Base Band modem
&
Modem
Eliminator...
LCM16P is a complete and reliable
base band
modem to
be used in point to point and multipoint communications on
2 and 4 wires leased lines, in full duplex and half duplex with
fixed and controlled carrier. This modem is
suitable
for
any telematic environment, for
building
,
campus and
local
loop needs.
LCM16P is
compatible
with any base band modem, it can
be used on leased lines which are lent by your public
manager, owner of the lines themselves.
It is easy to
program
and it is in conformity with
ITU-T V54
recommandation for
diagnostic
management and tele-
management, in point to point and multipoint mode.
This product comes from
ASIC digicom
technology used
for DCE1 (completely digital modem for CDN network) and
it is carried out also into version at
64 Kbit for special
connections
(LCM16P64) at high speed in local point to
point environment without cascade connections.
