Deployment Restrictions

1. No true hot-swap capability: The card cannot be safely inserted/removed while the router is powered on; power cycling the router is required for installation or replacement. Accidental live removal will not permanently damage hardware, but will cause instant link outages and system log errorsCisco.
2. Mixed-card compatibility: Multiple WIC-1T or other WIC-format cards can be mixed in the same router chassis without hardware conflicts, subject to router total power and slot resource limits.

3. Environmental Directive: EU RoHS hazardous substance restriction compliance

4. Core Deployment Advantages

1. Universal Multi-Standard Serial Port Flexibility: The DB-60 5-in-1 connector eliminates the need to purchase separate single-standard serial WIC cards. A single WIC-1T paired with interchangeable breakout cables supports all mainstream legacy serial WAN electrical interfaces, drastically reducing hardware inventory costs for multi-vendor serial leased-line deployments.
2. Dual Synchronous/Asynchronous Operation Support: The card simultaneously supports high-speed synchronous leased-line WAN interconnections for branch-to-headquarter data links and low-speed asynchronous serial connectivity for legacy industrial controllers, alarm systems and mainframe SDLC equipment, delivering unified hardware for mixed modern WAN and legacy infrastructure integration.
3. Broad Cross-Generation Cisco ISR Router Compatibility: WIC-1T works seamlessly across multiple generations of mid-range Cisco Integrated Services Routers from the 1600 series up to the 3700 series, enabling consistent serial WAN expansion for existing legacy router fleets without full chassis replacement.
4. Comprehensive IOS Feature Set Compatibility: Fully supports all core Cisco IOS routing, security, QoS and high-availability features on compatible routers, including dynamic routing protocols, traffic shaping for leased-line bandwidth control, access list security filtering, and dial backup for redundant WAN connectivity.
5. Low Power Passive Cooling Reliable Design: Fanless passive heat dissipation architecture removes mechanical fan failure points on the expansion card, improving long-term continuous operation reliability for unmanned remote branch equipment rooms. The low 8W typical power draw minimizes overall router power consumption and cooling load.
6. Cost-Effective Legacy Serial WAN Migration Solution: As a discontinued but widely available refurbished legacy WAN module, WIC-1T provides an affordable hardware alternative for enterprises and carriers maintaining existing serial leased-line WAN infrastructure, avoiding costly full router hardware refresh before complete fiber/IP migration.
