Operational Description  
In chapters 2 and 3 the pins and user’s interfaces of the IEC-Q are described in detail.  
Using this information, this chapter describes the interaction between these interfaces in  
detail. The approach used is to describe how IEC-Q features can be accessed using the  
different user interfaces, described in chapter 3.  
Most of the IEC-Q features can be accessed via IOM®-2 interface. In the microprocessor  
mode the processor interface provides almost unlimited access to the IOM®-2 channels  
in upstream and downstream directions, and consequently to most of the IEC-Q  
features. This µP access to the IOM®-2 interface is described in section 4.1.  
Access to the U-interface is the scope of section 4.2. A detailed description is given  
about the possibilities of (always indirect) access to each channel of the U-interface and  
the behavior of the IEC-Q in each mode (e.g. NT, LT, EOC Auto and Transparent  
modes).  
Sections 4.3 and 4.4 cover the whole issue of activation and deactivation procedures  
and control. Section 4.3 describes layer 1 activation and deactivation procedures of  
different configurations. Section 4.4 describes the activation and deactivation control of  
the different modes of the IEC-Q itself.  
Access to numerous maintenance features is discussed in sections 4.5 through 4.9. This  
includes monitoring transmission quality, features supporting test loop-backs defined by  
the national PTTs, power status monitoring features as well as chip internal testing  
features.  
Features of the power controller interface are described in section 4.10 which applies  
only in the stand-alone mode.  
Section 4.11 applies only to the microprocessor mode if used in the NT or the TE mode,  
and describes how to program and access the S/G and BAC bit features which can be  
used in applications like Wireless Local Loop and D-Channel arbitration.
