BSTS-5 Series 3
Digital Communication Unit
Description
BSTS-5 Series 3 digital communication unit
BSTS-5 Series 3 is the common Latin catalogue form of the Russian aircraft designation БСЦ-5 серии 3. Aviation inventories identify it as a digital communication unit. The “Series 3” suffix is part of the product identity and must be retained because another series may use a different circuit, interface or connector arrangement.

Function in onboard digital equipment
The block belongs to the communication and interface layer of aircraft avionics. Its supported description is limited to the exchange or transfer of digital information between cooperating units. It should not be presented as a radio communication set: the word “communication” here describes data interaction inside onboard equipment rather than voice transmission.
System connections
In service, BSTs-5 Series 3 must be evaluated with the source and receiving digital blocks, power supply, aircraft harness and the logic described in the system documentation. A related interface product is the BSDT (1477B) trajectory-sensor interface unit, but a shared role in signal exchange does not make the two units substitutes.
Identification and compatibility
The exact aircraft and subsystem were not reliably established in public technical documentation. No platform, supply voltage, coding protocol, connector pinout, dimensions or mass has therefore been assigned by analogy. Confirm БСЦ-5, Series 3, the assembly or drawing number, connector keys and the installed-system reference from the aircraft records before selecting a replacement.
Inspection and supply
Incoming inspection covers the enclosure, connectors, contacts, mounting points, seals and complete nameplate. Functional testing requires the approved Series 3 procedure and known interfaces. For a quotation, provide the Cyrillic or Latin marking, aircraft and system if known, quantity, condition, required documents and delivery-set requirements. Related equipment is collected under Electronic Control Units.
