Possible ZTP solutions for BAN
Deployment Example
Theory
Automated subscriber and service provisioning system (SSPS)
Subscribers and services are created with the bare minimum human intervention
Practice
Largely automated SSPS with human intervention required

Issues with ZTP on DSL (PANS)Issues with ZTP on DSL (PANS)
Subscriber line patching and qualification between MDF and DSLAM is largely a manual process
DSLAM and ATM (if present) may need to be provisioned for each subscriber
Subscriber self installation not always successful
Truck rolls are a necessity for installations where• New copper runs are required• POTS splitter installation• CPE installation failure
