I would like to add to this post,but from a BCM 400 system. This one is not net worked so I use IE and log into system to make changes.
I am actually more familiar with using the telephone set to do most applications, however, this particular BCM will not keep time stable
when using telephone.
It will keep stable time if I log in with PC. To do so I connect to lan port and then use default IP. I then log into BCM, open up system, then idenity. This brings me to the time and date field where I am allowed to chg time.
Today I was thrown a curve when CCR quit working after I logged in.
Not too sure why it did this, unless perhaps, system had to wait for a while before updating.
Just thought I would add to post in a "for what its worth" perspective.
