ZXMP P210 integrated service access equipment

ZXMP P210/P230 series products are small-sized, serial, integrated and intelligent PCM multiplexing equipment with network management functions.

ZXMP P210 integrated service access equipment offers a wide variety of simulation interfaces and data interfaces (V.35, G.703, 10BaseT, RS232/485). The equipment uses modular intelligent bus design, features simplified and clear structure, robust and flexible functions, simple debugging and maintenance and eased upgrade and capacity expansion. The centralized monitoring NM functions enable real-time monitoring for communications state of entire network. Flexible signaling setting function allows interworking of ZXMP P210 and other vendors’ PCM equipments via 2M. In chain networking, the strong ADM function makes it possible for free distribution of timeslots in 2M bandwidth. ZXMP P210 is applicable to access of subscribers in PTSN public network and dedicated networks like electric utility, railway and military networks, as well as access of DDN and Internet.

System features

• Modular design

The basic module contains 30 channels; maximal capacity is 60 channels, enabling flexible module overlaying on customers’ demands.

• A wide variety of data interfaces

Support for 64K codirectional interface (G.703), low-speed asynchronous data interface (RS232/485), N×64K synchronous data interface (V.35) and10BaseT Ethernet interface.

• Complete VF interfaces

User/switch analog interface, E/M trunk interface, loop trunk interface, interface for billing telephone (polarity inversion), magneto interface, hotline interface, carrier interface, 2/4-line VF interface.

• Flexible networking modes

Support for hybrid networking of point-to-point, chain, tree, star and ring.

• Perfect protection function

Provide 1+1 protection for power supply, ringing hot backup protection, surge and lightning protection, E1 path protection, power down and shoot-through protection in ADM mode and clock protection.

Benefits for customers

• Diversified interface and flexible networking

A wide variety of service interfaces (typical data, voice access, sub-rate multiplexing, synchronous RS232/485, broadband VF, voice shared wire, data shared wire interfaces) are available, fully meeting customers’ demands in railway, electric utility and military industry. Flexible signaling setting function facilitates interworking of ZXMP P210 and other vendors’ PCM equipments.

• Simple structure and eased maintenance

With modular intelligent bus design, ZXMP P210 has simple and clear structure, making it easy for debugging and maintenance, whilst facilitating upgrade and capacity expansion. All user service interface boards can be inserted in any slots, fully adapting to users’ requirement for changing service interface types and capacity.

• Cost effective solution protecting investment

ZXMP P210 can be deployed with other ZXMP equipments. Customers can select the optimal product combination on demand at different nodes and different network layers, and implement unified network management, thus optimizing investment and lowering network construction cost. It can directly connect 2M ports of a switch, instead of a PCM, saving FXO unit boards configured at central office and protection customers’ investment.
