900 Mhz Experiment (Con’t)

 

900 Mhz Experiment (Con’t)

Once the Cordless phone part of the project was complete, we went on the the cellphone interface.  I bought a device called a “Cell Phone Docking Adaptor”.  Its purpose is to link a cell phone to a normal landline telephone system.  This is the XLink BT box.  It connects to up to 3 cellphones (for three lines) and one landline phone.  It is not designed to hook to a system that is still connected to a live phone line.

 


It has a power connection, and a phone line output connection.  In addition, there is a USB port that is only used for applying updates (like for new models of phones).  The cellphone connection is via Bluetooth only.  No cable needed there.

 


When you press a button on top for one of the lines, the XLink searches for a Bluetooth signal.  You set up your phone to accept the connection.

 


And once you accept the connection, you just set down the cellphone nearby the XLink box, and use the phone attached to the line to make and receive calls via your cellphone connection.  Each line has a distinctive ring, and caller ID info is forwarded to the handset.  I can’t confirm that the caller id part works, as the display is bad on the cordless handset.

 


So there it is, the call comes in over the cellphone, gets forwarded to the XLink box, gets forwarded to the house phone (cordless phone in this case) and is answered by you.  Or you pick up the cordless handset and press talk.  You get a dialtone and dial your number just as you would from the cellphone.  The call is completed via the cellphone service. I’ll do extensive range testing next time we go up to the ranch, where we have much more wide-open spaces.
