2.3.1
The IOM-2 is a generalization and enhancement of the IOM-1. While the basic frame structure
is very similar, IOM-2 offers further capacity for the transfer of maintenance information. In
terminal applications, the IOM-2 constitutes a powerful backplane bus offering
intercommunication and sophisticated control capabilities for peripheral modules.
The channel structure of the IOM-2 is depicted in figure 10.

Channel Structure of IOM
– two bits for the 16-kbit/s D channel
– four command/indication bits for controlling activation/deactivation and for additional control
– two bits MR and MX for supporting the handling of the MONITOR channel.

The 64-kbit/s channels, B1 and B2, are conveyed in the first two octets.
The third octet (monitor channel) is used for transferring maintenance information between
the layer-1 functional blocks (SBCX, IECQ) and the layer-2 controller (see chapter 2.3.4).
The fourth octet (control channel) contains
