Description
The Cisco SM-X-1T3/E3 Enhanced Service Module is a high-performance, single-port WAN interface designed to deliver flexible T3 or E3 connectivity for Cisco Integrated Services Routers. This service module enables seamless switching between T3 and E3 modes through software configuration, eliminating the need for separate hardware.
Engineered for enterprise and service provider environments, the SM-X-1T3/E3 integrates CSU/DSU functionality and supports full-rate and subrate T3/E3 services. It delivers reliable WAN transport for data, voice, and video applications while supporting common encapsulation protocols such as HDLC, PPP, and Frame Relay. Hot-swappable design and advanced performance monitoring make it an ideal choice for scalable and resilient network deployments.
