| Description | The DWDM channel bitmap that indicates those channels that
are included or excluded (depending on the value of
coIfDwdmChannelBitmapLogic) from the DWDM channel group.
If a frequency is included in a DWDM channel group, this does
not necessarily indicate that there is a signal present at that
frequency. It indicates that if a signal is present at that
frequency, then that signal is included in this DWDM channel
group.
Bit zero of octet one corresponds to the lowest channel
(representing the frequency identified by
coIfDwdmChannelGroupMinFrequency), bit one of octet one
corresponds to the lowest plus one channel (representing
the frequency obtained by adding the values of
coIfDwdmChannelGroupMinFrequency and
coIfDwdmChannelGroupSpacing), and so on.
When the value of coIfDwdmChannelBitmapLogic is 'carried',
then channels included in the channel group will have the
corresponding bit set to one in the bitmap. Bits that are set
to zero represent channels that are excluded from the channel
group. Channels that are not represented in the bitmap are
also excluded from the channel group.
When the value of coIfDwdmChannelBitmapLogic is 'blocked',
then channels excluded from the channel group will have the
corresponding bit set to one in the bitmap. Bits that are set
to zero represent channels that are included in the channel
group. Channels that are not represented in the bitmap are
also included in the channel group. |
