Support two phones on one port with a Phone Adapter.
Save time, money and the hassle of installing a second line with a Siemens Phone Adapter. The Phone Adapter allows one port to support two Optiset E phones, each with its own extension, reducing the number of ports on your system. Use the Phone Adapter wherever a second cable run is impractical or difficult and a secondary phone is needed for voice-only applications in the next room or office-any site up to 300′ away. The connection to the secondary phone from the primary phone is by a standard RJ11 cable between the Phone Adapter and the second Optiset E. Cannot be used with the Analog Adapter.
Requires non-routine software change and power supply.
