Large/ Middle Enterprise Core Router

Key Features and Benefits Using the network operating system platform, ROS (Routing Operating System) of BDCOM. Adopting a modular structure to provide rich and selectable modules. Data security: Supporting PAP, CHAP, RADIUS, VPN, VPDN, IPSec, IKE, firewall, backup solution. Multiple routing protocol support Dial-on-demand Routing (DDR). Supporting QoS: The router supports traffic classification and traffic policing, providing policies such as congestion management, congestion avoidance and traffic shaping. Supporting services of terminal server, which is mainly apply to the bank service system. This function implements smooth transition from the multiplexer access mode to the IP network access mode through the virtual terminal technology Voice features: BDCOM 3660 modular router supports VoIP voice features. For different circumstances, the following 3 types of voice ports can be selected accordingly: FXS, FXO and E&M.
