I wanted to do a trunk calibration today on a SL2100 that has been in service for a while. Other issues, but thought this wouldn't hurt. Service is provided by Mediacom coax.
I logged in via a phone and started the test for trunk one. It started the test, then immediately displayed "Error" and quit. I tried other trunks, and waited for all trunks to be idle, but no success. I have not rebooted yet, but that is my next step. Have to wait for a weekend for that.
