386 NT6D71 UILC line card
The memory consists of 32 K of EPROM that contains the UILC operating
program and 8 K of RAM that stores interface selection and other functions
connected with call activities.
The reset and sanity timer logic resets the MCU.
The serial control interface is an IPE bus that communicates with the U
transceivers.
The MCU coordinates and controls the operation of the UILC. It has internal
memory, a reset and sanity timer, a serial control interface, a maintenance
signaling channel, and a digital pad.

IPE interface logic
The IPE interface logic consists of a Card-LAN interface, a IPE bus
interface, a maintenance signaling channel interface, a digital pad, and a
clock converter.
The Card-LAN interface is used for routine card maintenance, which
includes polling the line cards to find in which card slot the UILC is installed.
It also queries the status and identification of the card and reports the
configuration data and firmware version of the card.
