The cubic-kilometer neutrino telescope, consisting of large-scale 3D-arrays of photomultiplier tubes (PMTs) currently under construction on the Mediterannean seabed, relies on accurate calibration procedures in order to answer its science goals. These proceedings present an overview of a novel gain calibration method based on highly compressed PMT hit information. In particular, it is shown that the PMT gains can be tuned to within 2% of the nominal value, based on the measured time-over-threshold.
