Meaning of NSTR
In a railway signaling system, a signaller token is a physical device that represents the authority to proceed. It is used to control the movement of trains on a section of track. When a signaller grants permission to a train to proceed, they issue a signaller token to the train's crew.
NSTR indicates that there is no physical signaller token being used in the signaling system. Instead, the authority to proceed is transmitted electronically from the signaller to the train. This can be done via various technologies, such as radio or data links.
Advantages of NSTR
- Elimination of physical tokens: NSTR eliminates the need for physical signaller tokens, which can be lost or stolen.
- Increased safety: NSTR enhances safety by preventing trains from proceeding without proper authorization.
- Improved efficiency: NSTR streamlines the process of granting and revoking authority, leading to increased efficiency in train operations.
- Reduced costs: NSTR can reduce the costs associated with the production, distribution, and maintenance of physical signaller tokens.
Essential Questions and Answers on No Signaller Token Remote in "MISCELLANEOUS»UNFILED"
What does NSTR stand for?
NSTR stands for No Signaller Token Remote. It is a state in a telephony system where a remote station does not have a valid signaller token.
What is a signaller token?
A signaller token is a unique identifier that is assigned to a remote station. It is used to authenticate the remote station and to allow it to communicate with the telephony system.
What causes a remote station to lose its signaller token?
A remote station can lose its signaller token for a variety of reasons, including:
- The remote station is restarted.
- The telephony system is restarted.
- There is a network error.
- The remote station's configuration is changed.
What are the consequences of a remote station losing its signaller token?
If a remote station loses its signaller token, it will not be able to communicate with the telephony system. This can result in the loss of service for the remote station and any devices that are connected to it.
How can I resolve an NSTR issue?
To resolve an NSTR issue, you can try the following steps:
- Restart the remote station.
- Restart the telephony system.
- Check for network errors.
- Verify the remote station's configuration.
Final Words: NSTR (No Signaller Token Remote) is a term that signifies the absence of physical signaller tokens in a railway signaling system. NSTR systems utilize electronic means to transmit authority to proceed, resulting in improved safety, efficiency, and cost-effectiveness.
