ACX1100 Router Descripon | 4
The ACX1000 and ACX1100 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 capabilies 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 foundaon for a converged network that ulizes the same mobile backhaul infrastructure
for business or residenal services.
The routers are single-board routers with a built-in Roung 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.
•Roung Engine—Provides Layer 3 roung services and network management.
• Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route lookups, and
packet forwarding.
