The Cisco DSU/CSU T1 (Part Number: WIC-1DSU-T1) is a WAN Interface Card designed for Cisco routers, enabling integrated service for digital lines by providing direct access to T1 circuits. This compact module supports data rates up to 1.544 Mbps, ensuring robust and consistent performance for enterprise-level networking needs. The card combines DSU (Data Service Unit) and CSU (Channel Service Unit) functions into a single unit, eliminating the need for an external DSU/CSU device while reducing overall installation and configuration complexity.
One of the important features of this interface card is its integrated T1 termination, which is critical for terminating T1 circuits directly within your router. The WIC-1DSU-T1 connects LAN networks to WAN links and includes diagnostic capabilities that facilitate troubleshooting and performance monitoring of the T1 line. With built-in support for both protocol and circuit configuration management, this card is designed to maintain high availability and throughput across the T1 network.
Compact in size, the WIC-1DSU-T1 fits directly into the appropriate WIC slots on supported Cisco routers. Another feature is the card’s loopback diagnostic support, which helps ensure effective line testing to detect and resolve any issues without requiring additional external hardware testing tools. This WAN card also supports advanced traffic queuing and multiple encapsulation methods including HDLC and PPP, making it adjustable for various networking demands.
This model is ideal for businesses requiring reliable, high-speed connections to branch offices or external service providers using T1 service. The card’s seamless integration with existing Cisco infrastructure guarantees continued network connectivity with minimal downtime during installation or configuration adjustments.
