NETWORK BREAKER

摘要

A converted telephone plug (70) inserted into the first jack (60) of a traditional, local telephony network (10) breaks the normal connection to a public switched telephony network (PSTN)(30) and reroutes signals to special telephony equipment (50) for further connection to a modern access network (20). The advantages are that local analog telephones (42), (44) can be used as interfaces also against the modern network and that installation becomes easy.
