Alcatel Unleashed

Hi, i have alcatel 4400 system which contains of some operating cards into it like,Z24,UA32,NDDI and SUVG, the problem that i had is that my phone lines into Z24 card are noisy and some of them with no dialtones, and also the same thing heppend with phone lines into UA32 card,getting no dial tones,it seems it is ahardwarem problem,but i need to know which compenent into the card board i have to remove it and fix new one instead of it, there any solutions to fix these problems, thanks in advance.

resistor r45-0/2,capasitor c-90/30 and you fix the problem... just joking

Those cards are phased out around 20 years ago. so i suppose to find it new is impossible.
You need to check if your system accepts ez32-2 (kind also impossible since is it is 4400) and buy it from alcatel partner

Maybe if you search e bay or a stock house. But if you are/have good electronic technician and have the tools and components good luck then.

Regards

Thanks for reply, i know that these type of cards is about to vanish on earth, but i have to deaL with it while it is the only operating system we have, for me i think there is a damged compenent into the board that need to be changed, but i need someone who can tell me what is the damged compenent into the board.
