If I recall a conversation with Kevin correctly, all TDM400 cards prior to Rev I were rj11's. With the Rev J card, the connector was changed to something that looks very close to an rj45 but has a different number. The rj45-like connector was used for telco standard's compliance in one/more of the non-US countries (forgot which ones). At the time of the rj45-like change, there were also some minor pstn line filtering components added to address those same compliance issues. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
