Frequency Drift? - 10/08/12 02:01 PM
So, I have a clinic with a Plain old T1. Our equipment, a Nortel Option 11, is continuously slipping. It will run for a few hours to a few days, and then spend a couple of hours with static, cutoffs, channels lockout, ect.
When we look at the span it is running 4 hz fast and drifts to 5 hz, then back to 4. The telco tech says this is normal?
Doesn't the span need to be exactly 1.544MHz? Not +4 or 5?
