DRAFT

If any significant change in signal level results from any

component being replaced in the RX or TX signal flow

paths, it would be identified by re–running the RX and TX

calibration audit command.

NOTE

When the CIO is replaced, the C–CCP shelf remains powered up. The

BBX2 boards may need to be removed, then re–installed into their

original slots, and re–downloaded (code and BLO data). RX and TX

calibration audits should then be performed.
