Verification
The CDM-625 includes many test modes and loopbacks for rapid verification of the correct
functioning of the unit. Of particular note is the IF loopback, which permits you to perform a
quick diagnostic test without having to disturb external cabling. During the loopback, all of the
receive configuration parameters are temporarily changed to match those of the transmit side,
and an internal RF switch connects the modulator output to the demodulator input. When
normal operation is again selected, all of the previous values are restored.

Updating Modem Firmware
Chapter 4. UPDATING FIRMWARE
The CDM-625 stores its firmware internally in flash memory, which simplifies the firmware
updating process without having to open the modem. Firmware downloads are available via the
