We got several defective Meridian 1 Ananlog Message Waiting Line Cards in our company. My boss wants us to repair them. Since most of these defective cards only got small problems as far as we know (such as burned fuse, capacitor leakage etc), we think repairing them won't be too difficult. But we don't have any reference for this kind of repairing. Of course, we have user's manual, installation manual. But they are not for repairing. I am wondering is there any way to get a schematic diagram for this card. That will help us very much.

Any information is appriciated.
