Onboard Communications

Our on-board communication system is an extension of our digital public address system that allows on-board private communication such as between passenger and driver.   Our on-board communication system is also integrated with our Pathplayer passenger information system and can utilize in-car LED signs/public address for friendly call alerts to on-board staff.

Our on-board communication device sends bi-directional digital information over our Digital Audio Backbone.  The data packet routing is automatically managed by our advanced Digital Audio Backbone controllers. 

SYSTEM FEATURES

Key features of our onboard communication system are:

• Provides private link between driver and onboard staff/passenger.
• Our on-board communication device can be integrated to emergency stop trigger if required.
• Offers both full duplex and half duplex modes of communication.

• Friendly call alerts by using signs and pre-recorded voice over public address system.

SYSTEM SETUP

• Complete out of the box onboard communication system.
• Ability to retrofit with third-party or existing Public Address system.

DEVICES

Our Digital Audio Backbone Controller provides smart digital audio communication pathway for our Digital Public Address device to reliably communicate bi-directional in a de-centralized control fashion.  These Audio Backbone controllers discipline the over-all data traffic by utilizing packet addressing and prioritizing.  

Our Digital Audio Backbone controllers are well engineered with in-built advanced data transmisison and data compression techniques allowing the system to work realiable without the need to installing high-speed data wiring.  This features make our Digital Audio Backbone Controllers suitable for retro-fit projects in upgrading outdated analog on-board communication or analog public address system as the client can utilize existing wiring and peripherals resulting in time and cost savings.

To summarize these controllers offers back-end intelligence for on-board public address and on-board communication system.  The front end peripherals such as public address amplifiers, automated passenger information announcements are integrated to the Digital Auido Backbone in a plug and play manner.
