SU87325A1 - A device for receiving a call from a called GATS subscriber of a decade-step system on a PBX or URTS - Google Patents

Description

A device is offered for receiving a call from a called subscriber, a GL7C decade-step system on a PBX or URTS in which .to increase the usefulness of the GATS in a set of relay lines to the wire and a connecting line connects a high-resistance relay that controls bouncing signals in the direction of the PBX string pair (or URTS) from the urban subscriber side. Moreover, if the RSL kit is included in the regular subscriber kit of the first GATS prediscaster, a plus must be marked on the wire and the connecting line, on the wire b minus GATS battery.

FIG. 1 shows a device for the transmission of a switch as applied to switch sets CBS2 of the Moscow circuit; FIG. 2 - a device for the transmission of the release in relation to the ULGS machine system; in fig. 3 - to the ULGS of the ten-step system of special supplies.

The device for receiving a release from the called GATS subscriber consists in the following: in the RSL kit, the outgoing connecting line of the switchboard installation, when it is disconnected from its subscriber, to the wire and the connecting line is connected for a short time with a high resistance O (with a winding resistance of 10,000 ohms).

Since the minus from the supply relay will come from SHI over the wire a, the relay O will work and block through its own contact RSL PBX.

When the switch subscriber releases, the YAR impulse relay then releases the SR relay and C relay, which the SP connects the relay to the wire a. Relay O will work and contact O /// connects

choke 300 ohms minus. Due to this, the breaker relay of the OR2 cord pair will remain energized and breakaway + the OL2 light bulb will not light up. When the called PBX subscriber bounces off, the O relay will release and the OL2 lamp bounces off, since the switch will receive a full bounce (on both lamps).

In the second and third schemes, if the switch is cleared by the PBX, it will release the relay A, then the relay O will go off, which will break the wire and this will prevent the connecting line from being picked up before being picked up by the called subscriber.

Subject invention

A device for receiving a call from a called subscriber's PBX in a decade-step-by-step system on a PBX system, or RTS, characterized in that, in order to increase the efficiency of the PBX system, a high-resistance relay is connected to the wire in the connecting line signals from the side of the PBX (or URTS) from the side of the urban subscriber, and if the RSL kit is included in the regular subscriber kit of the first tenant, PBX and the connecting line should be marked plus, and on the wire b - minus the battery G PBX.
