specifies how many times the user device will be polled (if it is not responding) before
control is passed on the next cluster (accompanied by other condition checks).

device is unable to acknowledge; that is, returns a NAK to the FRX8000.

polls. It is activated after a session is over; i.e., an EOT (End of Transmission) is suc-
cessfully transmitted down the line. On expiry, a general poll is transmitted, except
under certain special conditions. The timer is deactivated at Link Down.
