Description Tularosa Basin Telephone Company (“TBTC”) was established in 1996 after US West decided to sell off six exchanges throughout the state of New Mexico. Carrizozo, Cloudcroft and Tularosa were among those exchanges. Four telephone companies banded together to found TBTC. The four companies are: Dell City Telephone Cooperative of Dell City, Texas; Roosevelt County Cooperative of Portales, New Mexico; Ponderosa Telephone Inc. of O’Neals, California and Wagner Telecommunications of Colorado Springs, Colorado.
