    Cisco 1941 Router

    Cisco 1941 Router: Cisco1941 builds on the best-in-class offering of the existing Cisco 1841 Integrated Services Routers by offering 2 models - Cisco 1941 and Cisco 1941W. In addition to the support of a wide range of wireless and wired connectivity options supported on Cisco 1941 Series, Cisco 1941W offers integration of IEEE 802.11n access point which is backwards compatible with IEEE 802.11a/b/g access points.

    All Cisco 1900 Series Integrated Services Routers offer embedded hardware encryption acceleration, optional firewall, intrusion prevention, and application services. In addition, the platforms support the industries widest range of wired and wireless connectivity options such as T1/E1, xDSL, 3G, 4G LTE, and GE.

     

    Cisco 1941 Integrated Services Router:

    The Integrated Services Routers Generation 2 (ISR G2) routers provide superior services integration and agility. Designed for scalability, the modular architecture of these platforms enables you to grow and adapt with your business needs.

    The Cisco 1941 Series offer increased levels of services integration with data, security, wireless, and mobility services enabling greater efficiencies cost savings.

    High Performance with Integrated Services

    The Cisco 1900 Series enables deployment in high speed WAN environments with concurrent services enabled up to 25 Mbps

    Multi-Gigabit Fabric enables high bandwidth module to module communication without compromising routing performance.

     

       Designed to address customer business requirements, Cisco 1941 Series with the modular architecture, offers performance range of modular interfaces and services as your network needs grow.

    Modular interfaces offer increased bandwidth, a diversity of connection options, and network resiliency.

    The Cisco 1941 Series maximizes investment protection by supporting:

       Reuse of a broad array of existing modules supported on the original Integrated Services Routers provides a lower cost of ownership.

       Rich set of Cisco IOS Software features carried forward from the original Integrated Services Routers and delivered in the universal image.

       Flexibility to grow as your business needs evolve.

     

    Architecture and Modularity

    The Cisco 1941 Series is architected to meet the application demands of today’s branch offices with design flexibility for future applications. The modular architecture is designed to support expanding customer requirements, increased bandwidth, and fully integrated power distribution to modules supporting 802.3af Power over Ethernet (PoE) and Cisco Enhanced PoE (ePoE). Table 2 lists the architectural features and benefits of the Cisco 1941 Series.

     

    The Cisco 1941 Series ISR are highly modular platforms with multiple module slots to provide connectivity and services for varied branch network requirements.

      The ISRs offer an industry-leading breadth of LAN and WAN connectivity

     

    The Cisco 1941 Series is powered by high-performance multi-core processors that support growing demands of branch office networks by supporting high throughput WAN requirements.

    The Cisco 1941 introduces an innovative MultiGigabit Fabric (MGF) which allows for efficient module to module communication, enabling direct services interactions across modules while reducing the overhead on the router processor.

      Embedded hardware encryption acceleration is enhanced to provide higher scalability, which, combined with an optional Cisco IOS Security license, enables WAN link security and VPN services (IPSec acceleration).

      The onboard encryption hardware out-performs the Advanced Integration Modules of previous generations.

    All onboard WAN ports are 10/100/1000 Gigabit Ethernet WAN routed ports

     

    A new, innovative, mini-B USB console port supports management connectivity when traditional serial ports are not available.

      The traditional console and auxiliary ports are also available. Either the USB-based console or the RJ-45-based console port can be used to configure the router.

     

    The Cisco 1941 provides significantly enhanced modular capabilities (refer to Table 2) offering investment protection for customers. Most of the modules available on previous generations of Cisco routers, such as the Cisco 1841 ISR, are supported on the Cisco 1941. Additionally, modules used on the Cisco 1941 can easily be interchanged with other Cisco routers to provide maximum investment protection. Taking advantage of common interface cards across a network greatly reduces the complexity of managing inventory requirements, implementing large network rollouts, and maintaining configurations across a variety of branch-office sizes.

    TheEHWIC slot replaces the high-speed WAN interface card (HWIC) slot and can natively support HWICs, WAN interface cards (WICs), wireless WAN 3G/4G LTE, voice interface cards (VICs), and voice/WAN interface cards (VWICs).

      Two integrated EHWIC slots are available on the Cisco 1941 for flexible configurations for support of two modules: One double wide HWIC-D or single wide EHWIC/HWIC module and a second single wide E-HIC/HWIC module are supported.

      Each HWIC Slot offers high data throughput capability.

       Up to 1.6 Gbps aggregate towards the router processor.

       Up to 2 Gbps aggregate to other module slots over MultiGigabit Fabric (MGF).

    Asingle ISM Slot provides flexibility to integrate intelligent services modules that do not require interface ports.

      ISM replaces the Advanced Integration Module (AIM) slot; existing AIM modules are not supported in the ISM slot.

      Each ISM Slot offers high data throughput capability.

       Up to 4 Gbps aggregate towards the router processor.

       Up to 2 Gbps aggregate to other module slots over MultiGigabit Fabric (MGF).

      Power to ISM slots can be managed by extensions similar to the Cisco EnergyWise framework, allowing organizations to reduce energy consumption in their network infrastructure. Full EnergyWise support will be available in future software releases.

    Integrated LAN Switching

    The Cisco 1941 Integrated Services Router Series will support the EHWIC LAN modules when they become available in future. The Cisco 1941 Series support the existing single wide EtherSwitch HWIC and the double wide HWIC-D modules, which greatly expand the router’s capabilities by integrating industry leading Layer 2 or Layer 3 switching.

    Application Services

    As organizations continue to centralize and consolidate their branch IT infrastructure in an effort to reduce cost and complexity in the branch office, they are challenged to provide adequate user experience, ensure continuous service availability, and deliver business-relevant applications when and where they are needed. To address these challenges, the Cisco 1941 Series provides the ability to host Cisco, 3rdparty, and custom applications on Cisco Services Ready Engine (SRE) module that seamlessly integrate into the router. The module has its own processor, network interface, and memory that operate independently of the host router resources, helping to ensure maximum concurrent routing and application performance while reducing physical space requirements, lowering power consumption, and consolidating management.
