Chapter 3 Connecting Serial Interface Cards to a Network

Serial WAN Interface Cards (WICs)

Connecting 1- and 2-Port Serial WICs to a Network

The 1-port serial WIC has a DB-60 serial port, whereas the 2-port serial WIC and the 2-port A/S WIC

have Cisco smart serial ports. Use the correct cable for your serial WIC.

The serial cable attached to a smart serial port determines the port’s electrical interface type and mode

(DTE or DCE).

Tip A cable providing surge protection (CAB-SS-SURGE) is also available from Cisco Systems. See the

“Connecting the Serial WAN Interface Card to the Network” section on page 3-4 for instructions on

connecting the surge protector cable.

Types of Cables for 1- and 2-Port Serial WICs

Six types of serial cables (also called serial adapter cables or serial transition cables) are available from

Cisco Systems for 1- and 2-port serial WICs:

• EIA/TIA-232 serial cable assembly

• EIA/TIA-449 serial cable assembly

• V.35 serial cable assembly

• X.21 serial cable assembly

• EIA/TIA-530 serial cable assembly

• EIA/TIA-530A serial cable assembly

All serial cables provide a universal plug at the interface card 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 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.
