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.
2

The ACX Series router is powered by Junos OS, supporng extensive L2 and L3 features, IP and MPLS
with trac engineering, rich network management, fault management, service monitoring and
Operaon, Administraon, and Maintenance (OAM) capabilies, and an open soware development kit
(SDK) system that allows providers to customize and integrate operaons with their own management
systems. For a list of related Junos OS documentaon, see hps://www.juniper.net/documentaon/
soware/junos/.
As part of the mobile backhaul, the ACX Series router at the cell site and the MX Series router at the
aggregaon layer provide comprehensive end-to-end Ethernet, MPLS, and OAM features with the one
Junos OS running on both plaorms.
The compact routers are one rack unit (U; that is, 1.75 in., or 4.45 cm) tall. Several routers can be
stacked in a single oor-to-ceiling rack for increased port density per unit of oor space.
The chassis is a rigid sheet metal structure that houses all the other router components. The chassis
measures 1.75 in. (4.45 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44.5 cm) wide. The outer edges of
the mounng brackets extend the width to 19 in. (48 cm) (from the front-mounng brackets to the rear
of the chassis). The chassis installs in standard 300-mm deep (or larger) enclosed cabinets, 19-in.
equipment racks, or telco open-frame racks.
Benets of the ACX1000 and ACX1100 Routers
•Space eciency—Conforming to the ETSI 300 specicaons, the ACX1000 routers are easy to
deploy in environments where rack space and cooling are limited.
•Improved operaonal eciency with zero-touch deployment (ZTD)—The ACX Series routers
support a zero-touch deployment (ZTD) model that signicantly reduces the me for any new
equipment installaon and provisioning, resulng in improved operaonal eciency.
•Installaon exibility with an environmentally hardened design—Most ACX Series routers are
temperature hardened and support passive cooling for outdoor deployments in extreme weather
condions.
ACX1000 Router Descripon
The ACX1000 routers contain eight T1/E1 ports and twelve Gigabit Ethernet ports, eight of which are
RJ-45 ports. The ports labeled COMBO PORTS provide an addional four RJ-45 ports or four Gigabit
Ethernet SFP ports. You can use only one set of combinaon ports at a me.

Packet Flow on ACX Series Routers
The class-of-service (CoS) architecture for ACX Series routers is in concept similar to that for MX Series
routers. The general architecture for ACX Series routers is shown in Figure 7 on page 10.
Figure 7: ACX Series Router Packet Forwarding and Data Flow
Based on the model, ACX Series routers contain a built-in Roung Engine and Packet Forwarding Engine
and can contain both T1/E1 and Gigabit Ethernet Ports.
The Packet Forwarding Engine has one or two “pseudo” Flexible PIC Concentrators. Because there is no
switching fabric, the single Packet Forwarding Engine takes care of both ingress and egress packet
forwarding.
Fixed classicaon places all packets in the same forwarding class, or the usual muleld (MF) or
behavior aggregate (BA) classicaons can be used to treat packets dierently. BA classicaon with
rewall lters can be used for classicaon based on IP precedence, DSCP, IEEE, or other bits in the
frame or packet header.
However, the ACX Series routers can also employ mulple BA classiers on the same physical interface.
The physical interfaces do not have to employ the same type of BA classier. For example, a single
physical interface can use classiers based on IP precedence as well as IEEE 802.1p. If the CoS bits of
interest are on the inner VLAN tag of a dual-tagged VLAN interface, the classier can examine either the
inner or outer bits. (By default, the classicaon is done based on the outer VLAN tag.)
Eight queues per egress port support scheduling using the weighted decit round- robin (WDRR)
mechanism, a form of round-robin queue servicing. The supported priority levels are strict-high and
default (low). The ACX Series router architecture supports both weighted random early detect (WRED)
and weighted tail drop (WTD).
All CoS features are supported at line rate.
10

The packet pipeline through an ACX Series router is shown in Figure 8 on page 11. Note that the rate
liming is done with an integrated architecture along with all other CoS funcons. Scheduling and
shaping are supported on the output side.

Protocols and Applicaons Supported by ACX Series Routers
Table 3 on page 12 contains the rst Junos OS Release support for protocols and applicaons on ACX
Series routers. A dash indicates that the protocol or applicaon is not supported.
NOTE:
• The [edit logical-systems logical-system-name ] hierarchy level is not supported on ACX Series
routers.
11

• The ACX Series routers does not support per-family maximum transmission unit (MTU)
conguraon. The MTU applied to family inet gets applied to other families as well, even
though it can be congured though CLI and visible in show interface extensive output. The only
way to use higher MTU for a family is to manipulate the MTU, apply at interface or family inet
levels, and let it calculate for each family automacally. MTU values are not limited to 1500
but can range between 256 to 9216.
