  • Offset frequency multipoint modem and communications network
    Patent number: 5052024
    Abstract: In a multipoint data communications system used with analog communications channels that may insert undesirable frequency offsets in a modem carrier frequency, a slave modem that adjusts its transmit carrier frequency compensates for the offset influenced communications channel. A central modem device does not have to train up to slightly offset frequencies when the communications channel is effectively removing the offset added by a slave modem at its transmitter site.
