    Serial and asynchronous High-Speed WAN Interface Cards (HWICs) provide highly flexible connections for Cisco Integrated Services Routers. These HWICs help customers enable applications such as WAN access, legacy protocol transport, console server, and dial access server. You can mix and match HWICs to tailor cost-effective solutions for common networking problems such as remote network management, external dial-modem access, low-density WAN aggregation, legacy protocol transport, and high-port-density support.


    Serial High-Speed WAN Interface Cards
    This section describes serial HWICs and how to connect 1- and 2-port Cisco serial HWICs to a network. It contains the following sections:

    •1- and 2-Port Serial HWICs

    •2-Port Asynchronous/Synchronous Serial HWIC

    •Serial WAN Interface Card LEDs

    •Supported Platforms

    •Prerequisites for Connecting 1- and 2-Port Serial WICs to a Network

    •Connecting 1- and 2-Port Serial HWICs to a Network

    1- and 2-Port Serial HWICs
    The 1-port serial HWIC (HWIC-1T), shown in Figure 1, and the 2-port serial HWIC (HWIC-2T), shown in Figure 2, provide an EIA/TIA-232, EIA/TIA-449, V.35, X.21, data terminal equipment/data communications equipment (DTE/DCE) interface, EIA-530 DTE interface, or nonreturn to zero/nonreturn to zero inverted (NRZ/NRZI) serial interface to a Cisco modular router.

    The 2-port asynchronous/synchronous (A/S) HWIC (HWIC-2A/S), shown in Figure 3, provides an EIA/TIA-232, EIA/TIA-449, V.35, X.21, DTE/DCE, EIA-530, or EIA-530A serial interfaces to a Cisco modular router.

    Serial WAN Interface Card LEDs
    Each serial HWIC has one LED, labeled CONN for each port, which lights when the serial port is connected. When the port is in DTE mode, the CONN LED indicates that Data Send Ready (DSR), Data Carrier Detect (DCD), and Clear To Send (CTS) have been detected. When the port is in DCE mode, Data Terminal Ready (DTR) and Ready To Send (RTS) have been detected. Table 1 describes the functions of the LEDs.


    Table 1 Serial HWIC LEDs
    LED status Description
    Green
    Monitored port is active (has initialized without error).

    Yellow
    Monitored port is in loopback mode.

    Off
    Monitored port is not active (has failed to initialize).





    Supported Platforms
    The HWIC-1T, HWIC-2T, and HWIC-2A/S interface cards support the following Cisco integrated services routers (ISRs):

    •Cisco 1841 ISR

    •Cisco 2801 ISR

    •Cisco 2811 ISR

    •Cisco 2821 ISR

    Prerequisites for Connecting 1- and 2-Port Serial WICs to a Network
    Before connecting an HWIC to the network, ensure that the HWIC is installed in the router, the equipment is properly grounded, and you have the proper cables for connecting the HWIC to the network. This section describes the preparation necessary for connecting a 1- and 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 Installing Cisco Interface Cards in Cisco Access Routers.

    Grounding
    Ensure that the equipment you are working with is properly grounded according to the instructions in the Installing Cisco Interface Cards in Cisco Access Routers document.

    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 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

    •EIA/TIA-530 serial cable assembly

    •EIA/TIA-530A serial cable assembly

    All serial cables have a universal plug at the interface card end. The network end of each cable provides the physical connectors that are most commonly used for the interface. For example, the network end of the EIA/TIA-232 serial cable is a DB-25 connector, which is the most widely used EIA/TIA-232 connector.

    All serial cable assemblies 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. The V.35 serial cable assembly is available in either mode with either gender at the network end.

    Connecting 1- and 2-Port Serial HWICs to a Network
    To connect the serial card to the WAN, follow these steps:


    --------------------------------------------------------------------------------

    Step 1 Confirm that the router is turned off.



    --------------------------------------------------------------------------------

    Warning To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect the high-speed WAN interface cards only to intra-building or unexposed wiring or cable that is shielded and grounded at both ends. The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.


    --------------------------------------------------------------------------------

    Step 2 Connect the serial cable to the connector on the card faceplate. (See Figure 4.)

    Figure 4 Connecting the Serial WAN Interface




    1 Serial interface
    3 Male serial cable

    2 Female serial cable





    Step 3 Connect the female end of the serial cable to the male end of the other serial connector for back-to-back connectivity. (See Figure 4.)

    Step 4 Connect one end of the appropriate serial cable to the connector on the card faceplate.

    Step 5 Connect the other end of the cable to the DTE or DCE.

    Step 6 Turn on power to the router by pressing the power switch to the ON ( | ) position.

    Step 7 Check that the CONN LED goes on, which indicates that the serial port detects the WAN serial connection.
