Explanation

ASI (Analog Station Interface) is specifically designed to connect analog terminal devices - traditional analog phones and fax machines - to the system. The name itself encodes its function: it provides an analog station interface and nothing else, making it the board that exclusively supports analog terminal access.

Why the distractors are wrong:

• CVP (Computer Voice Processing) handles voice processing functions like IVR, voicemail, or automated attendant - not terminal connectivity.
• OSU (Office System Unit) provides connectivity for digital or hybrid terminal types, not purely analog.
• MTU (Multi-Trunk Unit) interfaces with trunk lines (connecting to the PSTN or other PBX systems), not station/terminal devices at all.

Memory tip: Focus on the word Analog Station Interface - "station" in telecom means a terminal endpoint (a phone), and "analog" tells you the signal type. When you see a board name that spells out exactly what it does (analog + station), that's your answer for "analog terminal only" questions.
