Note: If you are having trouble getting a new circuit up, then set this value to ‘Half’ until
you resolve what is causing the problem. You should also turn off all but one drop on a
multi-drop line, and add more drops one at a time until they all work. If adding a drop
causes problems, check to ensure that the drop is configured to run in Half Duplex mode
and that the address of the new platform does not duplicate an address already in use.
Poll Timeout: This value determines how long the CNA-8000 is to wait for a response
before continuing through the poll list.
Line Type: The options for this are either ‘Leased’ or ‘Switched’. If the remote platform
will be dialing in, then set the Line Type for ‘Switched’. Otherwise set it for ‘Leased’. If
the Line Type is set to Switched, then the remote box should be configured to pass
IDBLK and IDNUM information in the form of an Exchange ID (XID).
Max Out: The value of this option determines the maximum number of outstanding
frames that the CNA-8000 will support on this line. The default value is 7.

edit the configurations of currently defined drops, and allow you to define new drops.
