TDE100 Station card Port ID

[brotech]

Working on a TDE100, and it appears all the ports are full. I would like to do an port inventory by determining the port on the Station Card that each phone is connected to. There must be some feature code that is used for this...Similar to the way you do it on a Norstar by doing Feature *0, press intercom key and then the # key.
Can someone tell me what it is?? Thanks

if you look at extension settings, it will show fault if no phone is connected. this will not show slt's in use
