Is the following description correct? PVM manages and controls the business single board in the UA5000 chassis, and can also send tones and collect numbers to realize the V5 protocol and H248/MGCP…

• ATrue
• BFalse

Explanation

Option A is correct because the PVM (Peripheral Voice Module) in the UA5000 chassis is specifically designed to handle both control-plane and signaling functions on a single board. It manages business logic, generates and sends tones (such as dial tone and ring tone), and performs digit collection (DTMF), which are all prerequisites for processing call signaling. The PVM supports both the V5 protocol (used for traditional PSTN/ISDN access between access networks and local exchanges) and H.248/MGCP (used in softswitch/NGN architectures for media gateway control), making it a versatile voice processing board for mixed-network environments.

Option B is incorrect simply because the description accurately reflects the documented capabilities of the PVM board - there is no functional element in the description that is wrong or exaggerated.

Memory tip: Think of PVM as a "Voice Swiss Army Knife" - it handles the Protocols (V5, H.248/MGCP), the Voice tones, and Manages the board, all in one. If a question lists multiple PVM functions together, they're likely all correct since the PVM is designed to consolidate these voice-layer responsibilities on a single board.
