Description

This work explains telephone switching systems and how the technology is evolving to accommodate voice-over-IP traffic. Unlike data networks, telephone networks are proprietary. They're purchased as complete systems and are hard if not impossible to modify. Allan Sulkin explains how to acquire, deploy and maintain a system with all the features needed to support essential new applications, and how to get optimal performance from the system you have.
