I have an ESI IVX ksu. My customer moved into a vacant suite and asked us to clean up the phone closet and re-do the cable. Seems the old tenant left in a hurry, and abdonded the KSU. I don't know much about it. I assume it works. Customer said we could move the unit and keep the change. So if your interested, and need more info, just let me know.

Just an update... This is an S-Class Gen II unit with power supply.

what are you asking for it
