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.
