3.2 Installing hardware
Permitted number of communications processors in the PG/PC
The driver software supports a maximum of 2 communications processors per PG/PC, of
which a maximum of 1 communications processor may be in configured mode.
Automatic adaptation of the bus clock speed
The communications processor is designed for a bus clock speed of 66 MHz. If the
communications processor is inserted in a PCI slot with a higher bus clock speed, the bus
clock speed is adapted to the highest possible bus rate of the communications processor.
Examples:
• The PCI slot is automatically reduced to a bus clock speed of 66 MHz.
• The bus clock speed of the communications processor is automatically reduced to 33 MHz
if a communications processor with a 33 MHz bus clock speed is connected.
