As well, these new next-generation base stations whether WiMAX,HSUPA, or EV-DO Rev. A may actuallyrequire Ethernet connections. This relianceon Ethernet backhaul does present a chal-lenge as the vast majority of cell sites areonly served by TDM leased line. As a mobileoperator you are looking to deliver broad-band Ethernet services using your existingnarrowband TDM backhaul. You can notwait for, nor pay for, new fiber facilities. TheMX3112 is designed to address this challenge— the MX3112 allows operators to deliver 4Gservices over existing 2G mobile backhaul.The MX3112 maps Ethernet across DS1 orDS3 facilities to enable Ethernet servicedelivery over currently tariffed copper facili-ties. In its copper application mode, theMX3112 provides up to twelve DS1/E1 portsthat can be bonded for transporting the trafficof up to four client Ethernet ports. In its DS3application mode, the MX3112 provides DS3service for transporting the traffic of up tofour client Ethernet ports and up to 12 clientDS1 ports or five client E1 ports. Its compact 1RU size minimizes space allocation andprovides for dense utilization.The MX3112 may be used in a back-to-back architecture or as part of a system withthe OPTI-6100 as a Central Office aggregator.The OPTI-6100 aggregates up to twentyMX3112 systems, from multiple remote loca-tions, to a singe GigE port and passes throughTDM traffic.Ethernet over Bonded CopperMX3112MX3112VoiceBonded CopperVideo, InternetRNCBSCOPTI-6100 (MX)BondedHSPA, EV-DO, Mgmt.CDMA, GSM DS1LeasedT1, DS3Triple Play(2G, 3G, 4G)
