Table 29: DWDM Channel Numbers

Page 280
• This command configures the Dense Wavelength Division Multiplexing (DWDM) ITU channel
at which a tunable MDA optical interface will be configured to operate. It is expressed in a form
that is derived from the laser's operational frequency. For example 193.40 THz corresponds to
DWDM ITU channel 34 in the 100 GHz grid and 193.45 THz corresponds to DWDM ITU
channel 345 in the 50 GHz grid.Provisioning rules:The provisioned MDA type must have
DWDM tunable optics (m1-10gb-dwdm-tun)
• The 'dwdm channel' must set to a non zero value before the port is set to 'no shutdown'
• The port must be 'shutdown' before changing the dwdm channel.
• The port must be a physical port to set the dwdm channel
