COI(8) U10 ETU Lot 192A

The unit came with three cables punched down to 66 blocks and I've connected them to the right side of the unit although it's not clear which goes to which connector. I've tried it both ways.
The blocks are labeled such that it appears the extensions are on the left of the blocks and incoming lines on the right.
I've tried to connect a phone to several different pairs (I assume this is a two wire system) on the left side of the 66 block with no result. The phone I tried is a ETW-16D-1 and I don't get any display on the phone at all.
Just in case I've tried the system reset on the cpu card.

Terry,
The simplest answer to your querry might be that the ETW phones use the two outside wires (yellow/black) for signals, whereas the DTP/DTU phones use the regular red/green pairs.
If there was no changes to your programming (or if the original programming was left in-tact, try connecting your ETW phone (using yellow/black pairs) to the white/blue pair of your first AMP connector (the one closest to the wall). That should give you at a minimum a dial-tone or display.
As far as the MDF pinouts are concerned, each of the AMP connectors have 25 pairs, and each of the slots are assigned 8 pairs, starting at slot #1. So, slots 1-3 = AMP#1, Slots 2-6 = AMP#2, and 7&8 = AMP#3.
In your case, all of AMP#1 pairs should give you station signals, AMP#2 (first 8 pairs) should give you ANALOG station side signals, while AMP#3 (first 8 pairs) is where you connect your incomming CO lines.
This should get you started. If you need to reprogram the voicemail etc, then getting a manual would be extremely helpful.
