Installing ATA Adapter
Article #8379

1. Connect your analog phone via an RJ11 connector to the port labeled “Line 1” on the ATA.

2. Connect an RJ45 Ethernet Cable from port labeled “Internet” to a WAN/LAN (DSL Modem or Cable Modem, or Router connected to the modem). The “Ethernet” port can be used to “daisy-chain” in a computer that requires an Internet connection.

3. Connect the ATA to its power supply. Allow the ATA to power cycle and completely turn on. The phone should now have a dial done and be ready to place or receive calls.
