Connect Systems used to make a box like this too, one that did PL, DPL, and DTMF, and another that did LTR...it was also nice setting up a new community rptr! CD-1 and CD-2??? Just checked: CD-2 is the PL/DPL decoder w/DTMF, LT-2 is the LTR decoder. And they still carry both. > http://www.connectsystems.com/public_html/products/cd2.htm
