One task of the IOM handler is to establish a communication path from DSP to the line
interface and vice versa.
Beside that function, it handles also the data transfer between line transveiver, HDLC
controller and TIC/CI channel handler. Additionally, it provides CPU access to all IOM-2
timeslots via the four controller data access (CDA) register and the IOM-2 Data Transfer
Unit.
The PCM data of the controller data access (CDA) registers and the IOM-2 Data
Transfer Unit can be configured by programming the corresponding time slot and data
port selection registers.
The IOM-2 handler provides access to the following blocks:
• DSP
• Transceiver
• C/I channel handler (C/I0,C/I1)
• TIC bus handler and
• HDLC controller
The following Figure 17-1 shows the architecture of the IOM-2 handler.
