Break Out! You found it! The most robust, flexible RJ-21 to RJ-11 bridging adapter made. We once used the AT125 ourselves.  It just isn't built right. The plastic cracks. The connectors are cheap.  Pins fall out. You deserve more. We redesigned from scratch in the USA. We doubled the case strength, improved the board, and added quality gold-plated RJ-11 and RJ-21 connectors. Then we built thousands to cut cost. Universal Connection Having both male and female AMP connectors give you complete flexibility.  Use either connector, or use both.  Loop through for a passive "tap" connection.
