Method and arrangement in a telecommunication system for estimating frequency dependent resistance |
| 摘要 |
Method and arrangement in a telecommunication system for estimating frequency dependent resistance of a transmission line. Insertion loss per length unit of the transmission line at a first frequency is determined. Thereupon a first resistance per length unit based on the determined insertion loss per length unit of the transmission line is calculated. Effective resistance per length unit at a second frequency based on the calculated first resistance is calculated. The calculated effective resistance could be used when estimating the insertion loss for the second frequency and all frequencies of interest. |

1. A method in a telecommunication system comprising a digital subscriber line access multiplexer (DSLAM) or a server connected to the DSLAM, for estimating frequency dependent resistance of a transmission line, comprising the steps of:
determining, by the DSLAM or the server, insertion loss per length unit of the transmission line at a first frequency, calculating, by the DSLAM or the server, a first resistance per length unit based on the determined insertion loss per length unit of the transmission line; and calculating, by the DSLAM or the server, effective resistance per length unit at a second frequency based on the calculated first resistance. |
