On a telrad Digital 400 system I have a HONS SLT card and a ONS SLT CARD. On both cards port one is bad. The port will allow the phone connected to ring but it acts like there is no battery, it will not give dial tone and if it does only for a second or two.
My guess is that there is a blown component on the card and wondered if anyone could point me to that component before I spring for a new card or send out for repair.
Thanks Stu
