Functional description 499
— programming of input/output interface control circuits for
administration of trunk interface unit operation
— maintenance diagnostics
— transmission pad settings
The universal trunk 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 CPU via 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 via the card LAN link:
— programming of the Codecs
— enabling/disabling of individual units or entire card
— programming of input/output interface control circuits for
administration of trunk interface unit operation
— maintenance diagnostics
— transmission pad settings
The NT8D14 Universal Trunk Card contains a microcontroller that controls
