Which of the following statements is CORRECT about call rights and user rights on U1900?

Question

Options

• AUser rights are configured during prefix configuration.
• BThe international call right can be used only for configuring the outgoing prefix.
• CThe international call right can be used for configuring prefixes only starting with 900.
• DIf you do not configure the user right when a user is being added, the user right is Normal by

• A
  9% (5)
• B
  75% (41)
• C
  4% (2)
• D
  13% (7)

Explanation

Option B is correct because on the Huawei U1900, call rights (such as internal, local, domestic, and international) are attributes assigned to outgoing prefixes to control which callers can use those routes - the international call right specifically governs outgoing prefix configuration, not incoming or other routing elements.

Why the distractors are wrong:

• A is wrong because user rights (e.g., Normal, Operator, Administrator) are configured during user addition/modification, not during prefix configuration - these are two separate configuration steps.
• C is wrong because the international call right is not restricted to prefixes starting with "900"; it can apply to any outgoing international prefix (e.g., 00, 011) regardless of the digits.
• D is wrong (and also appears truncated) because the default user right when none is configured is not simply "Normal" - failing to configure a user right does not guarantee a safe or predictable default on the U1900.

Memory tip: Think of call rights as "keys for the door" - the outgoing prefix is the door, and the call right level (local, domestic, international) is the key required to open it. User rights are a separate concept about who the person is, not where they can call.
