I put a ups on the system. I talked with tech support, what I did first was replace ksu and T-1 software. I backed up first system and restored on different ksu and software, same problem, he told me I copied coruption from first to second system.He told Me to default one and re-enter all data manually,did that, same problem. I replaced all equipment, different SM, TM, KSU and T1-Rel1, power bar fiber connections, still same problem, I am not losing programming, system just recycles. This happens about 2-3 times a day.Could it be phones? I remember an issue years ago,but I thought that just reset that phone? I will try an upgrade next, but they have an old V-Mail.
