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 octet 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.
