Prerequisites for Connecting 1- and 2-Port Serial HWICs to a Network
Before connecting an HWIC to the network, ensure that the HWIC is installed in the router, that the 
equipment is properly grounded, and that you have the proper cables for connecting the HWIC to the 
network. This section describes the preparation necessary before connecting a 1- or 2-Port HWIC to the 
network.
Installing a Cisco Serial WAN Interface Card
Install the Cisco serial WAN interface card according to the instructions in 
Grounding
Ensure that the equipment you are working with is properly grounded according to the instructions in 
Cables
After you install the serial HWIC, use the appropriate serial cable to connect the HWIC’s serial port to 
one of the following types of equipment:
An asynchronous modem, if connecting to an analog telephone line
A synchronous modem, DSU or CSU, or other DCE, if connecting to a digital WAN line
The 1-port serial HWIC, the 2-port serial HWIC, and the 2-port A/S HWIC have Cisco smart serial ports. 
Use the correct cable for your serial HWIC.
The serial cable attached to a smart serial port determines the port’s electrical interface type and mode 
(DTE or DCE).
Types of Cables for 1- and 2-Port Serial HWICs
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 HWICs:
EIA/TIA-232 serial cable assembly
EIA/TIA-449 serial cable assembly
V.35 serial cable assembly
X.21 serial cable assembly
