Benets of the ACX500 Router | 3

Juniper Networks ACX500 Universal Metro Routers are principally designed to provide superior

management for rapid provisioning to the access network. The ACX500 routers support rich Gigabit

Ethernet capabilies for uplink, along with support for 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 have 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.

The Juniper Networks ACX Series Universal MetroRouters are powered by the Junos operang system

(Junos OS), which supports extensive Layer 2 and Layer 3 features, IP and MPLS with trac engineering,

rich network management, fault management, service monitoring and Operaon, Administraon, and

2

Maintenance (OAM) capabilies, and an open soware development kit (SDK) system that enables

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, an ACX Series router at the cell site and an 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 ACX500 routers can be installed indoors as well as outdoors:

•ACX500 indoor—The compact ACX500 indoor 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 of the ACX500 indoor router 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.

•ACX500 outdoor—The compact ACX500 outdoor routers are environmental hardened, and can be

deployed in an outdoor environment, such as on walls and poles. The chassis of the ACX500 indoor

router measures 1.75 in. (4.45 cm) high, 9.4 in. (24 cm) deep, and 17.5 in. (44.5 cm) wide. The chassis

of the ACX500 outdoor router with the Power over Ethernet (PoE) unit measures 16 in. (40.64 cm)

high, 4.7 in. (11.93 cm) deep, and 10 in. (25.4 cm) wide. You need to purchase the pole-mounng kit

or the wall-mounng kit from Juniper Networks to mount the router in an outdoor environment.

Benets of the ACX500 Router

•Zero Touch Provisioning (ZTP)—ZTP enables quick deployment of a large number of ACX 500

routers. As the ACX500 supports ZTP, it can be producon-ready with lile or no manual

intervenon. As installaon and provisioning is faster, overall operaonal eciency is improved, and

the MPLS deployment in the access layer is simplied.

•Integrated high-precision ming (Synchronous Ethernet and Precision Time Protocol)— You can use

the ACX500 routers for Synchronous Ethernet and PTP in a hybrid mode for the highest level of

frequency (10 ppb) and phase (<500 nS) accuracy required for LTE-A. The ACX500, ACX500-O, and

ACX500-O-PoE routers also provide an integrated GPS receiver and can act as a grandmaster (GM)

clock for a distributed PTP implementaon, used for the aggregaon of small cell trac when the

backhaul is transported over the Internet.

•Advanced security services— ACX500 routers support IPsec, Media Access Control Security

(MACsec), Network Address Translaon (NAT), and Trusted Plaorm Module (TPM) features to

protect against potenal vulnerabilies to the network as well as subscriber trac.

3

•Environmentally hardened design—ACX500 routers are temperature hardened and support passive

cooling for outdoor deployments in extreme weather condions. The ACX500-O and ACX500-O-

PoE routers are based on environmentally hardened, ruggedized chassis and are IP65-compliant for

outdoor deployments (pole mount or stand mount) with no need for an enclosure or cabinet.

•High availability and reliability— Junos Connuity on ACX500 eliminates OS upgrades and system

reboots when new hardware is added to ACX500 routers. A plug-in package provides the drivers and

support les needed to bring the hardware online.

Unied in-service soware upgrade (unied ISSU), provides soware upgrades between two

dierent Junos OS releases (major or minor) without disrupng network trac.

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 4 on page 11.

Figure 4: 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.
