Abstract
Aspects of the disclosure relate to methods and systems for adding or removing virtual channels from a terminal. A controller may send a virtual channel map to one or more terminals. The controller may also send a bitmask to one or more terminals. Each bit of the bitmask may indicate whether a virtual channel should be ignored. The channels that a terminal is permitted to receive may be altered by updating the bitmask.
