There are five serial channel physical interface combinations for the three SCCs (see Table
4-1).
The PCM highway interface is a flexible time-division multiplexed interface. It allows the
MC68302 to connect to popular time-slot interfaces such as T1 and CEPT as well as user-
defined time-slot interfaces.
The IDL and GCI (IOM-2) interfaces are used to connect to semiconductor devices that sup-
port the Integrated Services Digital Network (ISDN). IDL and GCI allow the MC68302 to
communicate over any of the 2B + D ISDN basic rate channels.
