Introduction to Cisco Interface Cards

Cisco interface cards are classified according to the technologies they support. For example, WAN interface cards (WICs) support WAN technologies, such as Gigabit Ethernet, and voice interface cards (VICs) support voice technologies. Voice/WAN interface cards (VWICs) can support voice, data, and voice and data applications, depending on the capabilities of the router in which the VWIC is installed. High-speed WAN interface cards (HWIC) provide expanded LAN and WAN capabilities, such as Gigabit Ethernet and Ethernet switching.

---

Note HWICs are supported on Cisco 1800 series (modular), Cisco 2800 series, and Cisco 3800 series routers.

---

Cisco interface cards are available in the following two form factors to provide greater modularity and functionality for users:

•Single-wide interface cards (see Figure 1)

•Double-wide interface cards (see Figure 2)

Single-wide interface cards can be installed in interface card slots on supported Cisco access routers, in 1- or 2-slot network modules to be installed in network module slots on supported Cisco access routers, and in interface card slots on Cisco 1800 (modular) series, Cisco 2800 series, and Cisco 3800 series routers. See Figure 1 for a sample single-wide interface card.

Figure 1 Sample Single-Wide Interface Card

Double-wide interface cards can only be installed in interface card slots on Cisco 2800 series and Cisco 3800 series routers. See Figure 2 for a sample double-wide interface card.

Figure 2 Sample Double-Wide Interface Card

Cisco IOS Software Releases and Cisco Interface Cards

Cisco interface cards are often supported on multiple Cisco IOS releases. Cisco IOS release information is documented in the product data sheet and in Feature Navigator II.

To determine which Cisco IOS releases support your particular router and combination of cards and modules, go to the Software Advisor at http://tools.cisco.com/Support/Fusion/.

You must have an account on Cisco.com. If you do not have an account or have forgotten your username or password, click Cancel at the login dialog box and follow the instructions that appear.

Cisco Network Modules Supporting Cisco Interface Cards

Some Cisco network modules have interface card slots to allow installation of Cisco interface cards. These network modules have either one or two interface card slots, supporting either voice or data interface cards. See Figure 15 and Figure 16 for sample 1-slot and 2-slot network modules.

---

Note Some combination voice/data interface cards are supported on 1- or 2-slot network modules. However, interface card functionality is limited to either voice or data applications. See Table 1 for more information.

For information on installing interface cards onto network modules, see Installing Cisco Interface Cards in Cisco Access Routers.

For more information about Cisco network modules, see the Cisco Network Modules Hardware Installation Guide.

Cabling for Cisco Interface Cards

The cables required to connect the interface card to the network differ according to interface and connector type. See Table 2 for more information.

---

Note Cabling for 1- or 2-slot network modules is determined by the installed interface cards.

---

---

Note For network-end connectors and pinout specifications of the cables connecting the voice cards, refer to the Cisco Modular Access Router Specifications. Look under the type of interface card.
