How telecom companies appoint DPO and Data Processor

1) it is mandatory to appoint a DPO
2) it is mandatory to appoint a "Data Processor"

Answer:
1) Usually telecom companies need to appoint a DPO because they are processing personal and traffic data of their customers. Moreover you may perform network surveillance as well to monitor the traffic and parameters on your network as well as to detect unusual traffic thus you would be monitoring the behavior of your customers.
2) Not sure what you mean about “appointing a Data Processor”. The EU GDPR defines the processor as “a natural or legal person, public authority, agency or other body which processes personal data on behalf of the controller; “. So processors are not appointed but rated they contracted by controller to process data on their behalf.
