摘要
Similar to many cable operators. Rogers implemented a plant upgrade rather than a full rebuild because of the high cost of placing new buried cable in system rebuilds.The decision was to construct 600MHz two-way plant with a maximum of 10 trunk amplifiers and three line extender cascades with reverse bridger switching to isolate the reverse path in each 50- to 100-home feeder area.
