You can identify a rollover cable by comparing the modular plugs at the two ends of the cable. When you hold the plugs side by side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See Figure 2.) If you purchased your cable from Cisco Systems, pin 1 is white on one connector, and pin 8 is white on the other (a rollover cable connects pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).

Token Ring Port Pinouts
The 1E1R 2-slot module provides both UTP and STP Token Ring connections described in these sections:
•Token Ring STP Connector Pinouts
•Token Ring UTP Connector Pinouts
The IEEE has established Token Ring as standard IEEE 802.5. The distance limitations for the IEEE 802.5 specification indicate a maximum segment distance of 328 feet (100 meters) for UTP cabling. The distance limitation is 1,640 feet (500 meters) for STP cabling.
Note To ensure agency compliance with FCC Class B electromagnetic emissions requirements (EMI), make sure that you use the shielded RJ-45 Token Ring cable when connecting your router to the Token Ring network.
Token Ring can operate at two different ring speeds: 4 and 16 Mbps. All devices on the ring must use the same operating speed.
Only one Token Ring port can be used at a time. The module will automatically detect which port, STP or UTP, is in use. Use the provided Token Ring cable to connect the router to a switch.
Token Ring STP Connector Pinouts
Table 7 shows the Token Ring STP port pinouts used by the 1E1R 2-slot module.

ISDN BRI Interface
This section contains the following topics:
•ISDN BRI Connections
•ISDN BRI Pinouts
Warning Network hazardous voltages are present in the BRI, fractional T1/T1, and switched 56 cables. If you detach the cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the BRI port (RJ-45 connector), fractional T1/T1 port (RJ-48C connector), and switched port (RJ-11 or RJ-48S connector), regardless of when power is turned OFF. Statement 59
ISDN BRI Connections
Warning The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers. Statement 23
Use a BRI cable (not included) to connect BRI ports on WAN interface cards (WICs) or on high speed WICs (HWICs) directly to an ISDN. Table 9 lists the specifications for ISDN BRI cables.

CT1/PRI Pinouts
Two standard T1 serial cables are available for the CT1/PRI module: null modem and straight-through. A straight-through cable connects the router to an external CSU. Null modem cables are used for back-to-back operation and testing.
The T1 interface cable has two 15-pin DB connectors at each end to connect the CT1/PRI module with the external T1 CSU. Figure 6 shows the T1 interface cable, connectors, and pinouts. Table 12 lists the pinouts for the null modem T1 cable, and Table 13 lists the pinouts for the straight-through T1 cable.
Warning Network hazardous voltages are present in the BRI, fractional T1/T1, and switched 56 cables. If you detach the cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the BRI port (RJ-45 connector), fractional T1/T1 port (RJ-48C connector), and switched port (RJ-11 or RJ-48S connector), regardless of when power is turned OFF.

56/64-kbps DSU/CSU Signals and Pinouts
Switched 56-kbps connections are provided by the 56-kbps DSU/CSU WAN interface card (WIC). For more information, see the Network Modules Hardware Installation Guide.
Warning Network hazardous voltages are present in the BRI, fractional T1/T1, and switched 56 cables. If you detach the cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are present on the system card in the area of the BRI port (RJ-45 connector), fractional T1/T1 port (RJ-48C connector), and switched port (RJ-11 or RJ-48S connector), regardless of when power is turned OFF. Statement 59
Table 16 lists the 56/64-kbps DSU/CSU connector signals and pinouts.

Serial Connection Signals and Pinouts
This section provides information about the 1-port serial WAN interface card (WIC). With the appropriate serial transition cable, this WIC can provide an EIA/TIA-232, EIA/TIA-449, V.35, X.21, DTE/DCE, EIA-530 DTE, or NRZ/NRZI serial interface.
Types of Serial Cables
Five types of serial cables (also called serial adapter cables or serial transition cables) are available from Cisco Systems:
•EIA/TIA-232 Interface
•EIA/TIA-449 Interface
•V.35 Interface
•X.21 Serial Cable Assembly
•EIA-530 Interface
All serial cables provide a universal plug at the WIC end. The network end of each cable provides the physical connectors most commonly used for the interface. For example, the network end of the EIA/TIA-232 serial cable is a DB-25 connector, the most widely used EIA/TIA-232 connector.
All serial interface types except EIA-530 are available in DTE or DCE format: DTE with a plug connector (male) at the network end and DCE with a receptacle (female) 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.
Connecting the WIC to the Network
Note The serial WIC uses a universal high-density, 60-pin receptacle. Each universal port requires a serial port adapter cable that determines the port's electrical interface type and mode: DTE or DCE. Although all port adapter cables use a universal plug at the serial module end, the network end of each cable type uses the physical connectors commonly used for the interface. (For example, the network end of the EIA/TIA-232 port adapter cable is a DB-25 connector, the most widely used EIA/TIA-232 connector.)
After you install the serial WIC, use the appropriate serial cable to connect the WIC DB-60 serial port to one of the following types of equipment:
•An asynchronous modem, if connecting to an analog telephone line
•A synchronous modem, data service unit/channel service unit (DSU/CSU), or other data circuit-terminating equipment (DCE), if connecting to a digital WAN line
EIA/TIA-232 Interface
This section contains the following topics:
•EIA/TIA-232 Connections
•EIA/TIA-232 Serial Cable Assembly
EIA/TIA-232 Connections
EIA/TIA-232 supports unbalanced circuits at signal speeds up to 64 kbps. The network end of the adapter cable is a standard 25-pin D-shell connector known as a DB-25. (See Figure 13.) The router console and auxiliary ports also use EIA/TIA-232 connections; however, the serial module ports support synchronous connections, and the console and auxiliary ports support asynchronous connections.
Figure 13 EIA/TIA-232 Adapter Cable Connectors, Network End
EIA/TIA-232 Serial Cable Assembly
Figure 14 shows the EIA/TIA-232 serial cable assembly. Table 19 lists the DTE pinout and Table 20 lists the DCE pinout. Arrows indicate signal direction: —> means DTE to DCE and <— means DCE to DTE.

EIA/TIA-449 Interface
This section contains the following topics:
•EIA/TIA-449 Connections
•EIA/TIA-449 Serial Cable Assembly
EIA/TIA-449 Connections
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 the EIA/TIA-232 standard, but it was not widely adopted primarily because of the large installed base of DB-25 hardware and because of the larger size of the 37-pin EIA/TIA-449 connectors, which limited the number of connections possible (fewer than possible with the smaller, 25-pin EIA/TIA-232 connector).
The network end of the EIA/TIA-449 adapter cable provides a standard 37-pin D-shell connector. (See Figure 15.) EIA/TIA-449 cables are available as either DTE (DB-37 plug) or DCE (DB-37 receptacle).

V.35 Interface
This section contains the following topics:
•V.35 Connections
•V.35 Serial Cable Assembly
V.35 Connections
The V.35 interface is recommended for speeds up to 48 kbps, although in practice it is used successfully at 4 Mbps.
The network end of the V.35 adapter cable provides a standard 34-pin Winchester-type connector. (See Figure 17.) V.35 cables are available with a standard V.35 plug or receptacle in either DTE or DCE mode.
Figure 17 V.35 Adapter Cable Connectors, Network End
V.35 Serial Cable Assembly
Figure 18 shows the V.35 serial cable assembly. Table 23 lists the DTE pinout and Table 24 lists the DCE pinout. Arrows indicate signal direction: —> means DTE to DCE and <— means DCE to DTE.

X.21 Interface
This section contains the following topics:
•X.21 Connections
•X.21 Serial Cable Assembly
X.21 Connections
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 DTE and DCE interfaces and, as a result, requires fewer circuits and a smaller connector than EIA/TIA-232.
The network end of the X.21 adapter cable is a standard DB-15 connector. (See Figure 19.) X.21 cables are available as either DTE (DB-15 plug) or DCE (DB-15 receptacle).
Figure 19 X.21 Adapter Cable Connectors, Network End
X.21 Serial Cable Assembly
Figure 20 shows the X.21 serial cable assembly. Table 25 lists the DTE pinout, and Table 26 lists the DCE pinout. Arrows indicate signal direction: —> means DTE to DCE and <— means DCE to DTE.

EIA-530 Interface
This section contains the following topics:
•EIA-530 Connections
•EIA-530 Serial Cable Assembly
EIA-530 Connections
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, instead of the 37-pin connectors used for EIA/TIA-449. Like EIA/TIA-449, EIA-530 refers to the electrical specifications of EIA/TIA-422 and EIA/TIA-423. Although the specification recommends a maximum speed of 2 Mbps, EIA-530 is used successfully at 4 Mbps or faster speeds over short distances.
The EIA-530 adapter cable is available in DTE mode only. The network end of the EIA-530 adapter cable is a standard DB-25 plug commonly used for EIA/TIA-232 connections. Figure 21 shows the DB-25 connector at the network end of the adapter cable.
Figure 21 EIA-530 Adapter Cable Connector, Network End
EIA-530 Serial Cable Assembly
Figure 22 shows the EIA-530 serial cable assembly, and Table 27 lists the pinout. Arrows indicate signal direction: —> means DTE to DCE and <— means DCE to DTE.
The EIA-530 interface cannot be operated in DCE mode, and no DCE cable is available for it.

Smart Serial Connection Signals and Pinouts
The Smart Serial cable interface supports multiple independent serial interface ports. Each port supports five types of serial interfaces:
•EIA/TIA-232 Smart Serial Cable Assembly
•EIA/TIA-449 Smart Serial Cable Assembly
•X.21 Smart Serial Cable Assembly
•V.35 Smart Serial Cable Assembly
•EIA-530 Smart Serial Cable Assembly
The serial end (router end) of the Smart Serial cable is a 26-pin connector.
These cables are used with the following interface cards:
•2-port serial and 2-port asynchronous or synchronous WICs
•4-port serial and 4-port asynchronous or synchronous high-speed WICs (HWICs)
Figure 23 shows the serial cables you can connect to the port on the asynchronous or synchronous serial modules and the serial WICs and HWICs.
Figure 23 Smart Serial Interface Cables

Octopus Cable Connection Signals and Pinouts
This section contains the following topics:
•4-Port RS-232 Cable Assembly
•8-Port RS-232 Cable Assembly
4-Port RS-232 Cable Assembly
The 4-port RS-232 cable was designed for use with the Cisco 8-port RS-232 asynchronous or synchronous high-speed WAN interface card (HWIC) (the Cisco HWIC-8A-RS232). The router end of the cable consists of a 68-pin 2-row D-shell connector. The network end of the cable consists of 4 standard 25-pin D-shell connectors (DB-25 connectors). These cables are available in either DTE or DCE format. See Figure 24.
Figure 24 4-Port RS-232 Cable Connectors, Network End
Figure 25 shows the 4-port RS-232 cable assembly. Table 38 lists the cable's DTE pinout, and Table 39 lists the cable's DCE pinout. Arrows indicate signal direction: —> means DTE to DCE and <— means DCE to DTE.

8-Port RS-232 Cable Assembly
The 8-port RS-232 cable was designed for use with the Cisco 8-port and 16-port RS-232 asynchronous HWICs (the Cisco HWIC-8A and Cisco HWIC-16A). The router end of the cable consists of a standard 68-pin 2-row D-shell connector. The network end of the cable provides eight standard 8-pin RJ-45 connectors. These cables are available in DTE format only. See Figure 26.
Figure 26 8-Port RS-232 Cable Connector, Network End
Figure 27 shows the 8-port RS-232 cable assembly. Table 40 lists the DTE pinout for the 8-port RS-232 cable. Arrows indicate signal direction: —> means DTE to DCE and <— means DCE to DTE.
