Fax ATA Installation Guide

Modified on Mon, 6 Oct at 9:31 AM

Overview

The Pangea Fax ATA allows you to connect a traditional fax machine to your internet-based fax service.

Once connected, your faxes will send and receive through your VoIP network rather than a phone line.

• 1 × Pangea Fax ATA (Grandstream HT801 or HT812)

• 1 × Power Adapter

• 1 × Ethernet Cable

• 1 × Telephone Line Cord

✅ Ensure you have:

• An active internet connection (router or switch port available)

• Your fax machine powered and ready

• Do NOT connect the ATA to a wall phone jack — it connects only to your fax machine

PORT	LABEL	FUNCTION
LAN / WAN	“LAN” or “Internet”	Connects to your router or switch
☎ PHONE / FXS	“Phone” or “Port 1”	Connects to your fax machine
POWER	“DC 12V”	Connects to power adapter

(illustration placeholder: network diagram showing router → ATA → fax machine)

1. Internet: Plug one end of the Ethernet cable into your router or network switch, and the other end into the LAN/WAN port on the Fax ATA.

2. Fax Machine:Connect a telephone cord from your fax machine’s LINE or PHONE jack to the ATA’s FXS port (Port 1).

3. Power: Plug the power adapter into the ATA and then into a wall outlet.

4. Wait about 2 minutes — the Power and Internet lights will turn solid, and the Phone light will illuminate once the fax machine is detected.

✅ If both send and receive tests pass, your installation is complete!
