The HJ-iAN7200 is a comprehensive access platform (MSAP) for dedicated customer line services and broadband IP data services, positioned at the edge of the metropolitan area network. It offers SDH 155M/622M upstream on the line side, along with GE upstream, supporting bidirectional transmission for SDH/MSTP and IP metropolitan networks. The user side provides various access methods such as SDH, PDH, Ethernet, PCM, and GSHDSL, flexibly meeting the access needs of large, medium, and small commercial customers, as well as 3G and NGN.
The HJ-iAN7200 utilizes 155M/622M optical ports to replace numerous traditional PDH devices' E1 electrical ports or fiber transceivers' Ethernet electrical ports, addressing the issue of excessive E1 copper lines or Category 5 cables, which lead to frequent failures and high maintenance costs. By converting E1, V35, and Ethernet services into VC12 for aggregation, convergence, and unified scheduling, it facilitates flexible business configuration, reducing the cost of space occupation for PDH PCM, microwave radio, fiber transceivers, G.SHDSL, and other equipment.
The HJ-iAN7200 combines the comprehensive OAM management functions of SDH with HengJie's unique remote network management technology, achieving full network management for access layer equipment and enhancing the operator's management and control capabilities over the access layer network.
HJ-iAN7200 is primarily designed for large-scale customer connections.
Feature Highlights：
Supports cross-connection capability for 16x16VC4 or 1008x1008 VC12.
2. Designed with telco-grade standards, supports 1+1 group path backup, enabling hot backup for group paths, cross connections, and clock modules; dual
Power backup and load sharing; 1+1 protection for branch circuit panels; hot-pluggable SFP optical interface card with full hot-pluggable support
Design
3. The back panel provides two bus systems: SDH and Ethernet; therefore, while providing STM-1/STM-4 upstream on the line side, it also offers 2 channels.
GE Upstream
4. Supports SDH channel and multiplex section protection, enabling various network topologies such as point-to-point, linear, ring, and ring-with-chain topology
5. Supports EOS functionality, utilizes GFP and LAPS encapsulation protocols, offers LCAS support, and is compatible with mainstream MSTP equipment manufacturers.
For passage;
6. Individual subframe supports up to 160 E1 lines or 80 Ethernet connections.
