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.
