[mod.telecom] { line noise

I remember that several months ago we were discussing some line noise that
came in the form of '{' characters on a periodic basis.  Can anyone out there
tell me what they found, and if the problem was ever corrected?

We just recently went to a new all digital 5-ESS; that's when the
noise started.  I have also noticed that we only get it using Bell 212
protocol.  The Vadic 3400 protocol seems to be immune to it.
