External channel select actions
External channel select override actions can enable, disable, or toggle the H/W
channel select system flag. This provides you with an additional layer of control
over how the current channel is selected.
When the base station enters Run mode, the flag is enabled.
When the flag is disabled, the channel is specified in software (Configure > Base
Station > General). The base station uses the default channel.
When the flag is enabled, the channel is specified by the Channel select lines
connected to the system interface card. The system interface must be configured
using the Service Kit to enable channel selection.
Other Task Manager actions can tell the base station to change
