customer can't create WDM trail using trail method

Publication Date:  2012-07-25 Views:  77 Downloads:  0
Issue Description
    Customer complaint they can’t use trail method configure WDM traffic on test bed, he checked the WDM trail ,WDM discrete trail and ASON trail, there are no any trail display, the net work just have 3 NE using OSN 6800 V1R4C04SPC800

Alarm Information
Handling Process
Checking all the logical and physical fiber, make sure all the data is right
Checking board cross connection site by site , make sure the related wavelength is free
Checking single station cross connection site by site , there are some intelligent cross connection existing on one site, and try to delete it, it can’t
this is intelligent traffic , so if you want delete it ,we should change the traffic attribution to traditional traffic.
Find ASON configuration item in site function tree ,choose WDM ASON signaling maintenance item, choose the all the related traffic ,then degrade the traffic to traditional traffic. Check the traffic attribution ,all the related traffic change to “create manually”. Then delete this traffic.
Try to use trail way create the traffic again, then operation is successful.
Root Cause
If we can’t use trail configure WDM traffic ,we should analyze this reason :
  1. all the physical and logical fiber connection is right according to the design
  2. the related wavelength is free ,not be occupied by board cross connection
  3. there are no any discrete connection in NE for related wavelength.

    If engineer want to delete ASON traffic, it’s better use trail way to manage and delete it ,if there are some intelligent traffic existing ,we can’t delete it directly , we should degrade it and then delete it.
