Abstract
A modem/telephone interconnect for sharing a telephone line or communication channel between a modem and a telephone or other communication device. The interconnect provides access to the telephone line by both devices but normally prevents each device from interrupting or interfering with the operation of the other. The telephone can be used to monitor data transfer by the modem without the possibility of interfering with the data signals or quiet times.
