372 NT6D70 SILC Line card
Micro Controller Unit (MCU)
The Micro Controller Unit (MCU) coordinates and controls the operation
of the SILC. It has internal memory, a reset and sanity timer, and a serial
control interface.
The memory consists of 32 K of EPROM which contains the SILC
operating program and 8 K of RAM used to store 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 used by the MPU to
communicate with the S/T transceivers.

IPE interface logic
The IPE interface logic consists of a Card-LAN interface, an IPE bus
interface, a maintenance signaling channel interface, a digital pad, and a
clock controller and converter.
