# Maximizing universal ports

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

Universal ports can run any IVR or fax operation. In some configurations, using the maximum number of universal ports means none of the remaining ports can be used. Under these conditions, each available port can support all operations, but all ports on the board may not be available. This performance strategy provides the best functionality per port.

For fax-only applications not requiring IVR functions, use the universal port configuration files and number of ports-per-board guidelines in this section.

Maximum universal (fax and IVR) ports per board | Configuration file for...
--- | ---
Board | Ports | Restrictions | mu-law | A-law
AG 2000/200 | 8 | None | agpi2fax.cfg | agpi2faxa.cfg
AG 2000-BRI | 8 | None | agpi2bri_fax.cfg | agpi2bri_faxa.cfg
AG 2000/400 | 16 | None | agpi2fax.cfg | agpi2faxa.cfg

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.
