General Description:
The Ned-4182 ciphering system guarantees secure data transmission in G.703 and G.704 standards.
This system supports the ATM, PCM and Frame Relay protocols. The NED-4182 cipher/decipher data in transmitting or receiving with rate of 2Mbits/s.
In the special model wich could be installed in rack, totally 8 cards could be installed in the system so 8x2Mbit/s data could be transferred. This system includes hardware and software locks for increasing security.  Low current consumption, capability of connecting to 220VAC or 48VDC, independence from cooling fan, special alarm in plain mode, etc are some of the features in the system.  
 
Main Features:

  • 75/ 120 Ohm Output Impedance
  • Reporting And Programming Via PC 
  • Supporting G.703 and G.704 Standards
  • Emergency Clear  
  • Using New Ciphering Algorithm According To User Demand
  • Independent Code For Each Communication In E1 (PCM) Mode, For Increasing Security
  • Upgrading Via Software
  • Applying In Various Switches With PCM, Frame Relay, ATM,etc Standards
  • Automatic Detection Of The Ciphering System In the Other Side and  Automatic Switching TO Cipher Mode
