Intelligent NG MSAP with Enhanced PTN Functions
As 3G is in vogue and 4G/LTE is coming, the current backhaul which often uses TDM/SDH technology cannot meet the need for bandwidth while maintaining a reasonable cost. It’s inevitable that the transportation network will be gradually transformed to packet switched networks. Moreover, more and more carriers have changed their service so that they can quickly orient themselves to this new trend. The manufactures are also trying to deliver dependable and future-proved solutions in order to help carriers to smooth the incoming transition.
iTN2100, as the upgrade and update product of OPCOM3500E, possesses SDH and PTN dual cores. It inherits the basic distinguishing feature of MSAP and improves the cross connection capacity of SDH. Besides, instead of previous four VC4 capacity limitations, now the capacity is up to 16 VC4. In the traditional network, it can offer large customer service access with higher convergence ratio. For the PTN core, each slot Ethernet bandwidth of IP BUS had improved from 1xFE to 2xGE. The switch card supports card redundant protection to provide higher reliability, at the same time, it also supports label switching, Ethernet loop protection, OAM and SLA function. Based on all of these function iTN2100 can achieve different services carried on different network neatly so that realized the transition from traditional service to packet switch service. Then it can help carriers to solve the cost problem which come from change the remote device, and it also can prolong the equipment’s lifespan.
iTN2100 is a multi-service access aggregation product, which can be compatible variety of service types, including SDH/IP switch/FiberMux/CWDM/EoTDM/TDMoIP/Media convertor and DS3/E3/E1/GE/FE/FX/G.SHDSL/V.35/V.24 service interfaces as well. Therefore, it can provide customers with 3G/4G/LTE backhaul, business connection, enterprise optical access, large capacity traditional copper G.SHDSL aggregation and CWDM optical transmission applications.
