4. Setup Instructions
Follow these steps to set up your Linksys PAP2 Phone Adapter:
- Connect to Your Network: Plug one end of the Ethernet cable into the 'Internet' port on the PAP2 adapter. Connect the other end of the Ethernet cable to an available LAN port on your router or gateway.
- Connect Your Phones: Plug your analog telephone(s) or fax machine(s) into the 'Phone 1' and/or 'Phone 2' ports on the PAP2 adapter using standard telephone cables.
- Connect Power: Plug the power adapter into the 'Power' port on the PAP2 adapter, then plug the power adapter into an electrical outlet.
- Verify Status: Once powered on, observe the LED indicators. The 'Power' LED should be solid green. The 'Internet' LED should also be solid green, indicating a successful network connection. The 'Phone 1' and 'Phone 2' LEDs will illuminate when a phone is off-hook or during an active call.
- Service Activation: Contact your chosen VoIP service provider (e.g., Vonage) to activate your service and configure the adapter. You will typically need to provide the MAC address of your PAP2 adapter, which can be found on a label on the bottom of the device.
5. Operating Instructions

- Receiving a Call: When your phone rings, pick up the handset to answer the call.
- Independent Lines: Each phone port (Phone 1 and Phone 2) operates independently. You can have two separate conversations simultaneously using two different phones connected to the adapter, each with its own phone number if configured by your service provider.
