E1 and Fractional E1 Access Unit with Integrated IP Router

RAD's FCD-IPL E1 access unit with integrated router is a customer-located demarcation router for transporting 10/100BaseT Ethernet traffic over E1 or Fractional E1 links. It is ideal for supporting large scale rollouts of Layer 3 VPN services over E1 lines to small and medium-sized enterprises (SMEs).

• Facilitates large-scale IP VPN deployment to small and medium sized businesses

• Serves as a cost-effective demarcation device for transporting Ethernet over E1 or Fractional E1 links

• QoS for user traffic prioritization

The FCD-IPL, a compact and attractively priced E1 access unit with an integrated IP router located at the customer premises. The unit serves as a demarcation router, transporting 10/100BaseT Ethernet traffic over E1 and fractional E1 links. FCD-IPL access unit with integrated router comes with an integrated IP router supporting PPP. The internal IP router operates in two modes: standard IP routing based on static entries, RIP I and II; and transparent IP, in which frames received via the LAN/WAN interface are routed to the other interface, with the exception of management traffic which is sent to the FCD-IPL access unit with integrated router host IP address. The FCD-IPL access unit with integrated router is ideal for supporting large scale rollouts of Layer 3 VPN services over E1 lines to small and medium-sized enterprises (SMEs).

The FCD-IPL access unit with integrated router forwards Ethernet traffic at wire speed, enabling full use of the 2 Mbps link. The IEEE 802.3-compliant 10/100BaseT user port supports auto-negotiation and operates in both full and half duplex modes. Quality of Service (QoS) is assured, based on standard class of service definitions according to IP precedence (ToS) or DSCP. The user traffic is assigned to five distinct priority queues: one strict priority queue for VoIP and video applications and four weighted fair queues (WFQs) for data. The strict priority queue traffic is forwarded to the WAN link before traffic from any WFQ, minimizing delay and maintaining the quality of the transmission.

FCD-IPL access unit with integrated router features a unique bi-directional fault propagation mechanism that constantly monitors the status of the network and user connections. If a failure is detected on one of the interfaces, the FCD-IPL automatically shuts down the other port. The FCD-IPL access unit with integrated router can be managed in-band via Telnet, Web-based applications and SNMP or out-of-band via a direct connection to an ASCII terminal.
