Available in several configurations, Brooktrout TruFax Fax Boards provide up to four channels per board for dedicated send-and-receive-channel configurations. One-channel analog and two-channel BRI configurations are suitable for customers who have occasional faxing needs, but still require a very reliable fax solution. The two-channel analog and four-channel BRI configurations are generally used in network fax solutions. If Brooktrout TruFax Fax Boards are configured to send and receive faxes through separate channels, the fax solution can receive faxes in one channel and send faxes from the outbound job queue in another channel.

The table above lists the Brooktrout TruFax Fax Board models and some of their features. As of 2008, the ISDN telephony interface can be used in Europe and Japan. The table below provides ordering information.
