CADN Digital Subscriber Channel Standards

The central vision of current telecommunications research and developments is an integrated network that will use shared resources to convey all types of information to people and machines everywhere. Acting within the CCITT, the world's information technology manufacturers and service providers are making impressive progress in setting standards for Integrated Services Digital Networks (ISDN)[1]. Users and operating companies will be confident that the hardware and software they acquire will be compatible with corresponding products regardless of manufacturer. Similarly, the manufacturers will be assured of global markets for their products.
