Functional description 517
— enabling/disabling of individual units or entire card
— programming of loop interface control circuits for administration of
line interface unit operation
— maintenance diagnostics
The microcontroller also controls the front panel LED when the card is
enabled or disabled by instructions from the NT8D01 controller card.
The digital line card contains a microcontroller that controls the internal
operation of the card and the serial card LAN link to the controller card. The
microcontroller controls the following:
•
reporting to the CE CP through the card LAN link:
— card identification (card type, vintage, and serial number)
— firmware version
— self-test status
— programmed configuration status
•
receipt and implementation of card configuration:
— programming of the digital line interfaces
— enabling/disabling of individual units or entire card
— programming of loop interface control circuits for administration of
line interface unit operation
— maintenance diagnostics
