SX-200 12cct ONS Line Card - 02/24/17 05:51 PM
My question is regarding compatibility- I have a 12cct Digital Line Card that failed recently with a part number "0109-010-000". I'm looking online for a replacement and I see some that are decently priced that have a little different part number like "0109-010-002", and "0109-010-000 SA". What does the SA mean on the part number? The card was being used to attach analog phones to the system.
