This table provides a quick summary of the state of the Wavelength Tracker functionality within the WTOCM. The summary attributes are octet strings. As an example, the following 6 octets are returned in summary MIB attribute tnChanInfoSummaryExpectedWKMaskIn: 00000100 00000000 00001000 01000010 00000000 11000000 | | | | | | | | 60 55 52 45 40 35 30 19 Each bit represents an ITU channel. The ITU channel numbers decrement from the MSB of the first octet. In the above data, there are expected wave keys on ITU channels 55, 40, 35, 30, 20, 19. The remaining ITU channels have no expected wave keys.
