Replacing PECs

The 2.5 BCM1000 comes equipped with two processor expansion cards (PEC IIIs) mounted on the media services card (MSC). These modules provide signal processing capabilities for such applications as voice mail and IP telephony applications. If you plan to run a lot of IP telephones, you may need to upgrade to four PEC IIIs.

The 2.0 version of the BCM1000 contains four PEC Is. If you want to start using IP telephony resources, you need to upgrade to PEC IIIs.

This chapter describes the processes for removing and replacing a PEC module.

Figure 128 provides an overview of the process for replacing the PEC.
