== Changing the Line Rate ==

This sets the line rate on your line:

This change is applied the next time you connect (Re-PPP).

[[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 ~~re-negotiate~~ the PPP connection with your router allowing the MTU to be reduced. On TalkTalk connections the MTU is always negotiated as 1492 MTU, you will need to select LCPFix and 1500 MTU to fix this, otherwise the LNS will use 1492 MTU when re-~~negotiating.~~

This is sometimes called 'LCP re-negotiation always'

=== FastTimeout ===

Line 66:

[[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.
