SM-X-1T3/E3 Cisco 4000 Series ISR Service Modules Interfacce Cards One port T3/E3 SM-X-1T3/E3 Overview The Cisco SM-X-1T3/E3 1-port T3/E3 enhanced service module (SM-X) is a software-configurable T3/E3 product for Second Generation Integrated Services Routers (ISR G2) and the Cisco 4451-X Integrated Services Router. This flexible enhanced service module enables you to switch between T3 and E3 applications with a single Cisco IOS command. The SM-X-1T3/E3 enhanced service module supports a single-port T3 or E3 with an integrated channel service unit (CSU) and a data service unit (DSU). It supports High-Level Data Link Control (HDLC), PPP, and Frame Relay. The SM-X-1T3/E3 includes the following features: Single portuniversal T3/E3 version Clear and subrate support in both T3 and E3 modes Online insertion and removal (OIR) support Onboard processing of Cisco Message Definition Language (MDL) and performance monitoring Support for scrambling and subrate can be independently or simultaneously enabled in each DSU mode Support for full T3 and E3 line rates Support for RFC1407MIB SM-X-1T3/E3= Specification SM-X-1T3/E3= Specification Miscellaneous (CDW) Compatible With Cisco ONE ISR 4451-X Networking Type Expansion module Form Factor Plug-in module Connectivity Technology Wired Interface Provided Qty 1 Type T3/E3 Header Compatibility PC Manufacturer Cisco Systems Packaged Quantity 1 Product Line Cisco Model SM-X-1T3/E3 Enhanced Service Module Brand Cisco Line Properties Line Rate T-3/E-3 T3/E3 Applications and Positioning The SM-X-1T3/E3 enhanced service module provides high-speed performance for advanced, fully converged networks supporting a wide array of applications and services such as security and advanced QoS for voice and video. T3/E3 and subrate T3/E3 connectivity optimizes WAN bandwidth for deploying new applications and service delivery. All supported platforms are capable of supporting full line rate performance but impose varying levels of CPU overhead and therefore affect the overall platform performance.
