HJ-iAN7200 is a comprehensive access platform (MSAP) designed for customer dedicated line services and broadband IP data services. It is positioned at the edge access layer of metropolitan area networks. The iAN7200 provides SDH 155M/622M uplink on the line side, as well as GE uplink, supporting SDH/MSTP and IP metropolitan networks with bidirectional bearer services. On the user side, it offers various access methods such as SDH, PDH, Ethernet, PCM, and GSHDSL, flexibly meeting the access needs of various large customers, small and medium commercial customers, 3G, and NGN for operators.
HJ-iAN7200 uses 155M/622M optical ports to replace a large number of traditional PDH devices' E1 electrical ports or optical transceiver Ethernet ports, solving the problems of frequent faults and high maintenance costs caused by excessive E1 copper wires or Category 5 cables. By converting services such as E1, V35, and Ethernet into VC12 for aggregation, convergence, and unified scheduling, it facilitates flexible service configuration and reduces the space occupancy costs of equipment like PDH PCM, multiplexers, optical transceivers, and GSHDSL in equipment rooms.
HJ-iAN7200 combines the comprehensive OAM management functions of SDH with Hengjie’s unique remote network management technology to achieve full network management of access layer devices, enhancing operators' management and control capabilities over the access layer network.
HJ-iAN7200 is mainly aimed at high-capacity customer access.
1. Supports 16x16 VC4 or 1008x1008 VC12 cross-connection capability;
2. Based on telecom-grade product design, supports 1+1 backup for group boards, achieving hot backup for group, cross, and clock modules; dual
power backup and load sharing; supports 1+1 protection for branch boards; uses SFP hot-swappable optical interface boards for full hot swapping without interruption
design;
3. The backplane provides two sets of buses: SDH and Ethernet; therefore, while providing STM-1/STM-4 uplinks on the line side, it also provides 2 GE uplinks;
GE uplinks;
4. Supports SDH channel and multiplex section protection, enabling various network topologies including point-to-point, chain, ring, and ring-chain types;
5. Supports EOS function, uses GFP and LAPS encapsulation protocols, supports LCAS function, and is compatible with mainstream MSTP vendor equipment
interconnection;
6. A single subrack supports up to 160 E1 or 80 Ethernet accesses;
7. Can interoperate and remotely manage with Hengjie Ethernet fiber transceivers, PDH optical terminals, Ethernet multiplexers, protocol converters, PCM, SDH multi-service
optical terminals and other products;
8. Supports built-in DCN management channel to solve the problem of insufficient coverage of operator DCN networks at the access layer; supports cascading of multiple subrack
management levels;
9. Provides built-in error code instrument function and remote device power-off alarm function;
10. Supports Ethernet loop detection function;
11. Supports network management platform for online software upgrades of local device boards and remote devices.
