D816 Volume Problems

D816 Volume Problems

D816 Volume Problems

There was a bad CO Line position on this unit about 1 year ago so I moved the Line to CO position 3. This worked great....until now.
The customer is experiencing problems with being heard on an outside call. The customer can hear fine.....just the outside caller has a volume problem. This is on all lines and on all sets. I checked the incoming lines at the demarc and they are working good.
I want to change out the 4 CO Line card. How involved is this, other than the standard static precautions and power down etc? Will I Lose programming when I do this?

RE: D816 Volume Problems

piece of cake shut down remove & replace
befor you go through all that agg did you do actual loop current measurements and line voltage ck to make sure its no a C.0. issue

RE: D816 Volume Problems

Thank you cwc3. No Problem with line voltages and no problem hearing at the demarc. I will change the CO Line card.

RE: D816 Volume Problems

Upon further investigation, the first 4 lines are on the motherboard  and it is decision time....buy a new KSU (Norstar which I like better) or a used D816 Hybrid. The choice now depends on what the customer wants to spend.
