Automatic Telephone Line Switch ATK-01

The automatic telephone line switch АТК-01 is used for determination of the type of an entering call (phone call or computer modem call) and its redirection correspondingly on phone or modem connected to a heat meter.

Instead of user's phone wiretap of the second modem connected to the second heat meter is possible.

The switch provides the functioning of one user's telephone line on two devices - a telephone and a modem. Thus user's phone works as the primary device in a usual operating mode for it and the modem - as the secondary device only from an entering call.
