With the requirements of communication services increasing, the value-added services (VAS) including 3D network games, video conference/phone, Video on Demand (VoD) and IPTV are key means for operators to provide differential services to attract more subscribers, and gain income growth. C220 (GCSA + EIG / EIGF / EIGM + EPFC / GPFA + TFANF ) ZXA10 C220 is big/middle OLT equipment with high density, high bandwidth and scalable office end equipment of passive optical access. It supports all kinds of FTTx application modes. ZTE ZXA10 C220 supports both in-hand NM and out-of-hand NM: In the in-hand NM mode, NMS information is transmitted through service channel of ZXA10 C220. It is flexible in networking without any auxiliary devices, and low in cost. But it is hard to maintain ZXA10 C220 when the service is down. In the out-of-hand NM mode, NMS information is transmitted through non-service channel. The management channel is independent from the service chennel. Thus out-of-hand NM is more reliable comparing with the in-hand NM. Features: 1.Easy for upgrade and migration 2.High density and performance design 3.Operable and manageable to save OPEX 4.Carrier class reliability to reduce operation 5.Multiple interfaces to meet requirements of different scenarios
