This adapter plugs into an existing modular wall outlet and provides two identical connections. If the wall outlet is a single line, you are provided with two identical single line connections. If the wall outlet is wired for two-line operation, you are provided with two multi-line connections. This adapter will allow a satellite receiver and a phone to share the same phone line. Keep in mind that connected devices to a single line cannot be used concurrently as this adapter does not provide two independent phone lines, it simply splits the single line wire. It is available in ivory.
