Does anyone know if a Sangoma T1 card require an external CSU to connect to a PRI or is it built into the card?

There is a functional csu/dsu on the card, that is it is functional as far as framing/signaling etc, but as it is connected to a long piece of wire that goes out in the big wide world, I personally would not trust it to survive a thunderstorm, the grounding and spark-gaps normal in a telco type csu are unlikely to be up on the card to prevent damage to the card itself and the server also. 50 or 60 bucks on ebay might save you a whole bunch later.
