This article applies to NET SatisFAXtion 8.5.


The CO emits a fast busy because the Fax Card slips the connection to the DID line.

NET SatisFAXtion 7.01 and 6.5.x installations using a Brooktrout TR-114 based DID fax card.
* To determine if your Brooktrout card is a DID card, check for an external -48V Power supply plugged into the fax card, externally at the back of your computer, on the face of the fax card. If you do not see this external power supply, you do not have a DID Brooktrout Fax Card
