What is Grade of Service (GOS)?
Multiple Choice Options
- A✓ Correct Option
Call failure rate
- B
Transmission quality
- C
Signal delay measure
- D
All of the above
Detailed Technical Solution & Explanation
In telecommunications and traffic engineering (Erlang models), Grade of Service (GOS) is defined as the probability of a call being blocked, lost, or delayed due to network congestion (call failure rate / blocking probability ).
Option Analysis:
•
Option A (Call failure rate): Correct. GOS quantifies the proportion of calls that fail to connect or are blocked.
•
Option B (Transmission quality): Measured by BER or SNR, not GOS.
•
Option C (Signal delay measure): Measured by latency / jitter.
•
Option D (All of the above): Incorrect.
