Introduction
CDM-760 Advanced High-Speed Trunking Modem
During IF loopback, all of the receive configuration parameters are temporarily changed to
match those of the transmit side, and an internal IF switch connects the modulator output to
the demodulator input. When normal operation is again selected, all of the previous values are
restored.
