Output channels and destinations
Table 2 shows the output channels and destinations.
The system supports ten channels. By default, channels 0 through 6, and channel 9 are configured with
channel names and output destinations. You can change these default settings as needed. You can also
configure channels 7 and 8 and associate them with specific output destinations as needed.
You can use the info-center channel name command to change the name of an information channel.
Each output destination receives information from only one information channel, but each information
channel can output information to multiple output destinations.
