Configuration
IMG consists of Engines – software units that can be executed on different hardware platforms and are connected by UDP/TC/IP protocols. This organisation enables big flexibility and skalability.

- ME (Media Engine): is working on voice coding/encoding
- SE (Signalization Engine): is dealing with signalization
- AE (Application Engine): controls software applications and functions
- TE (TDM Engine): is dealing with POTS
When IMG is a part of Аccess Мultiplexer it cоntains ME, SE and AE, and TE functions are performed by Аccess Мultiplexer.
