QMC Supplement
Using on-chip time slot assigners, the S/T and U interfaces in IDL2 mode can match the
QMC bus structure—both interfaces can be connected to a 2.048-MHz IDL2 bus and route
the B1 channel, B2 channel and D channel to any time slot.
Figure C-1 shows the IDL2 bus congured to match the QMC protocol.
Figure C-1. IDL2 Bus Structure for a Connection to the QMC Bus
C.2 Control and Status Information
Using the SPI port, the QUICC32 and the ISDN interfaces exchange control and status
information via out-of-band signaling. Optionally, the MC145572s could use an 8-bit
parallel port for control and status transfer, allowing the U interfaces to be connected to the
processor bus.
Figure C-2 shows the connection between the QUICC32 and an S/T interface.
