im working on bringin up a 15454 dwdm chassis with OPT-PRE, OPT-BST, OSCM, 40-MUX-C, 40-DMX-C but having a bit of trouble.
I read in the procedure guide that a large part of the config is to be done via CTP and uploaded to the ONS box.
Is CTP absolutely necessary for bring up a DWDM box ?
Can a DWDM chassis be setup without CTP ?
Is CTP available for download from cisco.com ?
When designing and turning up laser-launched optical links, it's always a good idea to double check your loss and power levels. Start with a paper-based calculation (a good overview is at http://www.cisco.com/en/US/products/hw/optical/ps2006/products_tech_note09186a00800e6eeb.shtml). that should put you in the design range "ballpark", allowing you to prperly choose and specify the type of optics (PPMs in the case of 15454's) to use. Once you are in the field, add to that work an actual optical power measurement from a test set. Use that measured value to set your provisioned launch power levels. Finally, fine tune the values using the Provisioning and Span Loss (Maintenance > DWDM > WDM Span Check) tools in CTC.
