DISTRIBUTED ANTENNA SYSTEM WITH MULTI-DROP CHANNEL LINE

摘要

The present invention relates to a distributed antenna system (DAS) with a multi-drop channel line. The DAS with a multi-drop channel line comprises a multi-drop channel line used as a DAS communication system, and allows backward control and state information/alarm information verification in subunits (a hub unit (HU) and a remote unit (RU)). Therefore, a subunit (RU) can communicate with a management server connected to a main unit (MU) and a different subunit (RU). Thus, control and state information/alarm information verification between the subunit (RU) and a control terminal can be performed even when the control terminal is connected to a subunit (RU) in any one location.
