DSL Status values

[fayzanrehman]

Is there any documentation to describe what the expect "DSL router" values should be for my router, if I have a "normal" connection?  I suspect that these values may be quite high, and may indicate there may be problems?

• Upstream Loop Attenuation of 45.3 db?
• Upstream FEC Corrections 22853273
• Upstream CRC error 24

Hi @fayzanrehman!

I've found another forum here which refers to what is considered good DSL line attenuation. I hope this helps.

We'd also be happy to take a further look at your line and router set up with you. As we're unable to discuss account information over the forum, please contact our Social Media team to get started with this 🙂

@beth The Vodafone Customer Services team give me a different answer every time I call.  I want to know from the DSL values, whether they might indicate an issue?  I can never get a straight answer.

Depending on the  person I get responses such as:

There's a fault on the line.

or There's no fault on the line.

There's an amber warning on the connection at the cabinet.

My internal Wifi setup is somehow the cause of the fault on the external line.

There's contention at the cabinet that is the fault of OpenReach/Vodafone

Its the fault of Openreach, or maybe the Vodafone servers for dropped connections or poor upload speeds.

The router tells me the external speed to the house, yet Customer Services want me to continuously run more internal speed tests, as if that can be better than the known external speeds

Hi @fayzanrehman, have you contacted our team on Social Media? The best way to check if there is a fault on the line or any issue is to run some tests. 

We know that you've previously contacted our customer service teams, however, we would recommend that you speak to our broadband specialists over Facebook or Twitter so we can help 🙂

@MarkD  Is that a "no" answer to my initial post question, that there is no available guidance as to what the DSL values mean and no guidance as to whether they may indicate potential issues?

@fayzanrehman Hi, we'd need to take a closer look into your line and find out what may be causing any issues for you. The values you're seeing wouldn't be an indication for us that there's an known issue so we'd need to run further checks on your line. If you haven't already, please do drop us a message on social media and we'll be able to test this out for you and can raise this to our Engineers if needed.

You can include your Community username along with a link to your post from here - you then won't need to write out your query again when messaging us.

Upstream Loop Attenuation of 45.3 db : Is not brilliant but it's normally good enough that an ISP is not going to intervene.

Upstream FEC Corrections 22853273 : This is the number of times errors have been corrected without the need for any retransmission of data - no matter how bad this looks it's not an issue, this is the VDSL protocols doing what they are designed to do!

Upstream CRC error 24 : This is the bad stuff, it's the number of times that the original data could not be reconstructed, depending on the type of data meaning that a re-transmission was probably necessary!  And 24/22853272 aint bad at all!

*Its rather a case of being worried by unexplained info, rather than that info being bad!
