Telephone question

Started by Jim Thompson June 10, 2014
Anyone have a clever solution to this problem...

I have a one-line telephone, but two telephone lines in the house.

Is there some way, perhaps with relays to recognize which line is
ringing and have the one-line phone connected to the ringing line?

(It's a honey-do problem... you know... "pretty phone, don't throw it
away" :-)

I love to cook with wine.     Sometimes I even put it in the food.

easy, do you want the 'full-blown-solution [schematic] for a way to either prevent picking up a line in use, or a way to notify a line in use also?

Nothing fancy, just allow the phone to answer the one that is ringing. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

automatic, or need to know which line?

Automagical... whichever line rings (first), picking up phone answers the first one that was ringing. ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: skypeanalog | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

Radio Shack used to sell such a device. IIRC it's basically a latching relay with the coil(s) activated by the ringing current. Dunno if they or anyone else still markets something like this... I bought ours back in the late 1980s.

Search for "2-line switch". These guys in Taiwan have one that looks to meet your request, and apparently they'll ship. http://www.mycomsolutions.com/ax520/ax520.htm Best regards, Spehro Pefhany -- "it's the network..."

I have, in storage, a commercially produced telephone accessory [cost about $50] to enable a single line telephone to operate two telco lines. Although the device could sit in view showing which line Ring indicators, 'line in use' indicators, AND HOLD indicators multi color LEDs; it could be placed out of sight because it had no buttons. You operated transitions by using ON HOOK/OFF HOOK, or 'flash' button on the keyboard. Very handy to place a present conversation on HOLD in order to answer the other line's incoming call. Plus, if the other person terminated the call while on HOLD; the unit sensed the hang up and released the line.

Sounds straight forward; a couple of ring detectors, driving a latching relay. ?-) =20
