Figure 3
gives an example of an application of the SBC in an IOM (ISDN Oriented Modular)
architecture.
By separate implementation of OSI layer-1 and layer-2 functions, and through unified control
procedures, the architecture provides flexibility with respect to various transmission techniques.
The IOM devices are all low-power, high integration, single + 5 V supply CMOS devices. Through
mode switching, each device may be used in several applications: thus with one and the same
limited set of devices all ISDN basic access configurations are covered. Note that one of the
compatible layer-1 devices (SBC, IBC, IEC) requires direct microprocessor control. This is, of
course, due to the fact that the IOM interface provides all the necessary functions for layer-1/layer-
2 communication.
