Understanding Broadband Line Rate Statistics

Where can I find the line rate for my broadband connection?

How to get the line statistics from a BT Voyager router:

 

If you are currently connected to BT Broadband with your Voyager router click on the following link http://192.168.1.1/infodsl.html

 

The table below shows the line rate for each BT Broadband Option.

 

Product

Downstream

Upstream

Option 1 (1 Mb)

Up to 1024 Kbps

Up to 128 Kbps

Option 2 (3 Mb)

Up to 3072 Kbps

Up to 384 Kbps

Option 3 (7.6 Mb)

Up to 7616 Kbps

Up to 672 Kbps

 

Up to 24Mb BT Broadband is different to previous broadband technology in Ireland in that it is 'rate-adaptive'. Using this new technology, the service will automatically provide you with the fastest broadband speed your phone line can physically support, up to a maximum of 24Mb (or 24 megabits per second).


24Mb is the maximum speed achievable over a line of average length from the exchange - for longer lines, the maximum speed achievable will be less. Speed will also vary throughout the day depending on how busy the Internet is, often decreasing significantly during the daily peak period (6pm - 9pm).

 

So Up to 24Mb customers should expect to get a downstream line rate some where between 3072Kbps and a maximum of 24576Kbps.

 

However, if you are subscribed to say BT Broadband Option 1 then your line should always synchronise at 1Mb (i.e. 1024Kbps). If the downstream broadband line rate is less than 1024Kbps (for Option 1) then this would indicate that some telephony device or cable connected to your line is causing interference and reducing the speed of your broadband connection.

 

The most common cause of a poor broadband service is the use of poor quality telephone extension cables. This is because they are more prone to electrical interference, which causes BT Broadband to reduce data speeds to compensate. Avoid using extension cables or extension sockets.

 

You should also ensure that every phone socket in use in your premises has a microfilter attached. If you have already done this and the broadband line rate is less than it should be then one of these filters may be causing a problem. Plug your broadband router directly into your master telephone socket with no other phones or filters attached to ANY other socket. Check the line rate again, if it has changed then one of your microfilters may be faulty.

 

Up to 24Mb customers should obviously also adhere to the tips above regarding filters, extension cables etc. to get the maximum possible speed your line is capable of achieving.
