Note that the CM of the ELIC is not reset with a physical ELIC reset. Thus, the first step
in initializing the CM is to set all addresses to ‘unassigned channel’. Next, the monitor
and control time slot pairs are programmed for both IOM-2 channels. For a detailed
6.1.3
This part of the Application Note completes the initialization of the ELIC, and thus of the
line card, by setting the Control Memory (CM) of the ELIC to handle the monitor and
control time slots of two digital IOM-2 subscribers. As shown below, the OCTAT-P is set
into the deactivated (idle) state:

Idle State of Line Card with ELIC
description of CM handling please refer to chapter 5.3 of the Application Hints. With the
CM initialized, the CFI and PCM interfaces can be activated. Finally, the OCTAT-P is set
into the deactivated (idle) state by the appropriate C/I code.
