The ACX1000 and ACX1100 Universal Access Routers are principally designed to provide
superior management for rapid provisioning to the access network. The ACX Series routers
support rich Gigabit Ethernet and 10-Gigabit Ethernet capabilities for uplink, along with
support for legacy interfaces and 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 are single-board routers with 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 ACX Series router is powered by Junos OS, supporting extensive L2 and L3 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 allows providers to customize
and integrate operations with their own management systems. For a list of related Junos
OS documentation, see

As part of the mobile backhaul, the ACX Series router at the cell site and the 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.
