SECURE YOUR TELEPHONE NETWORK INTERFACE FROM UNAUTHORIZED USE!

WARNING!  Access to the telephone network is possible from the telephone network interface (TNI) device on the outside of your building.

As a result, it is feasible that unauthorized use may occur. To discourage the possibility of such use, and the resulting unauthorized toll charges, we recommend that you secure the TNI device with a padlock. If you have any further questions regarding this warning notice please contact our business office.

Ponderosa Telephone installed a plastic housing called a Telephone network interface (TNI) device on the outside of your building. This outdoor TNI is located where your telephone service enters your premise.
