Physical description
The NTC314AAE6 MG1010 utility card is a standard card size with a two inch metal faceplate.
The Utility card is inverted to accommodate power connections on the backplane. The
components are placed to left instead of right.
Functional description
The MGU provides connectivity to the three serial ports of the MGC inserted in slot 0 and to
the two serial ports of each call processor card inserted in slots 22 and 23.
The blower module assembly contains the blower control ICs but the Interface card contains
the LED status. The utility card also contains the ring generator functions and the message
waiting voltage supply. The PCB is located on the opposite side of the card, in respect to other
cards, to prevent interference with the power supply connector on the backplane.
A temperature sensor located at the lower front of the card allows the SM bus to poll for ambient
temperature of the air entering the chassis. Faceplate LEDs, for both power supplies, mirror
the power supply LED giving the same display on both the front and rear of the chassis. A dip
switch for setting ringing requirements, as well as message waiting, exists on the card with
settings silk-screened on the PCB for all international settings. The card also contains power
fail transfer circuitry and interfaces to the auxiliary connector located on the I/O panel at the
rear.
