Installation and Connectability
To provide felxibility and potential for growth, telephones are easily and economically connected to any telephone network by standard wiring and parts. Voice quality is unaffected when phones are connected within 15,000 feet (~4,600 meters) of a main telephone switch accepting single line telephones. Meeting safety standards may require use of special wiring conduits or other considerations. The phone can be factory set for either tone or pulse operation.
