What is overlap vs en-bloc dialing?

• A. Overlap sends digits after a delay; en-bloc sends digits immediately.
• B. Overlap sends the full number; en-bloc sends digits as dialed.
• C. Overlap uses translation patterns; en-bloc uses route patterns.
• D. Overlap sends digits as dialed; en-bloc sends the full number once dialed.

Answer: (D)

Overlap dialing transmits digits to the network as you dial them, so routing decisions can begin with partial digits. En-bloc dialing waits until you finish dialing (or a timeout occurs) and then sends the entire number as a single block. The correct description matches this: overlap sends digits as dialed, en-bloc sends the full number once dialed. The other wordings mix up the timing or introduce unrelated concepts like translation vs route patterns.
