If you have Comcast phone service its a constant 89.5v ac at the phone box. Now imagine what you could run with that.... I can't believe someone actually makes products like that. |

Read the info near the bottom. Backorders are currently running six to eight months. Due to the nature of these products and the terrific demand, we will charge your credit card as soon as the order is placed. Should you wish to cancel your order, or if the products should prove to be on backorder or unavailable for more than twelve months, we will cancel your order and refund half of the monies paid. :) |

89.5 constant? I don't think so. If you recall back in the 70's when "Princess" phones were popular, a small transformer was required to light them up. I can't remember exactly but I believe when a phone is on-hook the line voltage is around 6 volts DC with ringing voltage about 90 volts AC, and in-use voltage about 24 volts DC. --Deeply Shrouded & Quiet --KD7YVV, Kirkland, ARES #154 |

Standard telco loop voltage is 48volts on-hook. Off-hook will typically drop it to around 12 volts depending on the current consumption of the balancing network. Standard ring is 90 volts at 20 hertz. The available current is so miniscule that its not worth spending money attempting to do something with it. |

Sorry fellas...89.5 constant AT THE PHONE BOX. Because of this we must use what are called drop checks. They are filters. 1 at the pole 1 at the phone box/NIU. We are required to use them because of the constant voltage. If the line is cut they stop the voltage. We can't use the typical telco setup. Thats why AT&T Broadband is no more.....way too much money to make it work. Comcast hasn't promoted the phone service since they took over. They have been busy trying to find a way to make money on what AT&T did....hence VOIP...and yeah its coming. I think we were told early next year. If you have a small flathead screwdriver and our phone service, open up the service side and check the voltage AC. On the customer side of the box you will see between 43 and 49 DC Thanks |
