__NOTOC__ A line dropping sync intermittently will need investigation.▼ <center> ~~==Examples==~~ ▲A line dropping ~~sync~~ intermittently will need investigation. ~~Here are some examples of lines that are dropping:~~ {\| class="wikitable" \|- \| style="vertical-align:top; border-style: solid; border-width: 5px; border-color: #0095FF;" \| [[File:1.svg\|100px\|left\|link=ADSL_Checks]] == [[ADSL Checks\|1. Standard Checks]] == First of all, go through the standard checks, we should then be confident that the cause of the dropping is not on the customer side. \|- \| style="vertical-align:top; border-style: solid; border-width: 5px; border-color: #0095FF;" \| [[File:2.svg\|100px\|left\|link=Dropping_DSL_CQM]] == [[Dropping DSL CQM\|2. Check CQM Graph]] == ~~===Lots of Drops===~~ You may be able to get some clues from the graphs. Find out more here. ~~[[File:Cqm-dropping2.png]]~~ \|- This line does have a fault. It is dropping sync throughout the day. In this type of case, go through the usual checks, and AAISP will report a fault, which will probably need a BT SFI Engineer to atend site. \|style="vertical-align:top; border-style: solid; border-width: 5px; border-color: #0095FF;" \| [[File:3.svg\|100px\|left\|link=Dropping_ADSL_Diagnostics]] ==~~=Only~~ [[Dropping ~~during~~ADSL ~~the~~Diagnostics\|3. Use Diagnostic Tools]] ~~day=~~== You can run tests on the line to see if they indicate a fault. ~~[[File:CQM4.png]]~~ \|- \| style="vertical-align:top; border-style: solid; border-width: 5px; border-color: #0095FF;" \| [[File:4.svg\|100px\|left]] == 4. Contact Support == Contact support, they will run further tests and will report a fault - usually a dropping connection will require us to arrange a BT Openreach engineer to attend site. \|} </center> (Probably not an ADSL Fault.) If a line is dropping during the day, and maybe just Monday to Friday, then it's probably not going to be an upstream problem. This could be caused by interference of bad wing on site. Check things like the phone line and extensions. Put the router in master socket and to unplug all other phones. Maybe change filter.
