reporting to the CE CPU 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 CODECs
— enabling/disabling of individual units or entire card
— programming of input/output interface control circuits for
administration of line interface unit operation
— enabling/disabling of an interrupted dial tone to indicate call waiting
— maintenance diagnostics
— transmission loss levels
