BS EN 62365:2009

What is this BS EN 62365 - Digital audio over ATM networks about?  

BS EN 62365 discusses digital audio and digital input-output interfacing with a focus on the transmission of digital audio over asynchronous transfer mode (ATM) networks. BS EN 62365 specifies a means to carry multiple channels of audio in linear PCM or IEC 60958-4 format over an ATM layer service conforming to ITU-T Recommendation I.150. BS EN 62365 includes a means to convey, between parties, information concerning the digital audio signal when setting up audio calls across the ATM network.  

Note: BS EN 62365 does not specify the physical interface to the network. 

Who is BS EN 62365 - Digital audio over ATM networks for? 

BS EN 62365 on digital audio over ATM networks is useful for: 

• Manufacturers of products that provide audio output (televisions, phones) 
• Audio equipment manufactures  
• Audio programmers  
• Music producers 
• Sound technicians 
• Recording and dubbing studios  

Why should you use BS EN 62365 - Digital audio over ATM networks?  

ATM, also called broadband ISDN, provides a service similar to ISDN, but with the capacity of 

each call being specified by the caller. ISDN provides telephone call connections of a fixed capacity that carry one 8-bit value per 125 μs; when a call is set up, its route through the system is chosen, and the switches that route the data are configured accordingly. 

BS EN 62365 describes means for the transmission of professional audio across digital networks, including metropolitan- and wide-area networks, to provide the best performance with regard to latency, jitter, and other relevant factors.
