This session introduces commands to run or view line diagnosis as below:
● SELT: Single Ended Loop Test
● DELT: Dual Ended Loop Test
SELT and DELT achieve a goal which reduces time and effort to deploy a new ADSL line, as well as increasing the efficiency of post-install troubleshooting and maintenance. More information is available via DELT diagnose compares with SELT:
● Date Rate (up/down)
● Loop Attenation (up/down)
● SNR (up/down)
● Noise (up/down)
