In a distributed enterprise, IT teams deploy the WIC-1T-1-Port Serial WAN Interface Card on Cisco ISR routers to establish dedicated T1/E1 serial links between head office and remote branches. This solution delivers reliable, low-latency WAN connectivity, enforces QoS policies for voice and data traffic, and simplifies network management through a single pane of glass. Businesses achieve consistent application performance, minimized packet loss, and predictable bandwidth utilization across geographically dispersed sites.
Manufacturing facilities use the WIC-1T-1-Port Serial WAN Interface Card to connect programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) units, and other legacy serial equipment to their IP networks. By leveraging the card’s robust DCE/DTE options and Cisco IOS serial encapsulation, engineers ensure secure data exchange, deterministic timing, and centralized monitoring. The outcome is streamlined plant operations, reduced downtime, and extended life of critical OT assets.
Enterprises implement the WIC-1T-1-Port Serial WAN Interface Card as a secondary serial link for mission-critical applications, providing automatic failover between primary broadband/MPLS circuits and legacy T1/E1 lines. In this scenario, Cisco IOS embedded performance routing (PfR) and IP SLA detect outages and reroute traffic in milliseconds. Organizations benefit from 99.99% uptime, uninterrupted voice/video conferencing, and enhanced SLA compliance.

The Cisco WIC-1T is a single-port serial WAN interface card that provides asynchronous and synchronous connectivity for Cisco routers.
The WIC-1T uses a single RJ-45 Smart Serial connector and requires an external cable for V.35, X.21 or RS-232 connectivity.
The WIC-1T is compatible with Cisco 1700, 2600, 3600, 3700 and 7200 series routers running Cisco IOS 11.x or later.
The WIC-1T supports synchronous serial speeds up to 2.048 Mbps and asynchronous speeds from 50 bps to 230.4 kbps.
Power down the router, insert the WIC-1T into an available WIC slot, secure it with the mounting screws, and then power on the router.
You need a Cisco Smart Serial cable or Smart Serial adapter cable that matches your service provider’s interface (V.35, X.21 or RS-232).
In global configuration mode enter interface serial <slot/port>, set encapsulation (for example PPP or HDLC), and assign the IP address under that interface.
Yes, the WIC-1T supports both PPP and Cisco HDLC encapsulation for WAN connections.
No, the WIC-1T is not hot-swappable; always power off the router before inserting or removing the module.
The WIC-1T draws approximately 1.5 W from the router backplane and does not require any external power source.
The WIC-1T is ideal for small-to-medium branch offices requiring low-speed WAN links, backup dial-up services or legacy serial connectivity.
Use the commands show controllers serial <slot/port> and show interfaces serial <slot/port> in privileged EXEC mode to view status and statistics.
Distance limits depend on cable type: up to 15 meters for V.35 and up to 100 meters for RS-232 when using appropriate Cisco cables.
The WIC-1T is supported on Cisco IOS 11.x and later releases that include Serial WAN service feature sets.
The Cisco WIC-1T carries a limited lifetime warranty against manufacturing defects when purchased through an authorized Cisco reseller.
