5ess matters not to a line side.. it needs to be clear channel, ie it does not term at the central office

ground start on a line side? line side t's program as analog phones and are usually used on the far end as trunks in a key system or pbx.. you need a line side on the far end. i have several here, the coding is on the serial interface not in the switch... mine are loop start since i can't make analog stations ground start..

you can have a channel bank on the far end, that gives you analog dialtone per channel.. i haven't seen one in years but they were common when extending to older equiptment..

I should say can be configed for grnd or loop, which is a simulation, and maybe meaningless knowledge.
A bit = Tip ground
0 grounded 1 not grounded
B bit ringing 0 on 1 off

receive A bit = loop 0 open 1 closed
B bit = ring ground 0 grounded 1 not grounded


from terminal equiptment, channel is seized when TE simulates grnd on the ring lead toward the lineside card causeing B to toggle from 1 to 0 on an outgoing call. etc, etc, blah, blah, blah

So is there a way i can see how they are setup
right now they are being used as 500 sets for a periophonics IVR but the customer wants to use them for a dialogic board

Pull the card and look at the jumpers. At least that's how I do it. Or you get lucky and the slot next to it is open and you can see them with a flashlight.
