Answer 1

The correct answer is d) All of the above because DID is a feature offered by service providers, it allows direct calls to a PBX station without an auto attendant, and the DID number can differ from the local extension number.

Step-by-step explanation:

Direct Inward Dialing (DID) is a service provided by telephone companies that offers several key features for businesses, particularly those using a Private Branch Exchange (PBX) system. Answering the student's question, d) All of the above is the correct choice. Direct Inward Dialing is indeed a feature offered by telephone service providers. It facilitates the process of calling directly to a PBX station without the necessity of navigating through an auto attendant, thus streamlining communication. Additionally, it is accurate that a station's DID number can be entirely unrelated to its local extension number, providing further flexibility within a business's telephone system.
