Abstract
A media selection device is in functional parallel with an alternate local telephone network and an existing local telephone network. Upon detecting a loss of local power, the device switches to the local exchange network based on the assumption that the local exchange network is operable, despite the loss of local power. While power is supplied to the device, originating calls are transmitted from the telephone to the device and to the alternate network. Incoming calls from the alternate network are transmitted to the device and to the telephone. Alternatively, incoming and outgoing calls are also selectably engageable on the local exchange network without disrupting telephone service on the alternate network. Differences in dial tone indicate which network is currently being used.
