Routers Cisco 2900 Series - these are devices with integrated services of the second generation of the family ISR G2 (Integrated Services Router Generation 2). Series routers Cisco 2900 represented by 4 fixed and many extended models with licenses and modules. Routers Cisco ISR Series 2900 designed for small and medium enterprises that require modern technological solutions that provide reliable high-performance Internet connection with routing speed up to 75 megabits per second.
To the features of routers Cisco 2900 Series can be attributed gigabit ethernet ports with the possibility of switching to optics (SFP-connectors), Expansion slots EHWIC, compatible with previous generation modules WIC/ VWIC/ HWIC and expansion slots for modules SM (Service Modules), compatible with previous generation modules NM/ NME/ EVM. Also, there are internal connectors for modules ISM (Internal Service Modules), replacing AIM previous generation modules (ccompatibility with AIM Not) and internal connectors for digital signal processing modules (DSP) - PVDM3 to support voice and video functions (compatible with PVDM2). latest technology Services Ready Engine (SRE) providing separate, on request, deploying hardware and software services, and support VPN-networks using technology GETVPN, DMVPN and Enhanced Easy VPN with built-in hardware encryption features IPsec/SSL guarantees high scalability and high performance of all VPN protection and deployment services, and provides remote employees with secure access to company resources over a secure connection;
