Special communication equipment

Telephone switches “ATP-1” “ATP-2”

These models provide remote control of radio station with help of a forcestick placed on handset. “ATP-1” and “ATP-2” are supposed to be used for mutual switching of local loop between basic four- or two-wire phones and four- or two-wire phones of a secretary.
Pins of these switches expect the resistive load - up to 6 W, current strength - up to 80 mA, DC voltage – up to 75V and AC voltage – up to 120 V under frequency 25(50)Hz.
These telephones have an electrostatic and magnetic screening. They must be used in enclosed heated spaces that provide following:
- Ambient temperature from +5 °С to +40 °С;
- Air humidity up to 80% under +25 °С;
- Atmospheric pressure from 84 to 107 kPa (from 632 to 805 mm of mercury column)

These switches have following modifications:
- for one four- or two-wire lines
- for two four- or two-wire lines

ATP`s have an electrostatic and magnetic screening. As switches for special communication they provide following:
- breakless connection of line while switching;
- additional resistance to direct current
 
Phones “Nephrite” and “Selenite”

These models with/without keypad expect to be used for communication in special stationary networks. Power supply is performed through automated line from constant-voltage source of ASC or switching equipment. Phones must be used under following conditions:
- Ambient temperature from +5 °С to +40 °С;
- Air humidity up to 80% under +25 °С

“Nephrite” and “Selenite” have an electrostatic and magnetic screening. There are following modifications:
- for two-wire lines (including ASC “Kvant”) - “Nephrite-2-G-ATS”, “Nephrite-2-G-CB”, “Selenite-2-G-ATS”, “Selenite-2-G-CB”;
- for four-wire lines - “Nephrite-4-G-ATS”, “Nephrite-4-G-CB”, “Selenite-4-G-ATS”, “Selenite-4-G-CB”;

Apparatus “Nephrite” and “Selenite” have control function against unauthorized and illegal access.
 

“Abonent-5”

This telephone with rotary dialer is supposed to be used in two- and four-wire modes in stationary networks with short lines. Power supply is performed from constant-voltage source of ASC with voltage equal to 60V or switching equipment. “Abonent-5” has tone double-frequency calling device, electrostatic and magnetic screening. There are four modifications:
- for two-wire lines - “Abonent-5-2”, “Abonent-5-2G”(with National Emblem of Russian Federation on the front panel)
- for four-wire lines - “Abonent-5-4”, “Abonent-5-4G”(with National Emblem of Russian Federation on the front panel)

“Abonent-5M”

This telephone must be used under +5°С to +40°С and air humidity up to 80% under +25 °С.
The apparatus is possessed of keypad and expect to be used in four-wire lines in special stationary networks and at objects where confidential talks are taking place. Power supply is performed from central voltage source of ASC or switching equipment. “Abonent-5M” has electrostatic and magnetic screening. Dialing of number is performed in decade or multiple-frequency code with help of keypad that is included into the transmission channel loop.
This phone has tone double-frequency calling device that can be included into the transfer loop and receive loop as well.
Weight : no more than 3,5 kg
Measures: 232x167x97 mm.

“AT-3031”

This telephone is supposed to be used in ACS`s and MCS`s networks in four-wire lines with resistance up to 900 Ohm. “AT-3031” has electrostatic and magnetic screening, tone calling device, receiving and transmitting amplifier. This item has two modes: “MT” – with handset, “AG” – with device YA-96 (headset). Provides remote control of radio stations.
There are two models / four variants of this phone:
- АТ-3031 АТS
- with headset YА-96
- without headset YА-96
- АТ-3031 CB (without dialer)
- with headset YА-96
- without headset YА-96

The item expects usage under -30°С до +50°С in MCS`s networks, -10°С to +50°С in ACS`s; air humidity 98% under t + 40°С. The phone has both wall mounting and desktop case and can be placed in movable objects. The handset is additionally held by special holders.

“P-171D”

This telephone with rotary dialer is supposed to be used in two- and four-wire modes in ACS`s and MCS`s networks with voltage from 60 to 24V in short lines. The phone expects usage under -10°С до +50°С and air humidity 98% under t + 40°С. “P-171D” has electrostatic and magnetic screening and there are two models:
- “P-171D-ATS” (with rotary dialer)
- “P-171D-CB” (without dialer)

The phone has both wall mounting and desktop case and can be placed in movable objects.
