Juniper Networks ACX500 Universal Access 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 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 Routers 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 Maintenance (OAM) capabilities, and an open
software development kit (SDK) system that enables providers to customize and integrate
operations with their own management systems. For a list of related Junos OS
documentation, see http://www.juniper.net/techpubs/software/junos/
As part of the mobile backhaul, an ACX Series router at the cell site and an MX Series
router at the aggregation layer provide comprehensive end-to-end Ethernet, MPLS, and
OAM features with the one Junos OS running on both platforms.
