& Modem
Eliminator...
LCM16P is a complete and reliable base bandmodem to
beusedinpointtopointandmultipointcommunicationson
2and4wiresleasedlines, infullduplexandhalfduplexwith
fixed and controlled carrier. This modem is suitable for
any telematic environment, for building, campus and
local loop needs.
LCM16P is compatiblewith 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 programand it is in conformity withITU-T V54
recommandation for diagnosticmanagement and tele-
management, in point to point and multipoint mode.
This product comes from ASIC digicomtechnology used
forDCE1(completelydigital modemfor CDNnetwork)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.
