I fell down. and tore the power module out of the mux that demarcs the 44 pris. the ras boxes had a red delta channel til i hupped them. 23 bearers per pri you know, 2 muxes, 1 fully loaded one half, and i tear down the full one. @#$% i said. so i drove a phillips head up through the chassis and pulled the PM back into the backplane and the mux went green, and i freaked out that it worked. but we're getting slow busies off three pri cards still, and i have to dispatch sat.
