Because of the demand of the bandwidth growth of 3G/LTE services and the reduction of TCO, bearer networks are required to provide multiple flexible functions with low cost. ZXCTN 6150 is one of the best options to build a high efficient and power saving wireless bearer network, and benefit telecom operators in market extension & service innovation. ZXCTN 6150 supports Layer 2 and Layer 3 network or service interworking reliably and concurrently. It provides service providers a graceful migration path to a converged packet transport network based on MPLS/MPLS-TP. It enables connection-oriented characteristics of the traditional transport network such as SDH-like OAM, perfect protection mechanisms and powerful management, while maintaining the superior statistical multiplexing and flexible deployment of pure IP networks. The ZXCTN 6150 provides a wide range of interfaces with unmatched service flexibility. It enables service providers the ability to deliver mobile backhaul services, business-class IP and carrier Ethernet services, Asynchronous Transfer Mode (ATM) and Time Division Multiplexing (TDM) private leased line services at speeds from E1 to STM-4 and Ethernet services from 10 Mbps to 10 Gbps. The ZXCTN 6150 offers a switching capacity of 44 Gbps in a fully redundant, non-blocking shelf. Features Any Service, Any Channel, Any Port The ZXCTN 6150 can support Layer 1 to Layer 3 services on single platform with the flexibility of any service, over any channel and any port with the industry's most comprehensive and flexible multi-service interfaces supporting: IP, MPLS, ATM, GFP, TDM, pseudowire circuits and link aggregation. A variety of line cards are implemented to support packets, cells, TDM circuits, and mixing and matching of Fast and Gigabit Ethernet, optical and electrical, and multi-rate SDH physical line modules. Carrier-Class Reliability The ZXCTN 6150 is a fully redundant platform providing carrier-class reliability. It offers a perfect end-to-end protection mechanism for the services transported. At the access side, ZXCTN 6150 supports Link Aggregation Group (LAG), Virtual Router Redundancy Protocol (VRRP), Inverse Multiplexed ATM (IMA) E1 group and Linear Multiplex Segment Protection (LMSP) for the access links with STM-N. As to the network-level protection, the ZXCTN 6150 offers Linear Protection, Ring Protection and FRR. Especially the ZXCTN 6150 provides Dual-homing protection to enhance networks reliability when failures occurred at more than one point. Meanwhile NSF for service forwarding, Graceful Restart for protocols (such as OSPF, BGP, LDP and RSVP and so on) and hot standby redundancy for key components like switching card and power unit are all supported. The ZXCTN 6150 offers best-in-class high availability that is field-proven and time tested in more than a dozen carrier networks worldwide.
