A method and related apparatus for high speed digital data communications from multiple distributed modems to a single central modem (122) or a common transmission medium (80). In one embodiment, multiple downhole modems (130A, 130B, 130C), with each modem associated with a geophone (128A, 128B, 128C), transmit data to a surface modem over a single transmission medium. In a second embodiment, multiple transmission mediums are used and a plurality of downhole modems associated with geophones communicate to the surface modem over the down hole modem's respective transmission medium.
La présente invention concerne un procédé et un appareil associé permettant des communications de données numériques à grande vitesse, à partir de plusieurs modems répartis, vers un modem central unique (122) ou un support de transmission commun (80). Dans un mode de réalisation de cette invention, plusieurs modems de fond (130A, 130B, 130C), chaque modem étant associé à un géophone (128A, 128B, 128C), transmettent des données à un modem de surface, sur un support de transmission unique. Dans un second mode de réalisation de cette invention, de multiples supports de transmission sont utilisés et plusieurs modems de fond, associés à des géophones, communiquent avec le modem de surface, sur le support de transmission respectif des modems de fond.
