The IUC-X9-TXA is a telephone line transmitter which takes in one of a number of standard analog signal. It has a 600 Ohm impedance matched output which can connect directly into a class C telephone line. A frequency signal is sent to the IUC-7X-RXA telephone line receiver where it is converted back to an analog signal. The IUC-7X-RXA also has an impedance matched input to allow direct connection to the phone line. A built in line monitor detects line failures and closes a contact if this happens.
