Port Adapter Overview
The PA-T3 serial port adapter is a single-width, one-port or two-port module that integrates data
service unit (DSU) functionality into the Cisco router. It provides one or two high-speed serial
PA-T3 interfaces on Cisco 7100 series routers, Cisco 7200 series routers, Cisco uBR7200 series
routers, on the second-generation Versatile Interface Processor (VIP2) in all Cisco 7000 series and
Cisco 7500 series routers, and on the Catalyst RSM/VIP2 in the Catalyst 5000 series switches. (See
Figure 1-1 and Figure 1-2.)
