U-SYS IAD108 Integrated Access Device Chapter 1 System Overview
Chapter 1 System Overview
1.1 Introduction to Product
Integrated Access Device (IAD) is an important component of
the Next Generation Network (NGN).
Huawei’s IAD108 is an Access Media Gateway (AMG) based on
the technologies of Voice over IP (VoIP) and Fax over IP (FoIP). It
not only provides efficient and excellent voice services on the
world-wide IP network (the Internet or Intranet), and also provides
small-capacity VoIP/FoIP solutions for enterprises, users in
communities and companies.
IAD108 adopts the box design, and is usually installed on the
desktops or hung in the corridors. The appearance is as shown in
Figure 1-1.

1.3.2 Software Structure
The software system of IAD108 consists of the main CPU
software and DSP software of the CSP. As the core of IAD, the main
CPU software implements the call control of the whole system,
management and maintenance function and forwarding of media
flow. The DSP software mainly implements the coding and decoding
of voice, detection and generation of Dual-tone Multifrequency
