# Programming R2 Trunks

The R2 trunks are supported only on an EX Controller. You can program an R2 trunk by executing the configuration files available in the Gateway Configuration Scripts form.

NOTE: You can also program the R2 trunks manually through the EX Controller Web GUI. For more information on how to program, see Appendix B Programming an R2 Trunk in the Installation and Administration Guide for EX Controller document.
