The FCD-IPL 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).
The FCD-IPL comes with an integrated IP router
supporting PPP. The internal IP router operates
in two modes: standard IP routing based on
static entries, RIP-1 and RIP-2; 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 host IP address.
QoS differentiation for VoIP, video
and data
The FCD-IPL transports 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.
Powerful network availability and
management features
FCD-IPL features a unique bidirectional 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 can be managed inband via Telnet,
Web-based applications and SNMP or out-of-
band via a direct connection to an ASCII terminal.
