The Outdoor DSL POTS (Plain Old Telephone Service) Splitter allows voice and data signals to travel over the same telephone line and be separated at the customer premise. The 649A1 splits the incoming signal to provide separate outputs for filtered voice (phone) and ADSL (data) in the form of screw terminals. The Outdoor POTS Splitter is designed to be mounted on a wall or conduit next to a Network Interface Device (NID).
