1.4 NetPerformer Architecture and <strong>ATM</strong><br />
The NetPerformer hardware has been modified to support <strong>ATM</strong> by changing the Signaling<br />
Engine processor to an equivalent processor with <strong>ATM</strong> capabilities. Older units capable of<br />
supporting <strong>ATM</strong> are identified by the A suffix in the model number: the SDM-9360A,<br />
SDM-9380A and SDM-9585A. Figure 1-10 illustrates some details of this architecture on<br />
the SDM-9360A.<br />

NOTE: On the SDM-9220/9230 platform the Signaling Engine runs on the same processor<br />
as the main application (single processor architecture), while on the<br />
SDM-9360, SDM-9380 and SDM-9585 the Signaling Engine runs on a different<br />
processor than the main application.<br />
