Cisco 3945E Series Integrated Services Router

The Cisco 3945E Series Integrated Services Router builds on the best-in-class offering of the existing Cisco 3800 Series Integrated Services Routers by now offering four platforms: the Cisco 3945E, Cisco 3925E, Cisco 3945, and Cisco 3925 Integrated Services Routers.

The Cisco 3900 Series offers embedded hardware encryption acceleration, voice- and video-capable DSP slots, optional firewall, intrusion prevention, call processing, voicemail, and application services. In addition, the platforms support the industry’s widest range of wired and wireless connectivity options such as T1/E1, T3/E3, xDSL, copper, and fiber Gigabit Ethernet.

The Cisco 3900 Series offers superior performance and flexibility for flexible network deployments from small business offices to large enterprise offices – all while providing industry-leading investment protection.

The Cisco® ISR G2 routers provide superior services integration and agility. Designed for scalability, the modular architecture of these platforms enables you to evolve and adapt with your growing business needs. Table 1 lists the business benefits of the Cisco 3900 Series.

Businesses need more intelligent branch-office solutions as they strive to lower the TCO for running their network and increase their overall employee productivity with more centralized and collaborative network applications. The Cisco 3900 Series offers these solutions by providing enhanced performance and increased modular density to support multiple concurrent services. The Cisco 3900 Series is designed to consolidate the functions of many separate devices into a single system that you can manage remotely. Table 7 lists the specifications of the Cisco 3945E, 3925E, 3945, and 3925 Integrated Services Routers.
