This chapter provides information on various cables and transceivers. The information is organized into the following sections:
If a product number in this chapter ends with an equal sign (=), the item can be ordered only as a spare. If a product number does not end with an equal sign, the item can be ordered as a spare or as a configurable part of a system order. For example, a serial cable ordered as part of an original order uses part number CAB-232FC. The same cable ordered as a spare uses part number CAB232FC=.

One of the most complicated parts of setting up a router is the selection of the serial cables to connect the router to the serial devices in your network. There are many different serial cables with seemingly similar features, and finding the correct cable can be a challenge. The information that follows will quickly and easily guide you through the process of selecting the right serial cables for your network.
Selecting the proper serial cable is as easy as knowing the answers to three questions:
With the answers to these questions, and the model of your router, you can read the part number of the cable required from Table 330.
Devices that communicate over a serial interface are divided into two modes: data terminal equipment (DTE) and data communications equipment (DCE). The most important difference between these types of devices is that the DCE device supplies the clock signal that paces the communications on the bus. The documentation that came with the device should indicate whether it is DTE or DCE (some devices have a jumper to select either mode). If you cannot find the information in the documentation, use Table 329 to help you select the proper class.

If pins protrude from the base of the connector, the plug is male. If the connector has holes to accept the pins, the receptacle is female. Refer to Figure 157 to identify the connector you need.
A number of different standards define the signaling over a serial cable (including EIA/TIA-232, X.21, V.35, EIA/TIA-449, EIA-530, and EIA613 HSSI). Each standard defines the signals on the cable and specifies the connector at the end of the cable. The documentation for the device being connected should indicate the signaling standard used for that device. If you cannot find the information in the documentation, use the illustrations inside to select the signaling standard required. Select the connector in Figure 157 that will mate with the connector on your device, not the illustration that looks like the connector on the device.

Cisco does not provide these cables; they are widely available from other sources.
Figure 158 : RJ-45 Cable
To identify RJ-45 cable type, hold the two ends of the cable next to each other so that you can see the colored wires inside the ends, as shown in Figure 159.
Figure 159 : RJ-45 Cable Identification
Examine the sequence of colored wires to determine the type of RJ-45 cable, as follows:

This section describes the cables used with the Cisco LightStream 2020.
For Cisco LightStream 2020 cable product numbers, refer to Table 239 and Table 241 in the "Cisco LightStream 2020" chapter. For detailed cabling information, refer to the chapter "Cables and Connectors" in the LightStream 2020 Site Planning and Cabling Guide.

RS-449 Interface Straight-Through Cable
The RS-449 straight-through cable is used to connect an RS-449 fantail to an external RS-449 DCE device.
RS-449 Interface Crossover Cable
The RS-449 interface crossover cable is used to connect two LightStream 2020 switches via their RS-449 fantail interfaces, or to connect an RS-449 fantail to an external RS-449 DTE device.
V.35 Interface Straight-Through Cable
The V.35 interface straight-though cable is used to connect a V.35 fantail to an external V.35 DCE device.

The V.35 interface crossover cable is used to connect two LightStream 2020 switches via their V.35 fantail interfaces, or to connect a V.35 fantail to an external V.35 DTE device.
The 75-ohm coaxial data cable is used for making connections directly to the BNC connectors on the medium-speed access card (MSAC). In addition, this cable can be used as a means of external connection to or from the BNC connector on the T3/E3 fantail.
T3/E3 Fantail and Cable Harness
The T3/E3 fantail (dressing panel) contains 16 BNC connectors for external 75-ohm hookup, together with a cable harness that provides the means for direct connection between the back of the T3/E3 fantail and the SMB connectors on a T3AC or an E3AC access card. The T3/E3 fantail and cable harness are available separately.
To interconnect patch panels or T3/E3 fantails to T3AC or E3AC access cards, both 4-port and 8-port coaxial cable harnesses are offered by Cisco Systems.
A 50-pin data cable is used as to connect the bulkhead connector on the E1 CEMAC card and the back of the E1 fantail.
Cisco ATM devices support the cable types listed in Table 334 and the cable connectors listed in Table 335. The ATM cables listed in Table 334 are industry standard unless otherwise specified.
