Ethernet Demarcation Devices

  • Description

    BLUEBELL-ED series of Ethernet demarcation device on the basis of high-performance L2 switch service, provide convenience of maintenance and deployment, multi-service support, carrier-class OAM management, reliable protection mechanism, QoS policy, security mechanism, and other service optimization measures. Meanwhile, it features excellent extensibility and reliability.

    Product family supports the latest carrier Ethernet attributes and is compatible with IEEE, ITU, and MEF standards. The carrier-class OAM has enhanced network management capacity of carrier-class Ethernet and satisfies the operator’s requirements for comprehensive and powerful capacity of monitoring and management

  • Features
    • UNI & NNI supports 10/100M/1000M auto-negotiation, 10/100M/1000M full-duplex/half-duplex manual modes, AUTO-MDIX (Media Dependent Interface Crossover).
    • Circuit emulation of E1 and V.35 services on Ethernet link; SAToP protocol; MPLS, IP/UDP, and MEF encapsulation.
    • E1 and V.35 interface clock modes support local oscillator clock, adaptive clocking, and port loopback clock.
    • IEEE802.1Q VLAN and IEEE802.1ad VLAN (at most 4094 VLAN entries).
