Benefits of the ACX500 Router | 3
Juniper Networks ACX500 Universal Metro Routers are principally designed to provide superior
management for rapid provisioning to the access network. The ACX500 routers support rich Gigabit
Ethernet capabilities for uplink, along with support for Gigabit Ethernet interfaces, in a compact form
factor that is environmentally hardened and passively cooled. Seamless, end-to-end MPLS can be used
to address legacy and emerging requirements to provide the foundation for a converged network that
utilizes the same mobile backhaul infrastructure for business or residential services.
The routers have a built-in Routing Engine and one Packet Forwarding Engine. The Packet Forwarding
Engine has one "pseudo" Flexible PIC Concentrator (FPC 0). Because there is no switching fabric, the
single Packet Forwarding Engine takes care of packet forwarding.
• Routing Engine—Provides Layer 3 routing services and network management.
• Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route lookups, and
packet forwarding.
The Juniper Networks ACX Series Universal MetroRouters are powered by the Junos operating system
(Junos OS), which supports extensive Layer 2 and Layer 3 features, IP and MPLS with traffic engineering,
rich network management, fault management, service monitoring and Operation, Administration, and
