VoiceCom is an Ampcontrol designed multi station audio communication system
that incorporates pre-start alarm, controlled start/stop as well as voice messaging
and intercom capabilties. The system comprises two main components: the VCA
VoiceCom controller and the VAA VoiceCom Amplifier Field Units. The units are placed
at the control room, shaft top, shaft bottom and along the tunnel.
The system also features:
Long distance communications on a single twisted pair
Multi-drop two wire network
Inbuilt battery back up

The underground digital network is the backbone of the system. It provides the
transport for the tracking, voice, video, corporate data and control system
information. Each of these traffic types is assigned to its own Virtual LAN (VLAN) so
each traffic class is segregated and appropriately prioritised.
It offers:
High speed underground digital Ethernet network
Tracking of personnel and assets using Wi-Fi tags
VoIP
Voice communications between workers within each underground development
area and the control room
Digital/analogue leaky feeder radio
CCTV and thermal video network
Communications system
