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

—
