Overview  
This chapter describes the PA-4T port adapter and contains the following sections:  
Port Adapter Overview  
The PA-4T, shown in Figure 1-1, provides four channel-independent, synchronous serial ports that  
support full-duplex operation at T1 (1.544 Mbps) and E1 (2.048 Mbps) speeds. Each port supports any  
of the available interface types: Electronics Industries Association/Telecommunications Industries  
Association (EIA/TIA)-232, EIA/TIA-449, V.35, X.21, and EIA-530. The cable attached to each PA-4T  
interface port determines its type (EIA/TIA-232, and so forth) and its mode (DCE or DTE).  
Note  
Although the VIP supports online insertion and removal (OIR), individual port adapters do not. To  
replace port adapters, you must first remove the VIP from the chassis, and then replace port adapters as  
required.  
Cisco 7200 series routers support OIR of all port adapter types.

Chapter 1 Overview  
Synchronous Serial Specifications  
Synchronous Serial Specifications  
The PA-4T provides up to four synchronous serial interfaces. Each interface allows a maximum  
bandwidth of 2.048 Mbps; the speed depends on the type of electrical interface used. Use EIA/TIA-232  
for speeds of 64 kilobits per second (kbps) and below, and use X.21, EIA/TIA-449, V.35, or EIA-530 for  
higher speeds.  
Serial signals can travel a limited distance at any given bit rate; generally, the slower the baud rate, the  
greater the distance. All serial signals are subject to distance limits beyond which a signal degrades  
significantly or is completely lost.  
Table 1-1 lists the recommended (standard) maximum speeds and distances for each PA-4T serial  
interface type. The recommended maximum rate for V.35 is 2,048 Mbps.

Balanced drivers allow EIA/TIA-449 signals to travel greater distances than EIA/TIA-232. The  
recommended distance limits for EIA/TIA-449 shown in Table 1-1 are also valid for V.35, X.21, and  
EIA-530. EIA/TIA-449 and EIA-530 support 2.048-Mbps rates, and V.35 supports 2.048-Mbps rates  
without any problems; we do not recommend exceeding published specifications for transmission speed  
versus distance. Do so at your own risk.  
LEDs  
The PA-4T contains the enabled LED, standard on all port adapters, and a one status LED for each port.  
After system initialization, the enabled LED goes on to indicate that the PA-4T has been enabled for  
operation. The LEDs are shown in Figure 1-2.

Cables, Connectors, and Pinouts  
The green enabled LED on the port adapter indicates that the motherboard is enabled and receiving  
power, and that the port adapter is ready for operation.  
The following conditions must be met before the enabled LED goes on:  
The PA-4T interface is correctly connected and receiving power  
The PA-4T-equipped card or router contains a valid microcode version that has been downloaded  
successfully  
The bus recognizes the PA-4T or PA-4T-equipped VIP  
If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED does  
not go on.  
Table 1-2 lists LED colors and indications.

Cables, Connectors, and Pinouts  
The following sections describe the serial receptacles on the PA-4T, and the cables and pinouts for the  
various serial interface cables.  
PA-4T Port Adapter Receptacles and Cables  
The PA-4T and adapter cables allow a high density of interface ports, regardless of the size of the  
connectors typically used with each electrical interface type. All ports use an identical 60-pin, D-shell  
receptacle that supports all interface types: EIA/TIA-232, V.35, EIA/TIA-449, X.21, and EIA-530. Each  
port requires a serial adapter cable, which provides the interface between the high-density serial port and  
the standard connectors that are commonly used for each electrical interface type.  
Note  
The adapter cable determines the electrical interface type and mode of the port (DTE or DCE) to which  
it is connected.

Chapter 1 Overview  
Cables, Connectors, and Pinouts  
The network end of the cable is an industry-standard connector for the type of electrical interface that  
the cable supports. For most interface types, the adapter cable for DTE mode uses a plug at the network  
end, and the cable for DCE mode uses a receptacle at the network end. Exceptions are V.35 adapter  
cables, which are available with either a V.35 plug or a receptacle for either mode, and the EIA-530  
adapter cable, which is available only in DTE mode with a DB-25 plug at the network end. The mode is  
labeled on the molded plastic connector shell at the ends of all cables except V.35 (which uses the  
standard Winchester block-type connector instead of a molded plastic D-shell).  
Following are the available interface cable options (and product numbers) for the mode and network-end  
connectors for each cable:  
EIA/TIA-232: DTE mode with a DB-25 plug (CAB-232MT=); DCE mode with a DB-25 receptacle  
(CAB-232FC=)  
EIA/TIA-449: DTE mode with a 37-pin D-shell plug (CAB-449MT=); DCE mode with a 37-pin  
D-shell receptacle (CAB-449C=)  
V.35: DTE mode or DCE mode with a 34-pin Winchester-type V.35 plug (CAB-V35MT= or  
CAB-V35MC=); DTE mode or DCE mode with a 34-pin Winchester-type V.35 receptacle  
(CAB-V35FT= or CAB-V35FC=). Also available is a cable with a male DB-60 plug on the router  
end and a male DB-34 shielded plug on the network end (CAB-V35MTS=).  
X.21: DTE mode with a DB-15 plug (CAB-X21MT=); DCE mode with a DB-25 receptacle  
(CAB-X21FC=)  
EIA-530: DTE mode with a DB-25 plug (CAB-530MT=)

Metric (M3) thumbscrews are included with each port adapter cable to allow connections to devices that  
use metric hardware. Because the 4T port adapter uses a special, high-density port that requires special  
adapter cables for each electrical interface type, we recommend that you obtain serial interface cables  
from the factory.  
EIA/TIA-232 Connections  
The router (VIP) end of all EIA/TIA-232 adapter cables is a high-density 60-pin plug. The opposite  
(network) end of the adapter cable is a standard 25-pin D-shell connector (known as a DB-25) that is  
commonly used for EIA/TIA-232 connections. Figure 1-4 shows the connectors at the network end of  
the adapter cable. The system console and auxiliary ports on the Route Switch Processor (RSP) in the  
Cisco 7500 series also use EIA/TIA-232 connections; however, the 4T port adapter interfaces support  
synchronous serial connections, and the console and auxiliary ports only support asynchronous  
connections. Use caution when connecting EIA/TIA-232 cables to the 4T receptacles.

4T Port Adapter Cable Pinouts  
The 4T port adapter supports EIA/TIA-232, EIA/TIA-449, X.21, V.35, and EIA-530 serial interfaces.  
All 4T ports use a a 60-pin receptacle that supports all available interface types. A special serial adapter  
cable, which is required for each port, determines the electrical interface type and mode of the interface.  
The router (VIP) end of all of the adapter cables is a 60-pin plug; the connectors at the network end are  
the standard connectors used for the respective interfaces.  
All interface types except EIA-530 are available in DTE or DCE format: DTE with a plug connector at  
the network end and DCE with a receptacle at the network end. V.35 is available in either mode with  
either gender at the network end. EIA-530 is available in DTE only.  
The tables that follow list the signal pinouts for both the DTE and DCE mode serial port adapter cables,  
for each of the following 4T port adapter interface types:

Port Adapter Slot Locations on the Supported Platforms  
This section discusses port adapter slot locations on the supported platforms. The illustrations that  
follow summarize slot location conventions on each platform.  
Cisco 7200 Series Router Slot Numbering  
Figure 1-9 shows a Cisco 7206 with port adapters installed. In the Cisco 7206, port adapter slot 1 is in  
the lower left position, and port adapter slot 6 is in the upper right position. (The Cisco 7202 and Cisco  
7204 are not shown; however, the PA-4T can be installed in any available port adapter slot.)

Identifying Interface Addresses  
This section describes how to identify interface addresses for the PA-4T in supported platforms.  
Interface addresses specify the actual physical location of each interface on a router or switch.  
Interfaces on the PA-4T installed in a router maintain the same address regardless of whether other port  
adapters are installed or removed. However, when you move a port adapter to a different slot, the first  
number in the interface address changes to reflect the new port adapter slot number.  
Interfaces on a PA-4T installed in a VIP maintain the same address regardless of whether other interface  
processors are installed or removed. However, when you move a VIP to a different slot, the interface  
processor slot number changes to reflect the new interface processor slot.  
Note  
Interface ports are numbered from left to right starting with 0.  
Table 1-8 explains how to identify interface addresses.

Chapter 1 Overview  
Identifying Interface Addresses  
Cisco 7200 Series Routers Interface Addresses  
This section describes how to identify the interface addresses used for the PA-4T in Cisco 7200 series  
routers. The interface address is composed of a two-part number in the format  
port-adapter-slot-number/interface-port-number. See Table 1-8 for the interface address format.  
In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right,  
beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4  
for the Cisco 7204, and slot 6 for the Cisco 7206. (Port adapter slot 0 is reserved for the optional Fast  
Ethernet port on the I/O controller—if present.)  
The interface addresses of the interfaces on the PA-4T in port adapter slot 1 are  
1/0 through 1/7 (port adapter slot 1 and interfaces 0 through 7). If the PA-4T was in port adapter slot 4,  
these same interfaces would be numbered 4/0 through 4/7 (port adapter slot 4 and interfaces  
0 through 3).  
VIP Interface Addresses  
This section describes how to identify the interface addresses used for the PA-4T on a VIP in Cisco 7500  
series routers.  
Note  
Although the processor slots in the 7-slot Cisco 7507, the 13-slot, and the 13-slot Cisco 7576 are  
vertically oriented and those in the 5-slot Cisco 7505 are horizontally oriented, all Cisco 7500 series  
routers use the same method for slot and port numbering.  
See Table 1-8 for the interface address format. The interface address is composed of a three-part number  
in the format interface-processor-slot-number/port-adapter-slot-number/interface-port-number.  
If the VIP is inserted in interface processor slot 3, then the interface addresses of the PA-4T are 3/1/0  
through 3/1/3 (interface processor slot 3, port adapter slot 1, and interfaces 0 through 3). If the  
port adapter was in port adapter slot 0 on the VIP, these same interface addresses would be numbered  
3/0/0 through 3/0/3.  
Note  
If you remove the VIP with the PA-4T (shown in Figure 1-11) from interface processor  
slot 3 and install it in interface processor slot 2, the interface addresses become 2/1/0 through 2/1/3.
