I think I have an internal Fax server problem... "something" is generating busies, but ran a traffic study on a PRI anyway. The columns are marked MLHPC, MLHINCPC, MLHUSG, MLHOFL. What is MLH? I think I get PC peg count OVFL - overflow, etc. I would expect to see usage at 100 to show busies - correct? I don't see that. I also see Overflow in the last column but I don't have an overflow setup!
