Private ET Networks

By far, the most popular option for ET is for businesses to purchase their own key-system or PBX to provide local telephone access to their employees. This method provides many benefits, including the following:

• No recurring charges—Owning a PBX costs less per month than purchasing Centrex services from the PSTN.

• Control over adds, moves, and changes—There is no need to contact the PSTN carrier to add new lines, move a phone, or change subscriber information.
