In this case there have been no errored seconds in the last 24 hours.
An errored second is any second during which the CRC-6 error checking method has detected an error. Since the CRC-6 is used only on ESF framed T1 circuits, this information is only available if the T1 is ESF.

It is not unusual to see some intervals with a few errors on an acceptable and useable T1 circuit. In our example the NCC card is connected to another CSU just a few feet away, so perfect performance is to be expected.
