Data Sheet
2.2.1
The frame structure on the IOM-2 data ports (DU,DD) in IOM-2 terminal mode is shown
in figure 11.
Figure 11
IOM -2 Frame Structure in Terminal Mode
The frame is composed of three channels
• Channel 0 contains 144-kbit/s of user and signaling data (2B + D), a MONITOR
• Channel 1 contains two 64-kbit/s intercommunication channels (IC) plus a MONITOR
• Channel 2 is used for the TlC-bus access. Additionally channel 2 supports further IC
Note: Each octett related to any integrated functional block can be programmed to any
programming channel (MON0) and a command/indication channel (CI0) for control
and programming of the layer-1 transceiver.
and command/indicate channel (MON1, CI1) to program or transfer data to other IOM-
2 devices.
and MON channels.
