Toshiba Strata Cabling??

Nov 12, 2006 1 Replies

Is anyone familiar with the Toshiba Strata DK280 PBX? I'm not a professional installer - just a guy trying to fumble through it ;) It's a DKSUB280A. I don't have any documentation, and I need to know 2 things:


1) On the PDKU2 card in slot S11 has a 50 pin amphenol connector where the phones connect to the system. Do I punch down the other end using pairs, ie. 1&2, 3&4 etc. or 1&26, 2&27, etc?


2) On the two cards where the telephone lines come in, there are four RJ25 input jacks - two on RC0U1 in slot S12, two on RC0S1 in slot S13. Based on my recollection, I believe not all six pins are used, just the



  1. Does it only use pins 3&4, and 2&5?

Arrrgghhh!! Please, please, can anyone help me???
