be routed to UMTS/GSM network, incoming calls from UMTS/GSM will ring on the phone. 

2N^® SmartGate UMTS is equipped with the FSK-based CLIP and so it is advantageous to connect a terminal that is able to display or process the CLI. You must activate the function on SmartGate UMTS.

Gateway for both, trunk and extension, lines of PBX
