SIG-00-07-11                                                                                                             SEPTEMBER 2012 (REVISED OCTOBER 2019) 

Version No.: B.2 

TERM 

DESCRIPTION 

SIN 

Site Identification Number. The 12-digit ATCS address for the VIU equipment, entered 

via   the Web interface and stored in the ECD. The SIN has the form 

7.RRR.LLL.GGG.SS stored in binary  coded decimal, with each digit in one nibble. 

The digit 0 is represented by “A” and 0 is used as a null byte. 

SMA 

Sub-Miniature version A. 

TCP/IP 

Network 

Transmission  Control  Protocol / Internet  Protocol. The suite of 

communications 

protocols

 used to connect 

hosts

 on the 

Internet

. TCP/IP uses several 

protocols

, the 

two main ones being 

TCP

 and 

IP

. TCP/IP is built into the 

UNIX

 

operating system

 and 

is used by the Internet, making it the 

de facto standard

  for transmitting 

data

  over 

networks

. 

TMC 

Train Management Computer.   The CBTC Computer on board a locomotive that 

interprets messages from the WIU and controls the locomotive operations 

accordingly.  

TRM 

Transmission Radio Modem 

TSR 

Temporary Speed Restriction 

UCN 

Unique Check Number. A 32-bit CRC calculated over the MCF, SIN and vital 

configuration parameters. Used to verify that the configuration is correct. It is stored in 

the ECD to detect file corruption.  

UDP 

User Datagram Protocol. One of the core protocols of the Internet protocol suite. 

Using UDP, programs on networked computers can send short messages sometimes 

known as 

datagrams

 (using Datagram Sockets) to one another. 

UNS 

Unified Numbering System. 

USB 

Universal Serial Bus. A serial bus standard to interface devices. USB was designed to 

allow many peripherals to be connected using a single standardized interface socket 

and to improve the plug-and-play capabilities by allowing devices to be connected 

and disconnected without rebooting the computer (hot swapping). Other convenient 

features include providing power to low-consumption devices without the need for an 

external power supply and allowing many devices to be used without requiring 

manufacturer specific, individual device drivers to be installed. 

UTC 

Coordinated Universal Time. 

VIU 

Vital Interface Unit. A device that monitors switch positions and signal aspects and 

then generates vital status messages reflecting the current state of the monitored 

equipment. 

VLAN 

Virtual Local Area Network  

VPF 

Vital Parallel Flashing (VPF) input circuit. The VIU Master I/O circuit with 10 vital 

inputs that runs appliance model logic and detects steady and flashing inputs. 

Identical Slave circuits provide10 additional vital inputs with similar functionality .
