CHAPTER

Overview 1-1

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

Management Information Base

Management Information Base (MIB) attributes are readable and writable across the Integrated

Local Management Interface (ILMI) through use of the Simple Network Management Protocol

(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

(RFC 1407).
