Specification:
    The E3012series cabinet type Protocol Converter adopts modularization design, providing various Protocol Convert module to mix-plug, which can exchange between 1~4 E1-Ethernet, E1-V.35 , V.35-Ethernet etc. interfaces as well as several interfaces(10/100 Bases-T, E1,V.35 )optical/ electricity conversion.through the management module to realize unified management and supervise and control a distant equipments also. Concentrated type interface converter design specialize just for big scope network layout, it can be installed in 19 inch standard machine cabinets, the height is 4 Us, AC or the DC power supply method arbitrarily, can insert 12 pieces data business cards and each card works independently, the data business card of different type can be pluged into the same machine to work in the meantime; Concentrated type interface converter machine adopts communication insulation technique to isolate the system power supply and the data business card completely and independently thus assure the whole system to work safely and reliablely. The equipments’ back panel provides all connecters, after the data business card being inserted into the slot and through electricity, the front panel LED will display the circuit stage, the back panel then provides the BNC and Twisted Pair Cable connecter of E1; 10/100 Bases-T net bridge, and exchange data connecter of DB25 into the via adaptive cable and can connect the data of the DB25 into V.35, RS530, RS449, X.21 etc. connecters.

 Key Features:
 ●Can mix-plug 12 pieces of data business card at most(interface Converter card,
    ethernet bridge, fiber-optic modem card etc.)
 ●Super port density, Can provide 96 E1 ports at most,24 Vs.35 Connect.
 ●19 inches 4U concentrated standard cabinet, well radiation,system operation stability,
    easy toManage and maintain.
 ●Provide Telnet, local serial, telephone dail-up, SNMP etc. various management methods,
    supporting OLYCOM’S OMview management system.
 ●Adopt the modularization power supply design, easy to maintain; preventing from
    electromagnetism signal interference that brings forth by power supply.
 ●All data business card and power supply support hot- plug.
 ●Double power supply redundancy hot spare to assure the reliability and stability of the whole
    system circulatation.
 ●Meeting the telecommunication operation requests completely, more than 50,000 hours
    normal work time.
 ●Each data business card has abundant LED circuit state display.
 ●The back panel provides E1 and all kind of data interface.
