ABSTRACT:
A converted telephone plug inserted into the first jack of a traditional, local telephony network breaks the normal connection to a public switched telephony network (PSTN) and reroutes signals to special telephony equipment for further connection to a modem access network. The advantages are that local analog telephones, can be used as interfaces also against the modem network and that installation becomes easy.
