Overview
This chapter describes the one-port PA-T3 and two-port PA-2T3 serial port adapters. This chapter
contains the following sections:
•Port Adapter Overview, page 1-1
•PA-T3 Serial Port Adapter Features, page 1-2
•Management Information Base, page 1-3
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.)
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.

Figure 1-2 Two-Port PA-2T3 Serial Port Adapter
The PA-T3 serial port adapter can be installed in the following slots on the hardware platforms
described in this document:
•VIP2—Port adapter slot 0 and port adapter slot 1
•Catalyst RSM/VIP2—Port adapter slot 0 and port adapter slot 1
•Cisco 7100 series routers—Port adapter slot 3 in the Cisco 7120 series and port adapter slot 4 in
the Cisco 7140 series
•Cisco 7200 series routers—Port adapter slot 1 and slot 2 of the Cisco 7202; port adapter slot 1
through slot 4 of the Cisco 7204 and Cisco 7204VXR; port adapter slot 1 through slot 6 of the
Cisco 7206 and Cisco 7206VXR
•Cisco uBR7200series routers—Port adapterslot 1 and slot 2of the Cisco uBR7246;port adapter
slot 1 of the Cisco uBR7223
The one-port PA-T3 serial port adapter provides two network interfaces per VIP2 for Cisco 7000
series and Cisco 7500 series routers, two network interfaces per Catalyst RSM/VIP2, and one
high-speed interface on the Cisco 7200 series and Cisco uBR7200 series routers. The two-port
PA-2T3 serial port adapter provides four network interfaces per VIP2 for Cisco 7000 series and
Cisco 7500 series routers, four network interfaces for the Catalyst RSM/VIP2, and two high-speed
interfaces on the Cisco 7200 series and Cisco uBR7200 series routers. Serial network interfaces
reside on modular port adapters, which provide a direct connection between the high-speed bus in
the router and the external networks. The PA-T3 serial port adapter provides a full-duplex
synchronous serial PA-T3 interface for transmitting and receiving data at rates of up to 34 megabits
per second (Mbps).
The port adapter supports both 16- and 32-bit cyclic redundancy checks (CRCs). The default is
16-bitCRCs; to enable32-bit CRCs,you use aconfiguration command.Foradescription ofthe CRC
function, see the “Configuring Cyclic Redundancy Checks” section on page 8-13.
The VIP2 and Catalyst RSM/VIP2 support online insertion and removal (OIR), but individual port
adapters with a VIP2 or Catalyst RSM/VIP2 do not support OIR. To replace port adapters in the
Cisco7000 series andCisco 7500 seriesrouters, and theCatalyst 5000 series switches,you mustfirst
remove the VIP2 or Catalyst RSM/VIP2 from the chassis and then replace port adapters as required.
OIR is supported for port adapters in the Cisco 7200 series and Cisco uBR7200 series routers.
PA-T3 Serial Port Adapter Features
The PA-T3 serial port adapter provides the following features:
•Single-width port adapter for the VIP2 in all Cisco 7000 series, Cisco 7100 series, Cisco 7500
series, and Cisco 7200 series routers

(SNMP).
The one-port PA-T3 serial port adapter supports MIB-II (RFC 1213) and the DS3 interface MIB
(RFC 1407).
The two-port PA-2T3 serial port adapter supports MIB-II (RFC 1213) and the DS3 interface MIB
