NT8D14 Universal Trunk card
553-3001-211 Standard 3.00 August 2005
Card control functions
Control functions are provided by a microcontroller, a card LAN interface,
and signaling and control circuits on the NT8D14 Universal Trunk card.
Microcontroller
The NT8D14 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 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 through 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
Card LAN interface
Maintenance data is exchanged with the common equipment CPU over a
dedicated asynchronous serial network called the Card LAN link.
Signaling and control
The signaling and control portion of the Universal Trunk card works with the
CPU to operate the card hardware. The card receives messages from the CPU
over a signaling channel in the DS-30X loop and returns status information to
the CPU over the same channel. The signaling and control portion of the card
