METHOD AND APPARATUS FOR MUTING A DIGITAL LINK IN A DISTRIBUTED ANTENNA SYSTEM
First Claim
1. A remote unit for a distributed antenna system (DAS), the remote unit comprising:
- a transmission path for converting digital data signals into an analog radio frequency (RF) signal;
a controller for monitoring events affecting the transmission path; and
a muting module coupled to the controller, wherein the muting module controls muting of a signal power of the transmission path as directed by the controller;
wherein the muting module applies a hard clamping to mute the signal power of the transmission path when the controller identifies an unplanned event;
wherein the muting module applies a ramp to mute the signal power of the transmission path when the controller identified a planned event.

Abstract
System and methods for muting a digital link in a distributed antenna system are provided. In one embodiment, a device for processing signals a distributed antenna system (DAS) is provided. The device comprises: a first signal path for transporting digital data signals; a controller for monitoring events affecting the first signal path; and a muting module coupled to the controller, wherein the muting module controls muting of a signal power of the first signal path as directed by the controller. The muting module applies a hard clamping to mute the signal power of the first signal path when the controller identifies an unplanned event. The muting module applies a ramp to mute the signal power of the first signal path when the controller identified a planned event.
