 Positioning and highlights

      As new generation compact full-service access equipment, ZXMP S325 supports smooth upgrade of capacity from STM-1/4 to STM-16, applicable to base station service access, key account service access and fixed-line IP service access. Hybrid networking of ZXMP S325 with other  MSTP equipments can deliver the most cost-effective solution for operators.

Powerful full-service access capability driving operators’ network development

       ZXMP S325 offers rich service interfaces, including STM-16, STM-4, STM-1 optical interfaces, STM-1, E3/T3, E1/T1 electrical interfaces, 10M/100M Ethernet interfaces, GE optical interface, as well as robust full-service support for ATM, EOS, RPR, delivering an integrated access layer solution to 3G base station service access, key account service access and fixed-line IP service access.

Outstanding scalability ensuring smooth evolution of network capacity

       With perfect smooth upgradeability, ZXMP S325 supports smooth upgrade of access layer capacity from STM-1/STM-4 to STM-16, strongly ensuring voice, data and video services to scale for capacity and maximizing customers’ investment return on equipments.

Be compatible with small-capacity requirements at convergence layer, enable network to extend downwards, facilitate roll out of customer services downwards from access node and boost network profitability.

Multiple measures to guarantee service security, network reliability and reduce OPEX

       1+1 configuration for cross-connect board and clock board, 1+1 hot backup for critical board;

Perfect electrical tributary 1:N protection function, simultaneous support for 2 groups 1:N protection, redoubled protection capability available for critical nodes and critical services;

Multiple protection modes including board power supply protection, sub-rack power supply access protection and cabinet power supply access protection.

Excellent product mix delivering an ideal total network solution

        Hybrid networking of ZXMP S325 with other ZXMP series equipments can deliver optimal product mix for option on demands at different nodes and at different network layers, and ZXONM E300 and ZXONM N100 can be used for centralized management, thus optimizing investment, driving down network construction cost and delivering the cost-effective solution.

Elaborate detailed design providing all benefits to customers

       System operation and maintenance adopt front-facing interfaces, front-facing operation and front-facing maintenance. Support wall-mounted installation, saving equipment room space and easing operation and maintenance;

        Support mixed insertion of slots, more flexible for equipment configuration and network planning & optimization;

      Highly integrated, only 5U in height, saving equipment room space;

      Low equipment power consumption resulting in reduced electricity expenditure.

  Technical highlights

• Robust RPR data features, in support of network IP-based evolution, future-oriented, investment protection

Support efficient statistic multiplexing for data services;

Support RPR span-ring, implement complex topological networking of crossing ring, tangent ring;

Strong data service awareness, support classes of services configuration based on IP priority, DSCP priority, TOS priority and offer complete QoS ability;

Multi-purpose board supports RoS, RoS+EoS, EoS application modes, enabling more flexible service configuration.

• Support mixed insertion of slots, more flexible for equipment configuration and network planning & optimization

ZXMP S325 can form multiple rings, with all line boards configured randomly. Elimination of the duality of eastbound and westbound slots eases network configuration, planning and optimization and boosts network flexibility.

• Universal design for service boards reducing spare part cost
