Telephone Interface
There are 30 RJ45 connectors on back panel, support 1-30 analog line telephones
access. The device supports two interfaces: FXO and FXS. If this device is built-in
FXO module, the interface is FXO interface, you can insert the phone line that that
through switch into FXO interface. If this device is built-in FXS module, the interface
is FXS interface, you can insert it into telephone directly.
One RJ45 connector can support 1Channel analog telephone access (telephone
interface), PIN defined as follows:

Power
Device supports AC220V, DC -48V and DC24V (Optional)
If you use AC220V power, you should connect device power input port with power
socket by using random power line to provide AC220V power device.
If you use DC to supply power, DC-48V as an example, please connect as follows:
“FG” polarity Connect ground

“-48V” polarity Connect power negative polarity
“+48V” polarity Connect power positive polarity
Note: Device has polarity protection measures. If positive and negative polarity is
connected reversely, device will not damage, function well and ease of installation and
maintenance. (The power contains DC48V, DC -48V, DC24V, DC -24V, and so on).
