APN1 Voice for Data Professionals Ver 0-2.doc

This course, Voice for Data Professionals, has been specially designed for data communications professionals who need to understand the key technologies, services, concepts and terms of voice communications. From telephony basics to the sophistication of today’s "wonder" digital networks that combine voice, video and data traffic, we cover the user’s concerns, as well as private, public and hybrid networking solutions. The course will equip you to examine:

• How voice is transformed into an electrical signal.
• The benefits and limitations of digital versus analogue transmission.
• Signalling System #7, SONET, ATM and T1/T3
• What constitutes Customer Premise Equipment (CPE)
• The rapidly emerging fields of Cellular mobile technologies (CDMA, GSM, GPRS, EDGE, W-CDMA and CDMA2000)
• CTI/Computer-Telephony Integration
• Voice communication network management
• Voice over IP (VoIP) as well as Voice over Frame Relay and Voice over ATM
