This article is rather technical and covers the way we connect to BT for broadband links.
The LNS handles authentication (logging in using your username and password) and routing of your IP addresses to you. It handles the negotiation of the link with your equipment and establishes a session.

==Multiple LNS links to BT, TT and mobile==
We operate multiple LNSs connected to multiple links in to carriers. This is partly for redundancy (if one of the LNSs or links break) and partly for load (to handle
We currently have a mix FireBrick FB6000 and FireBrick FB9000 LNSs and operate them as separate 'pools':
Normally we run with n-1 live LNSs and so this leaves one as a backup in case of failure.▼
*23 FB6000: A-W.Gormless
*3 FB9000: X-Z.Witless
The LNSs named 'Witless' handle faster FTTP and G.Fast circuits, whilst the 'Gormless' LNS handle the rest, including mobile data SIMs.
The LNS named 'Doubtless' and 'B.Doubtless' are test LNSs.
==Maintenance and LNS switches==
==Choosing the Time==
CityFibre connections tend to get moved at 4AM.
You can set the preferred time for the reconnect to happen to your own line(s), the default is 1AM. There is a setting on the control pages for this:▼
▲For other connection types: You can set the preferred time for the reconnect to happen to your own line(s), the default is 1AM. There is a setting on the control pages for this:
{{CPbox|#Click on the line you want to view
#Click on your login (e.g. abc@a)
#Set the 'LNS reset'. You can choose a time between 1AM and 6AM
==Test LNS==
Usually this creates a good graph for the previous day. However, in some cases the previous day on one of the LNSs may have been deleted before archive. In some cases the two LNS may operate on a different scale and so the combined graph looks messy and confusing. In some cases we change the graph format slightly and this can also lead to a messy graph.
