2.1 Connectors

There are five connectors on AX-112, and you can find them on the two side panels. These two side panels can be distinguished by the arrow icon, the upward arrow indicates the WAN side, while the other downward arrow indicates the LAN side.

2.1.1 WAN side connectors

PWR WAN

PWR PSTN WAN (FXO)

DC power jack

Use the universal power adapter included in the package. The adapter is a high quality switching power device which accepts 100~240VAC input, and 5VDC output with 2A rating. If you have to use a substitute power adapter, use an adapter of good quality and with the correct rating. Incorrect voltage adapter output may damage the AX-112, and poor quality adapter may induce unacceptable ripple noise to the phone set.

RJ45 WAN

Normally, this port is connected to your broadband Ethernet port which could be xDSL, cable modem or your office LAN. You have to assign an IP to the WAN port of AX-112, or enable its DHCP client to get an IP from your DHCP server.

RJ11 line port

The line port is used for connecting to the PSTN line. It is also called as the Foreign Exchange Office (FXO) port. This line port on AX-112 only has bypass function without the DAA circuit. This means that it can relay the incoming call from PSTN to the phone set connected to the phone port, but the VoIP call can not go through by this line port.
