Hardware Overview
2 Interphase Corporation
The modular adapter architecture includes a CPU motherboard
and a WAN daughtercard.
The CPU motherboard is powered by an IBM PowerPC
TM
403GA 32-bit RISC processor, combined with a 32-bit/33-
MHz PCI interface. The processor allows full support of
communication protocols, reducing host CPU usage.
The WAN daughtercard handles various communication
protocols at up to 2 megabits per second (Mbps). The
daughtercard supports the following serial interface types with
automatic recognition:
• V.24/V.28
• V.35
• X.21/V.11
NOTE
The iSPAN-Serial WAN adapter is referred to internally as
the 5535-1P-SR adapter. You might see both names used
in the Users Guide and the software dialog boxes to refer
to the adapter.
