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 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 with ITU-T V54 recommandation for diagnosticmanagement and tele- management, in point to point and multipoint mode.

This product comes from ASIC digicomtechnology 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.
