We have been very successful with recovering a customers machine after a disk or cache failure. We have worked on hundreds of machine recovery's and have been very successful.
We can do specific projects like upgrade the networking equipment at the Cellsite(s) or diagnose and repair microwave FH or BH. We DO NOT climb towers but can sub this out. Most companies have their own climbers and send us the equipment and details to install. We can splice fiber in the cabinets or coming off of the tower if needed but do not dig.
We offer very custom programming services to be able to move all of your programs and data to the AS/400. Current source code will need to be present or a rewrite of the software would need to be performed which we can do.
We can repair any model System 36 or AS/400 power system. Oldest mainframe we work on is z/9.
