Main Benefits:

Uses software feature keys to scale WAN port configuration without the need for expensive hardware upgrades

Improves network reliability and performance through load sharing and load balancing in a multihoming environment

Offers flexible interfaces that can be deployed as independent links or bundled into one or more MLPPP or MLFR bundles

Supports broad range of routing protocols such as static routing, RIP1, RIP2, OSPF, optional BGP-4, IGMPv3, and GRE

Reduces access cost by integrating NAT services for Internet access

Better performance than many traditional branch office routers due to integrated hardware and software architecture

Lowers cost of ownership through integrated routing, CSU/DSU, optional Quality of Service, and network monitoring capabilities

The 5840 Multiport Router

When port density counts.

Quick Eagle’s 5840 Multiport RouterTM is ideal for medium-sized businesses and enterprise branch offices that need routers that can scale as the network requirements grow without having to add more hardware.

With its high port density, the 5840 Multiport Router delivers all the functions you need in a branch office router: The ability to configure static routes, and one or more dynamic routing protocols like RIP1, RIP2, OSPF, and optional BGP-4, enables the router to link enterprise networks with advanced IP routing services, such as multipaths and path redundancy.

Static NAT, dynamic NAT, and overloading (NAPT) lets you access the Internet using your private IP addresses. A stateful inspection firewall permits or denies access based on source and destination IP addresses. The embedded network performance monitoring features enable protocols and applications monitoring (RMON-1, RMON-2) and Frame Relay Service Level Verification.

In addition to its wealth of standard features, the 5840’s unique architecture provides the flexibility to meet the most demanding and evolving business requirements: Enabling your network to grow with your business, the 5840 Multiport Router can be upgraded for added bandwidth (up to 12 Mbps with 8 T1 or 16 Mbps with 8 E1 WAN ports) through software. No waiting for hardware, no engineering time to perform the upgrade, and no lengthy system downtime is required.

Multilink PPP (RFC1990) and Multilink Frame Relay (FRF.16.1) protocols provide the 5840 Multiport Router with the capability to bond multiple T1/E1s into a single high-speed virtual link or enable load balancing applications. The 5840 Multiport Router can also be deployed as a MAC Learning Bridge (IEEE 802.1d) over Frame Relay or PPP.

With its optional standard-based DiffServ QoS (Differentiated Services/Quality Of Service) capability the 5840 Multiport Router allows you to control and manage the bandwidth on your WAN connection, eliminating bottlenecks for your businesscritical applications such as ERP and CRM. In addition, DiffServ QoS enables delay-sensitive voice and video-over-IP services, while dedicating enough bandwidth for lower priority traffic.

With its excellent performance, scalability in routing protocols, breadth of features, and competitive pricing1, there is now an alternative to those traditional, high cost, proprietary branch office routers.

1 Please refer to Quick Eagle’s 5842 and 5844 Multiport Routers if you require a lower port density router with an even lower cost.
