This Information Factory course "Introduction to
ISDN, ATM and Broadband Transmission" is a continuation of our earlier course "Introduction to Digital Transmission." In the first course we described how the world's telephone networks were moving from their analog transmission methods onto a completely digital transmission network. In this training course we are going to describe how the telephone networks are extending the digital interfaces into the customer's homes and offices under a new service called "Integrated Services Digital Network" or ISDN.
