The E1-XLC device has two E1 ports (link 0 and link 1) and a digital port
(serial or Ethernet).
E1 stream from link 1, containing 64 kbit/s PCM coded voice timeslots,
is encoded to 16, 24, 32, or 40 kbit/s ADPCM data of link 0.
The rest of band is used for transmission of data from digital port.
E1-XLC device is transparent to signaling.
The ADPCM coding type is selectable from 14 possible variants.
The device is available as a stand-alone desk-top unit and can be AC (220V)
or DC (60V) powered.
The digital port can be equipped with V.35, RS-530, RS-232 or X.21
interface with the standard connectors, or multi-standard digital interface.
The multi-standard interface is switchable by adapter cable to RS-232,
RS-530, RS-449 or V.35 standards.
The device setup is performed by microswitches or via the RS-232 supervisory
port. All diagnostics options are controlled from the front panel or the
Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
