The channel structure of the IOM-2 is described in figure 29.
Figure 29
Channel Structure of IOM
In case of an IOM-2 interface the frame structure depends on whether TE- or
non-TE-mode is selected.
Non-TE-Timing Mode
The frame of this mode is a multiplex of eight IOM-2 channels (figure 30), each channel
has the structure as shown in figure 29.
The ARCOFI is assigned to one of eight channels (0 to 7) by strapping SB to SD
according to the following table:

Pin SA is not used in this mode and should be connected to
Thus the data rate per channel is 256 kbit/s, whereas the bit rate is 2.048 kbit/s. The
IOM-2 interface signals are:
DD, DU : 2048 kbit/s

Semiconductor Group
The 64-kbit/s channels, B1 and B2, are conveyed in the first two bytes.
The third byte (monitor channel) is used for programming and controlling devices
attached to the IOM-2 interface.
The fourth byte (control channel) contains two bits for the 16-kbit/s D-channel, four
command/indication bits for controlling activation/deactivation and for additional
control functions, two bits MR and MX for supporting the handling of the MONITOR
channel.
