IOM-2 is a standardized interface for interchip communication in ISDN line cards for
digital exchange systems developed by ALCATEL, Siemens, Plessey and ITALTEL.
The IOM-2 interface is a four-wire interface with a bit clock, a frame clock and one data
line per direction. It has a flexible data clock. This way, data transmission requirements
are optimized for different applications.
