48 OverviewHost interface busCards based on the IPE bus use a built-in microcontroller. The IPEmicrocontroller is used for the following:• to perform local diagnostics (self-test)• to configure the card according to instructions issued by the systemprocessor• to report back to the system processor information such as cardidentification (type, vintage, and serial number), firmware version, andprogrammed configuration status.Table 7Differences between IPE parametersParameter IPECard Dimensions 31.75 x 25.4 x 2.2 cm.

Figure 11 "Typical IPE trunkcard architecture" (page 49) shows a typical IPE trunk card architecture.The various trunk cards differ only in the number and types of trunk interfaceunits.Nortel Communication Server 1000Circuit Card ReferenceNN43001-311 01.04 StandardRelease 5.0 23 May 2008Copyright © 2003-2008, Nortel Networks.
