In generic terms, yes, FTTP begins its journey from the 'Head End' in the parent Exchange (this may not be the same Exchange your phone line is provisioned from, it may well 'bounce' off another Exchange known as a 'Parent & Child' set up).
From there the remit is to follow the same ducts/poles as the copper cable does, but there are scenario's where this can and does change such as 'civils avoidance, high cost, traffic management etc'.
Depending on the existing network capacity and the cost of deploying a new fibre spine cable, sometimes we use a SHE (Subtended Head End) design that utilises the spare cables going into the existing FTTC Cabinet.
I'm not sure about DLM on FTTP, but can't for the life in me see why it would be required ??.
Sorry for quick answers ... busy as.
