A PIIC interface has been selected and the clock is set to lock to an
External Clock (as with G.703 or other Synchronous PIIC cards), however
the clock signal does not match the expected clock rate.
A PIIC interface has been selected and the clock is set to lock to an
External Clock (as with G.703 or other Synchronous PIIC cards), however
no clock signal is detected.

is missing or corrupt.
The modem's internal 250MHz clock is out of range or has failed.
The modem's internal 900MHz clock is out of range or has failed.
The modem has been set to run in MEO mode and the communication
between the remote Tx/Rx modem and remote Rx demod is timing out or is
getting corrupt / unexpected.
The modem has been set to run in MEO mode and the communication
between the remote Tx/Rx modem and hub / gateway Tx/Rx modem is
timing out or is getting a corrupt / unexpected response.
The modem has been set to run in MEO mode and the communication
between the remote Tx/Rx modem and the ACU is timing out or is getting a
corrupt / unexpected response.
One or more of the Modem's Gig-E Ethernet ports (J5, J6, J7) is enabled
but the modem does not detect any connection to another device (switch /
router / PC etc.).
The modem's internal DAC clock out of range or has failed
