About the Cisco HWIC-1T Cisco network interface module
The Cisco HWIC-1T is a hot-swap High-Speed WAN Interface Card (HWIC) that installs directly into HWIC slots on compatible Cisco ISR platforms without requiring external power or additional cabling infrastructure. This single-port serial interface module delivers flexible WAN connectivity for network engineers deploying enterprise branch office and remote site solutions across distributed infrastructures.
The HWIC-1T supports multiple electrical standards—EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530 (via external cables)—through its 60-pin Smart Serial connector, enabling seamless integration with legacy and modern WAN equipment. The module supports industry-standard encapsulations including HDLC, PPP, Frame Relay, SLIP, and SMDS, making it suitable for diverse carrier protocols and network topologies. As a genuine Cisco product, it is eligible for Cisco TAC support validation and operates across Cisco IOS 12.3 and later releases on compatible ISR G1 platforms. The card operates reliably within 0°C to 40°C (32°F to 104°F) and complies with FCC Class A, CE, and RoHS regulatory standards.
Deployment Scenarios
- Branch office WAN connectivity on Cisco ISR 1841, 2801, 2811, 2821, 2851, 3825, and 3845 routers
- Legacy serial network integration for Frame Relay, HDLC, and PPP-based carrier services
- Modular slot expansion on HWIC-equipped ISR platforms without chassis replacement
- Multi-standard WAN termination supporting V.35, X.21, and EIA standards in mixed-vendor environments
- Remote site connectivity requiring hot-swap capability and field-replaceable interface cards
