== Changing the Line Rate ==
This sets the line rate on your line:<br />
This change is applied the next time you connect (Re-PPP).

== Stability Options ==
Forces an MTU regardless of what is negotiated by your router.
'''More Info:''' MTU is negotiated upon connection. We usually like 1500 MTU, however, there can be situations where forcing 1492 MTU is required. For example, if your router negotiated 1500 MTU initially but you make a connection to a server that
=== TCPFix ===
[[File:LineOptionsLCPFix.png|none|frame|Re-negotiates PPP after acquiring the connection from BT, who may provide 1500 MTU when it should be 1492 MTU.]]
'''More Info:''' During the PPP connection when your router initially syncs up and logs in to us, the PPP connection is passed via BT. Sometimes BT can change the MTU. With this option we will accept the PPP connection from BT, but will then
=== FastTimeout ===
[[File:LineOptionsRate100.png|none|frame|Uses an LCP Echo timeout of 10 seconds rather than 60 seconds before entering the LostCarrier state.]]
'''More Info:''' LCP echoes usually stop responding if the line has gone down. Our LCP monitoring, which produces the graphs, will drop the line if there are no replies after 60 seconds. When [[bonding]] or used in a fall-back setup, having a faster timeout is useful in order to fall-back quicker.
==LNS reset==
From time to time there are upgrades to the LNSs. This is usually to add new features, or fix bugs.
Upgrading an LNS is very quick, and it is only off line for under a second. However, it does mean stopping all of the sessions on the LNS, which means we will force your DSL service to reconnect. You can set the preferred time for the reconnect to happen, the default is 1AM.
{{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}}
