Technical Specifications:

 Features                                                                    

v       Reliable large-scale integrated chips

v       Artificial intelligence panel setting interface

v       Clock mode: master clock,E1(optional function)clock,subscriber clock.etc.

v       Height 1U(6U),width 19-inch,fixed arbitrarily more than 20 kinds of interface cards

v       64kbps-rich user interfaces: FXO, FXS, EM2/4-wire audio interface, Ethernet interface, V.35

data interface,hot line interface, magnetic interface, 2100Hz carrier magnetic card,V.24/V.28 data interface(RS232/RS485), and V.24 interface with data and clock synchronous transmission, I TU 64kbps bi-directional data interface(G703), baseband interrupt interface,No1 signaling and phone exchange cards

v       Enhanced function and flexibility in the application: it can provide 1 ~ 8 transmission directions of E1 line : built-in cross-connect matrix facilitate the complex chain net and star-shaped net

v       Consumate function control switch and the alarm indicator of sound and light on the pannel：When the optical inetrface or E1 interfaces alarm occurs when the alarm of the sound and light can be issued

v       Powerful network management platform: simple and comprehensive network management features, you can configure the device inquiries, fault statistics and management online . Business of users will have real-time online distribution network, broadband of users can be adjusted at any time

v       Network management interfaces: RS-232 serial interface and 10/100Base-T Ethernet

v       Flexible signaling changes with the road pattern, easy to be on the pass with other manufacturers, or single-side access

v       With Caller ID and polarity reversal signal

v       With the optic interface transmission,the line speed of Ethernet interface can reach  fast, providing transparent transmission of E1 interface and user-friendly to expand

v       ADM features a powerful and flexible distribution of time slots in 2M

v       Power: AC and DC optional 

v       Link side optoelectrical inetrface switching(E1/optic interface) can be freely finished by switch, unneccesary to change equipment

v       The transmission of single fiber/dual fiber,single /multi-mode, the modes of short-distance/long-distance(20 KM/40 KM/120 KM) can be flexibly switched, no need to replace devices

v       The functional card is designed in modules,and interfaces can be plugged or pulled into different combinations

Eg:uplink E1interface:8 channel FXO/FXS + 4 channel Ethernet/100M+1v.35(N*64Kbps)

v       Optic interface supports 1+1 double optic interfaces protection mode(in which one is backup)compatible with single mode, no need to replace devices;optic modules supports hot pull and plug

v       SDH/PDH/E1, small in size,compact in design, can provide a variety of audio or data transmission services.By using the switches on the front board,uplink interface can be changed freely from E1(G.703) to PDH or SDH optic interface,no need to change devices

v       All the interfaces have the function of protection against lightening strike.

v       Greatly facilitate the daily work of installation and maintenance troubles
