Maintenance (OAM) capabilies, and an open soware development kit (SDK) system that enables
providers to customize and integrate operaons with their own management systems. For a list of

As part of the mobile backhaul, an ACX Series router at the cell site and an MX Series router at the
aggregaon layer provide comprehensive end-to-end Ethernet, MPLS, and OAM features with the one
Junos OS running on both plaorms.
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 mounng brackets extend the
width to 19 in. (48 cm) (from the front-mounng 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-mounng kit
or the wall-mounng kit from Juniper Networks to mount the router in an outdoor environment.
Benets 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 producon-ready with lile or no manual
intervenon. As installaon and provisioning is faster, overall operaonal eciency is improved, and
the MPLS deployment in the access layer is simplied.
•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 implementaon, used for the aggregaon of small cell trac when the
backhaul is transported over the Internet.
•Advanced security services— ACX500 routers support IPsec, Media Access Control Security
(MACsec), Network Address Translaon (NAT), and Trusted Plaorm Module (TPM) features to
protect against potenal vulnerabilies to the network as well as subscriber trac.
