Description:

AVSK-1U-06 crew intercom system is intended for organizing internal and external communication between subscribers of a unified system of a modernized SPG (self-propelled gun), organizing digital communication channels for the interaction of equipment and object devices both via WCL (wired communication line) and radio channels.

Specifications

AVSK-1U-06 crew intercom system provides:

• connection of seven crew members (two of them at a distance of up to 10 m);
• connection of two channels of R-168-25U-2 radio station for the exchange of voice information via С1-ТЧ interface, for data exchange between data communication equipment through the radio station via С1-ФЛ interface, for controlling the radio station and monitoring its performance via RS-232 interface;
• simultaneous connection of up to two independent channels of data communication equipment via С1-ФЛ interface;
• simultaneous independent exchange of information with external subscribers via two wired communication lines and two radio communication channels;
• possibility of line switching with internal and external subscribers by the commander of the object or the gunner;
• individual selective two-way telephone communication with sidetone monitoring between the commander of the object (gunner) and external subscribers;
• access of the driver to external radio communication via С1-ТЧ interface of any of the two channels of the radio station;
• individual selective two-way telephone communication with sidetone monitoring between the commander (gunner) and crew members of the object;
• broadcast internal two-way telephone communication with sidetone monitoring between all crew members of the object;
• possibility of constant listening to the signals of the external radio communication receiver by the commander of the object, regardless of internal telephone communication modes;
• light indication of calls arriving via radio and two lines with their duplication by a sound signal in the equipment of the selected subscriber;
• light indication of the conversational state of communication lines;
• transmission of a call signal to external subscribers via a wired communication line, formation of a control signal for transmitting a frequency signaling to a radio station, as well as control of sending a call signal to the communication channel on the initiative of the commander of the object or the gunner;
• individual adjustment of the volume level of the signals being listened by each crew member of the object (with the exception of the voice notification module signals);
• operation in conditions of acoustic noise up to 120 dB;
• word intelligibility of at least 90%;
• generating a voice message on a command coming from an onboard electricity supply system, and listening to it by crew members of the object, regardless of the mode of operation of the device;
• continuous operation for at least 48 hours;
• connection of two breast switches of projectile loaders via linear turret board;
• communication channels reservation;
• technical and organizational compatibility with the object's voice communication system;
• flexible configuration with the possibility of implementing new functions and modes depending on the composition, functionality and characteristics of the object without changing designs and system solutions.

Applicability

SPG 2S19 Msta-S, SPG 2S3 Akatsiya, self-propelled mortar 2S4 Tyulpan, SPG 2S7M Malka.
