Port Adapter Overview

The PA-E3 is a single-width, one-port or two-port module that integrates data service unit (DSU)

functionality into the Cisco router (see Figure 1-1 and Figure 1-2). The module provides one or two

high-speed serial E3 interfaces on:

• Cisco 7100 series routers

• Cisco 7200 series routers

• Cisco uBR7200 series routers

• Second-generation Versatile Interface Processors (VIP2) in all Cisco 7000 series and Cisco 7500

series routers

• Catalyst RSM/VIP2 in the Catalyst 5000 family switches

Note Port adapters have a handle attached, but this handle is occasionally not shown in ﬁgures in

this publication to allow a full view of detail on the port adapter’s faceplate.
