10.1.5 Monitor Channel Data Structure
The monitor channel is used for the transfer of maintenance information between two
functional blocks. By use of two monitor control bits (MR and MX) per direction, the data
are transferred in a complete handshake procedure.
Address Byte
Messages to and from the SICOFI-4 are started with the following Monitor byte:
Bit
Thus providing information for two voice channels, the SICOFI-4 is one device on one
IOM-2 timeslot. Monitor data for a specific voice channel is selected by the SICOFI-4
specific command (SOP or COP).
Identification Command
In order to be able to unambiguously identify different devices by software, a two byte
identification command is defined for analog lines IOM-2 devices.
Each device will then respond with its specific identification code. For the SICOFI-4 this
two byte identification code is:
Each byte is transferred at least twice (in two consecutive frames).
