Hardware Overview

The modular adapter architecture includes a CPU motherboard and a WAN daughtercard.

The CPU motherboard is powered by an IBM PowerPCTM 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-SRadapter. You might see both names used in the Users Guide and the software dialog boxes to refer to the adapter.

Hardware Overview

Following are the standard hardware features of the adapter:
