ELR means that pressing the Recall button earths one of the two incoming
wires.
TBR puts a very short open break on the normally closed (when phone is
in use) circuit. All new push button phones will do a Timed Break
Recall, which if pressed during phone usage will bring on the dialling
tone so that you can make a call with the original call on hold.
Pressing the Recall button again will restore the original call.
Hope this helps.
Regards Mike.
