Description

The subject matter of the invention is: p; p; p; p; p; i ochsgel telephone set-1 Tr; B 1st battery (CB).

In the known 1–1 telephone sets of the CB system, the call to the station is accomplished by closing the circuit through the telephony linkage lever group {removing the microtelephone tube from the lever of the apparatus) by following the disconnecting path of the chain (lowering the KpnTe .Te j (i: iOHi oi tube) lever apparatus).

The presence of low insulation resistance of the linear structures of the optical circuit and the circuit of the telephone apparatus does not always lead to the release of the core of the corresponding station relay.

The proposed device, which is installed in a telephone unit with a central bank unit, differs from the switchboard (pg. That B) 130P. It is sent to the station by sending a short-duration e.: | electric impulse at the microtelephone handset from the lever of the device, and when receiving the same impulse after the AP -:; -: ps) tel (bo

polo / ken pa pi5i4ar te.phone device.

The device inuiy.ibcnoe provides the device with sigia at the station, t (ringing and calling when the telephone is often connected to one of the facilities that are less than 10 k.tot.

On (. 1 p. O, the device is de-pulsed with the ipy6i e microtelephone removed from the lever of the apparatus; on chii: -. 2 - npi lowering the tube on the lever of the apparatus; fig. 3-pm downy tube.

While the handset is on the lever of the telephone apparatus, the wedge i lever1a 2 is located in the down position and nmg | ice contact; (PC) - / - D) 1) azo-twists.

Crp-, after removing the tube from the lever of the annarate wedge, found pi-n | s on the rod of the lever, comes 1,; iBH i einie. go up and in the period of a short stay the springings are grouped by IR on BtnCTyHC K.Uiiia, the latter closes the IR. P) this time closes the chain, activating the corresponding station relay, which is blocked by a mechanic method. By

When the lever of the apparatus of the upper position is reached, the spring of the IR block, the digger from the protrusion and the circuit of the station relay is opened.

In pi-boom, when the microtelephone is placed on the handset of the apparatus, the lever wedge makes a reverse movement during the short period of the IR spring on the wedge projection, for the second time, closes the IR and sends a second impulse to the station, from which the corresponding relay is triggered, violating the mechanical key; . The impulse device in the apparatus can be used when the apparatus is switched on in the station of a special system, which provides for the acceptance of pulses for call recall and call back.

Subject invention

Lever overflow,: (n) chat.that telephonio on apnarata central battery (CB), with the fact that, in order to carry out a reliable call and call for phone transmission over linear structures with an insulation resistance lower than 10 kilo, a contact device is used to send a short-term pulse to a switch with a pulsed control by the system of short circuits by short-circuiting two contact springs when the lever moves upwards, call station springs and the same contact circuit closes down when the lever moves down fight.
