Since a lot of other's have already explained the repeater and heartbeat
problem, all I will add is they they are correct. A trick that I learned
about not too long ago that no one has mentioned is to put the DELNI in
remote mode and put an ethernet test plug in the remote port. The test
plug (probably not its official name) comes with a DESPR or DEMPR.

Hope this helps,
