1. A distributed antenna system comprising:
- a master unit having first circuitry;
a first remote unit having second circuitry and communicatively coupled to the master unit; and
a second remote unit having third circuitry and communicatively coupled to the master unit;
wherein the first remote unit is configured for;
receiving analog downlink RF signals from a base station,converting the analog downlink RF signals to digital downlink signals, andproviding the digital downlink signals to the master unit;
wherein the master unit is configured for;
transmitting the digital downlink signals received from the first remote unit to the second remote unit;
instructing the first remote unit to establish a communication link with the base station in response to detecting a malfunction with respect to an additional communication link between the master unit and an additional base station.

Abstract
A remote unit of a distributed antenna system is disclosed that can communicate analog RF signals with both base stations and terminal devices in a coverage zone serviced by the remote unit. In some aspects, the remote unit can include a signal processing module and a transceiver. The transceiver can communicate RF signals between a master unit of the distributed antenna system and a terminal device. The transceiver can also receive analog downlink RF signals from a base station. The signal processing module can convert the analog downlink RF signals to digital downlink signals and provide the digital downlink signals to the master unit.
