N+1 Automatic Change Over Controller, WCU-6+1 and MTX-AUD-6+1 N+1 Fully Web and SNMP WEB Control Unit System

TEKO Broadcast offers extremely reliable N + 1 systems like a complete turnkey solution with rack integrations personalized and compact.N+1 Automatic Change Over Controller can manage up to 8 FM programs (up to 8 + 1 systems). Thanks to the use of the standard SNMP protocol, any anomaly of the main transmitter is detected automatically by the switch of the automatic shift controller Nf + 1 that changes to the backup transmitter. Our system smart and all the parameters related to the limits of time, program priorities, switching conditions, etc., are fully configurable.
The controller is fully equipped with all interfaces security loop, CAN bus and RF switches (from N to 1 / 5/8). The N+1 Automatic Change Over Controller offers a full control through its intuitive web interface, and for local and manual operation, front panels offer easy access quick and easy via displays, status indicators and buttons for manual change or other actions.


Components of Automatic Change Over Controller N + 1

An N + 1 system is made up of:

  • N main FM transmitters, of any power, in D.E. or 1 + 0.
  • A standby transmitter (or +1) that must be able to operate at frequencies and configurations of the N main transmitters.
  • N Coaxial switches that allow the exchange of RF signals to the antenna, between the main transmitters and reservation.
  • A N + 1 UCA (Automatic Switching Unit) capable of manually / automatically and locally / remotely manage the system N + 1.
  • An input preselector that allows selection and switching the audio signals of the N transmitters to the backup transmitter.
  • Interconnection kit between all the elements that make up the N + 1 system. This kit consists of the specific wiring and any additional card, such as those described in the section Minimum specifications of the interlock circuit of the N + 1 system. Auxiliary cards.
  • An artificial charge whose power capacity is 25% greater than the greater of the powers of the N transmitter system.
  • OPTIONAL: RF sensors, external and independent of the transmitters, capable of remote signaling by contacts free of voltage both correct and incorrect RF levels (both independently adjustable). Additionally it would be it is desirable that these sensors be capable of delivering a direct and reflected power telemetry of the system. East external element, it is only considered necessary for cases in that the N main transmitters do not have by contacts this information.

Description N+1 Automatic Change Over Controller

The system is governed by a N+1 Automatic Change Over Controller, which supervises the operation of the rest of elements.

In the event of a N transmitter failure, this System must be capable of act on: the main transmitter that has failed, the reserve (+1), the coaxial switches and the audio preselector, to get the reserve transmitter to broadcast on the antenna (or B.E. of the multiplexer) corresponding to the transmitter that has failed, with all parameters of power, frequency, program (audio) and any other transmitter configuration parameters the one who substitutes.

It must be taken into account that in a chain of N transmitters there can be different powers for different services. The standby transmitter must be capable of operating at each case with all the correct parameters.
