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.
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.
RJ4 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.
