发明名称 Relay circuit for telephone interface
摘要 A reduced number of relays are used in a voice/data/fax modem system. This reduced relay design eliminates at least one relay required in prior art systems thereby reducing the amount of geography used in producing the resultant device. This saves space, reduces costs, and provides a more reliable device.
