channel on the ESCON Director (= link address).

Connecting lines to the hosts
The connecting lines from the host adapter that go over the top of the screen show the host
devices connected.
The circle at the top of the line contains the device mnemonic. If the name is underscored
and the line continuous, the connection is active; the device is reserved and a logical path
has been established.
A dashed line indicates that a path has been established but no reservation exists.
If no line is displayed, no path has been established.
