What primary functions does the Cisco WIC-2A/S provide for branch routers? +
The WIC-2A/S is a versatile WAN Interface Card designed to provide two serial ports for your Cisco router. It supports both asynchronous and synchronous serial data transmissions, making it ideal for connecting to external DSU/CSU devices, frame relay circuits, or managed WAN services in small-to-medium branch deployments.
Is the WIC-2A/S compatible with all Cisco modular router series? +
This module is compatible with a wide range of Cisco modular access routers, including the 1700, 1800, 2600, 2800, 3600, and 3700 series. Because compatibility depends on specific hardware slots and installed IOS versions, we recommend verifying your router’s chassis model and existing port density before integration to ensure optimal slot availability.
What is the maximum data rate supported by the WIC-2A/S ports? +
The WIC-2A/S supports synchronous serial speeds up to 128 Kbps per port. While it is not designed for high-speed multi-megabit backbones, it remains an industry-standard choice for legacy WAN connectivity, serial console server applications, and lower-bandwidth private line connections where reliability and stability are the primary project requirements.
How does the WIC-2A/S handle asynchronous traffic compared to synchronous? +
In asynchronous mode, this module is frequently used for dial-up connectivity or as a console server port to manage other equipment remotely. In synchronous mode, it handles time-division multiplexing for dedicated WAN links. Each port is software-configurable, allowing administrators to switch between these modes based on the specific requirements of the connected serial circuit.
Can I use the WIC-2A/S for hardware-based bridging or routing? +
Yes, this card integrates seamlessly into your router’s routing table, allowing you to treat each of the two ports as an individual interface. Once configured, you can apply standard Cisco IOS routing policies, access control lists, and security features to traffic passing through the serial interfaces, effectively treating them as any other physical network port.
What cabling is required to connect the WIC-2A/S to external devices? +
The WIC-2A/S utilizes a specialized 60-pin header that requires Cisco-specific serial cables. Depending on your remote equipment, you will need to select cables such as V.35, RS-232, RS-449, or X.21 connectors. Using original Cisco cabling is essential to ensure signal integrity and proper pinout configuration for both synchronous and asynchronous operations.
Does the WIC-2A/S require additional software licensing to activate? +
This hardware module does not require a specific feature license to operate. Once physically installed in a supported chassis, the router's IOS will automatically detect the WIC-2A/S. You only need to ensure your current IOS image supports the serial interface protocols required for your specific WAN circuit and configuration settings.
How should I configure the WIC-2A/S for an out-of-band management setup? +
To use the WIC-2A/S for out-of-band management, configure the ports for asynchronous operation and define them as auxiliary interfaces. This allows you to connect a modem or console cable to the serial port, granting you remote access to the router’s CLI if the primary network path fails, providing a critical layer of disaster recovery.
