IOM-2 defines an industry-standard serial bus for interconnecting telecommunication
ICs for a broad range of applications - typically ISDN-based applications.
The IOM-2 bus provides a symmetrical full-duplex communication link containing data,
control/programming and status channels. Providing data, control and status information
via a serial channel reduces pin count and cost by simplifying the line card layout.
The IOM-2 Interface consists of two data lines and two clock lines as follows:
