In brief
The DS-Micro switch is a compact matrix switch contained within a 1u high 19” custom built housing. Each mini switch is designed to house a maximum of 4 two channel port cards although the unit can be sub-equipped for smaller capacity systems.
There is only one variety of switch cards in the system and they can be programmed to be either a channel port, or an operator port.
The cards operate using our own DSP software code which greatly reduces the component count, thus providing a very cost effective method of providing a multi operator, multi channel control system.
System communication
All of the system cards communicate with each other via a dual bus system controlled from one of the switch cards acting as a master controller running an arbitrator routine. Any one of the cards can function as the master controller thus ensuring a high level of redundancy within the switch system.
System wide broadcast messages enable all elements to be synchronised with systems events such as call status, channel occupancy, call alerts and alarm messages.
The switch node communicates with connected operator consoles via a serial data link. Another option is for remote operators to be routed to the switch utilising voice over IP technology. This will allow operator controllers networking via the internet or local intranet facilities.
