Multiplexer-Crossconnector E1-DXC


Multiplexer-Crossconnector E1-DXC Features:
  • Four E1 ports
  • Synchronous V.35/RS-530/RS-449/RS-232 or Ethernet interface (optional)
  • ITU G.703, G.704, G.706 and G.823 compliant
  • Up to 1.5 km
  • CAS and CRC4 framing
  • 128 x 128 non-blocking switching matrix
  • Sa bits translation
  • Clock sources: Internal oscillator, E1 receiver or synchronous port
  • Master & backup clock sources
  • Asynchronous mode for RS-232 interface
  • Digital and line loopbacks
  • Integrated HDLC buffer
  • Integrated BER tester
  • Supervisory RS-232 port
  • Dry contacts alarm interface
  • AC or DC power
  • Upgradeable firmware
  • Certificate N OS-2-SP-1638

The E1-DXC device has four E1 interfaces. One E1 port can be replaced with serial (V.35, RS-530, RS-232, X.21) or Eternet interface. The E1-DXC provides n*64 Kbps (n = 1-31) cross-connect between any ports.

The device is available as a stand-alone desk-top unit and can be AC (220V) or DC (60V) powered.

There is a choice of V.35, RS-530, RS-232, X.21 with the standard connectors or multi-standard digital interfaces. The multi-standard interface is switchable by adapter cable to RS-232, RS-530, RS-449 or V.35 standards.

The device setup and diagnostic mode control are performed via the RS-232 supervisory port.

Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
