[Asterisk-Users] MFE for TEI=76

Hi Jens,

"MFE for TEI=76" means that a layer 2 p2p connection has been
established between your * and your telco's switch. This is a 
good thing! :)
It looks like your telco is pulling down layer 2 when the line
is idle (probably also layer 1 for power saving). Do you see
a lot of "card X span Y state FZ (A_ST_RD_STA = 0x1Z) messages
in dmesg? Those indicate state changes on layer 1.

I am currently cleaning up some things, so these messages will
only appear if you have "bri intense debug span Y" enabled.

best regards
