Well, I am confused. The only types of trunks that I know about where you can "dial in and reach extensions on the pbx" are either:
DIDs or
Tie Lines.
Every Analog DID I ever dealt with was Loop and then either Wink, Immediate or Delay Dial - but NOT Ground Start.
Tie Lines were usually E&M, either 2 wire or 4 Wire and there's no way you could mistake an E&M trunk for anything else. There were non E&M tie lines that we saw very, very rarely, but they were loop too.
So what is this trunk supposed to do? How does it work? You ground one side of the circuit and then you get dial tone FROM THE PBX and then you dial an extension in the PBX?
I'm a little confused.
But I find that happening more and more as I get older and less useful.
