The E1-DXC device has four E1 interfaces. One E1 port can be replaced with serial multi-standard or Eternet interface. The multi-standard interface is switchable by adapter cable to RS-232, RS-530, RS-449 or V.35 standards. The E1-DXC provides n*64 Kbps (n = 1-31) cross-connect between any ports.

The device can be AC (220V) or DC (60V) powered and provided as a rack-mount 19'' 1U case (the device is also available as a stand-alone unit and as a card for 19'' 3U Cronyx rack.

The device setup and diagnostic mode control are performed via the RS-232 supervisory port, from remote device or via additional SNMP port.

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