# Maximizing ports for fax transmission

The following table shows the maximum number of IVR and fax transmit ports that specific boards can support. The table also lists the example configuration files.

This performance strategy achieves the highest number of ports per board, but all ports may not support all operations. Some of the hardware configurations listed can support only IVR and fax transmit operations, and cannot support fax receive operations on any ports. If you need fax receive capability, configure the system for maximizing universal ports.

The AG 2000/400 board provides DSPs for up to 16 ports of IVR and fax, but only eight line interfaces. Eight additional line interfaces must be provided with additional hardware.

Note: These calculations are valid for both CompactPCI and non-CompactPCI boards.
