■ Voice Subscriber-line view
Description This command is used only for 2-wire loop trunk subscriber-line FXO, and it can only
perform configuration to the first voice subscriber-line on the voice card.
This command is used to set the frequency spectrum characteristic used by the router
to detect the existence of the busy tone.
If successful, the configuration will be effective for all the voice subscriber-lines of the
voice card.
When this subscriber-line is connected to a common user line of a program-controlled
switch, if the user on the switch side hooks on first, only by detecting the busy tone
can the router know the user on-hooking operation. Since different switches execute
different prompt tone schemes, there exist different frequency spectrum
characteristics.
