Radio Equipment Engagement and Monitoring Quiz

What is the purpose of the Best Signal Selection (BSS) facility?

The Best Signal Selection facility detects the best audio radio signal quality in a group of many.

What are the criteria the BSS algorithm can be based on?

The BSS algorithm can be based on signal-to-noise ratio (S/N) or RSSI (Received signal strength indicator) or a mix of them.

What is the role of the Voice Communication Routing in the system?

Voice Communication Routing directs voice communication traffic to the appropriate destinations.

Describe the basic function management capabilities of the radio section interfaces.

The radio section interfaces provide audio reception with AGC, audio transmission, recording output, PTT command, squelch detection, external facility control, incoming status management, in-band signaling, best signal selection via DSP, and phantom signaling. Signup and view all the answers

How are remote radio sites interfaced with the central VCS in the MULTIFONO® system?

The 2M/MPI modules in the central VCS establish connections to VoIP ED137 Radio Receivers/Transmitters and Transceivers at remote sites through MPLS WAN(s) and/or E1 network(s). Signup and view all the answers

Describe the redundancy mechanism for interfacing remote radio sites in case of failure of the primary VoIP ED137 equipment.

At remote sites like Agatti and Port Blair, the 2M/MPI modules in the VCS establish connections to GVS Gateway Units, which interface with the analog 4W E&M Radio Equipment, providing redundancy. Signup and view all the answers
