Port Adapter Overview

The PA-4T+ provides the following electrical interfaces: EIA/TIA-232, EIA/TIA-449, EIA-530. X.21, and V.35.Each interface complies with itsspeciﬁcinterface speciﬁcations. The cable attached to each PA-4T+ port adapter’s interface ports determines its type (EIA/TIA-232, and so forth) and its mode (data communications equipment [DCE] or data terminal equipment [DTE]).

Note The PA-4T+ provides enhanced performance over the PA-4T. To determine if a PA-4T+ or

PA-4T is installed in your router, view the port adapters’ faceplate labels (refer to Figure 1-1 and Figure 1-2, respectively) or use the show diag command to view installed interface types.

Synchronous Serial Overview

The PA-4T+ 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.

EIA/TIA-232, which is by far the most common interface standard in the U.S.,supportsunbalanced circuits at signal speeds up to 64 kbps. EIA/TIA-449, which supports balanced (EIA/TIA-422) and unbalanced (EIA/TIA-423) transmissions, is a faster (up to 2 Mbps) version of EIA/TIA-232 that provides more functions and supports transmissions over greater distances. The EIA/TIA-449 standard was intended to replace EIA/TIA-232, but it was not widely adopted.

Note The EIA/TIA standards were referred to as recommended standards called RS-232 and

RS-449 prior to their acceptance by the ANSI committee.

The resistance to convert to EIA/TIA-449 was due primarily to the large installed base of DB-25 hardware and to the larger size of the 37-pin EIA/TIA-449 connectors, which limited the number of connections possible (fewer than is possible with the smaller, 25-pin EIA/TIA-232 connector).

EIA-530, which supports balanced transmission, provides the increased functionality, speed, and distance of EIA/TIA-449 on the smaller, DB-25 connector used for EIA/TIA-232. The EIA-530 standard was created to support the more sophisticated circuitry of EIA/TIA-449 on the large number ofexisting EIA/TIA-232 (DB-25) hardwareinstead of the larger,37-pin connectors usedfor

Overview 1-3

Serial Interface Specifications

EIA/TIA-449. Like EIA/TIA-449, EIA-530 refers to the electrical speciﬁcations of EIA/TIA-422 and EIA/TIA-423. The speciﬁcation recommends a maximum speed of 2 Mbps. EIA-530 is used primarily in the United States.

The V.35 interface is most commonly used in the United States and throughout Europe, and is recommended for speeds up to 48 kbps. The X.21 interface uses a 15-pin connection for balanced circuits and is commonly used in the United Kingdom to connect public data networks. X.21 relocates some of the logic functions to the data terminal equipment (DTE) and data communications equipment (DCE) interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232.

All interface types except EIA-530 can be individuallyconﬁguredforoperation with either external (DTE mode) or internal (DCEmode)timingsignals;EIA-530 operates with external timing only.In addition, all VIP2 serial interface types support nonreturn to zero (NRZ) and nonreturn to zero inverted (NRZI) format, and both 16-bit and 32-bit cyclic redundancy checks (CRCs). The default conﬁguration is for NRZ format and 16-bit CRC. You can change the default settings with software commands. (For more information, see the Chapter 8, “Conﬁguring the PA-4T+ Interfaces.”)

There is no default mode or clock rate set on the VIP2 serial ports, although an internal clock signal is presentonall ports for DCE support. Theinternalclock also allows you toperformlocal loopback tests without having to terminate the port or connect a cable. (All interface types except X.21 DTE support loopback.)Touse the port asa DCE interface,youmust set theclockrate and connectaDCE adapter cable. Touse the port as a DTE interface, you need only connect a DTE adapter cable to the port. Because the serial adapter cables determine the mode and interface type, the PA-4T+interface becomes a DTE when a DTE cable is connected to it.

If a DTE cable is connected to a port with a clock rate set, the DTE ignores the clock rate and uses the external clock signal that is sent from the remote DCE. For a brief description of the clockrate command,seeChapter 8,“Conﬁguring the PA-4T+Interfaces.”For completecommanddescriptions and instructions, see the publications listed in the section “Related Documentation” section on page vi.

Serial Interface 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 distancelimitsfor EIA/TIA-449 showninTable 1-1 are alsovalid 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.

Cables 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+ Receptacles and Cables

The PA-4T+and adapter cables allow a high density of interface ports, regardless of the size of the connectorstypicallyused witheachelectrical interfacetype.All portsusean identical60-pinD-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 adaptercable determines the electricalinterface type and modeof the port (DTEor DCE)

to which it is connected.

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 availableonly 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-232 Connections

The router end of all EIA/TIA-232 adapter cables is a high-density 60-pin plug. The 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.

Note 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 PA-4T+ 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 PA-4T+ receptacles.

Note Do not use the Cisco Systems-provided EIA/TIA-232 adapter cable CAB-232MT= to

connect a PA-4T+ interface that is conﬁgured for DTE mode directly to an NEC - NEXTSTAR 1E model C4969 MD/SACunitinterfacethat is conﬁgured for DCE mode. Doing so will keep transmit and receive data signals from being properly exchanged between the two interfaces.

Instead, you must connect an additional, intermediate adapter cable—with standard EIA/TIA-232 DB-25 connectors at both ends—from the network end of CAB-232MT= to the standard EIA/TIA-232 DB-25 connector (the DCE interface) on the NEC - NEXTSTAR 1E model C4969 MD/SAC unit. Cisco Systems does not provide this additional cable; however, its signals and pin assignments are listed in Table 1-3.

LEDs

The PA-4T+ contains the enabled LED, standard on all port adapters, and 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 1-9.)

Figure 1-9 LEDs on the PA-4T+—Horizontal Orientation

H4491

The following conditions must be met before the PA-4T+ is enabled:

• The port adapter is correctly connected to the backplane midplane and receiving power.

• A valid system software image for the port adapter has been downloaded successfully.

• The system software recognizes the port adapter or VIP2 with an installed PA-4T+.
