Products Overview_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

Centralized, single-type-specific integrated service access multiplexer adopted large-scale integrated circuits, single-chip complete the signal processing of the optical port,E1 interface,the subscriber interface, mainly applied for the conversion from optic port (or E1 port) to the various types of data and voice interfaces. Intigrating of PCM and PDH,or PCM and SDH,the super compatibility of SPC10 Series solve the voice and broadband data services as well.Used in conjunction with PBX, it can achieve long-distance Telephone Number Service.They are widely applicable in integrated access of voice, data and images in telecommunications, electric power, finance, transportation, public security, army government,enterprises and other departments.

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

v      Height 1U(6U),width 19-inch,fixable 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, magnet interface,V.24/V.28 data interface(RS232/RS485), and synchronous transmission of V.24 interface, I TU 64kbps bi-directional data interface(G703), baseband interrupt interface, No.1 signaling and phone exchange cards

v     Consumate function control switch and the alarm indicator of sound and light on the pannel

v      Powerful network management platform

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

v     With Caller ID and polarity reversal signal

v     With the optical 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     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     Optical interface supports 1+1 double optic interfaces protection mode(in which one is backup)compatible with single mode, no need to replace devices;optic module 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 troubleshooting
