The ACX2000 and ACX2100 Universal Metro 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 for radio and NodeB connectivity 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 ACX Series router is a single-board router with a built-in Routing Engine and one Packet Forwarding
Engine. Because there is no switching fabric, the single Packet Forwarding Engine takes care of both ingress
and egress 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.
