As 4G services and the applicable base
station architecture to deliver them become
available, Ethernet backhaul may become
your only option for effectively delivering
these new services. As well, these new next-
generation base stations whether WiMAX,
HSUPA, or EV-DO Rev. A may actually
require Ethernet connections. This reliance
on Ethernet backhaul does present a chal-
lenge as the vast majority of cell sites are
only served by TDM leased line. As a mobile
operator you are looking to deliver broad-
band Ethernet services using your existing
narrowband TDM backhaul. You can not
wait for, nor pay for, new fiber facilities. The
MX3112 is designed to address this challenge
— the MX3112 allows operators to deliver 4G
services over existing 2G mobile backhaul.
The MX3112 maps Ethernet across DS1 or
DS3 facilities to enable Ethernet service
delivery over currently tariffed copper facili-
ties. In its copper application mode, the
MX3112 provides up to twelve DS1/E1 ports
that can be bonded for transporting the traffic
of up to four client Ethernet ports. In its DS3
application mode, the MX3112 provides DS3
service for transporting the traffic of up to
four client Ethernet ports and up to 12 client
DS1 ports or five client E1 ports. Its compact 1
RU size minimizes space allocation and
provides for dense utilization.
The MX3112 may be used in a back-to-
back architecture or as part of a system with
the OPTI-6100 as a Central Office aggregator.
The OPTI-6100 aggregates up to twenty
MX3112 systems, from multiple remote loca-
tions, to a singe GigE port and passes through
TDM traffic.
