The E1-L/R is a fractional E1 access device, for transmitting digital
data over framed (ITU-T G.704) E1 channels.
Digital data port rates are selectable for any multiple of 64 kbps
up to 1984 kbps. User data occupies only the required number
of E1 frame timeslots reducing billing to only bandwidth used.
E1-L/R also supports unframed E1 channels.
The E1-L/R is available in PCB for 3U high Cronyx Rack for 19 inch cabinet.
E1-L/R device may be ordered with multistandard interface. The multistandard interface
is cable-switchable to RS-232, RS-530, RS-449 or V.35 standards.
Device operation may be controlled via console port (RS-232 port for
supervisory terminal connection).
The E1-L/R device may be configured by DIP switches or from console.
Link testing and loopback control may be performed both from console
and from front panel.
