1.0 Overview
-----------------------------------------------------------------

The MIDAS LCC (Local Communications Controller) is a major 
communications and processing node of the MIDAS hierarchical 
network. It represents the highest point in the structure of
outstation equipment.

The LCC is connected between the MIDAS Subsystem (also known as
the Instation) and the Transponders (TPR) and is located at a 
transmission station, Control Office or RCC building. Within the 
MIDAS network, the LCC is responsible for message assembly, 
routing and control of TPRs. The device is capable of addressing 
up to 32 TPRs.

2.0 LCC Firmware
-----------------------------------------------------------------

The LCC firmware is capable of firmware upgrade via 
specially formatted USB pen drive which is supplied with every 
LCC.

2.1 LCC Firmware Upgrade

There are two types of firmware upgrade:

 - LCC Firmware Update Only (issue_s1497)
 - LCC Full System Update (issue_s1498)

The LCC Firmware Update only updates the LCC firmware and leaves 
the operating system and all system boot files unchanged.

The Full System Update formats and updates the entire LCC 
firmware and operating system.
