global trunk quality的意思|示意

Global trunk quality (GTQ) refers to the quality of the trunk circuits used to carry voice, data and multimedia traffic within a telecom network. It is one of the major components of network performance and reliability.

GTQ is typically measured in terms of latency, jitter, packet loss, and call setup success rate. Latency is the delay experienced between when a packet is sent and received. Jitter is changes in latency experienced over time, while packet loss is the number of packets that do not make it to their destination. The call setup success rate, meanwhile, refers to the success rate of establishing calls.

GTQ affects the overall user experience of a telecom network, as users engage in tasks such as making and receiving calls, streaming multimedia content and using mobile internet services. Poor GTQ can lead to dropped calls, poor sound quality and slow internet speeds, all of which can be frustrating for end-users.

To ensure good GTQ, telecom operators need to invest in reliable and quality trunk circuits. These circuits should be regularly monitored for performance and reliability, and any issues should be addressed quickly to maintain network performance. Additionally, regular maintenance should be performed to ensure that circuits remain in peak condition.
