Broadband Guides » How Dynamic Line Management (DLM) Works

Dynamic Line Management (DLM) is a process which continously monitors your line to ensure that a stable connection is being maintained.

This works by data being sent to the DSLAM every time you connect to the Internet, including line data and any errors on the phone line.

The information is collated by the Data Collector which in turn sends it to the Dynamic Line Management system.

Should the DLM detect an issue on the line it will adjust SNR and Interleaving settings or decrease your connection (sychronisation) speed to a level which will provide you with a stable connection.

If on the contrary your connection proves stable at a higher sychronisation speed, DLM will increase your profile to operate at this level.

It's important to note that your connection must remained sychronised at the higher rate for 3 days before DLM will update your BRAS profile.

If any changes are made, DLM sends the information via the flow stream to NCAS. NCAS then reports to the DSLAM which then makes the relevant changes to the individual users line card.
