. Severe Errored Framing Second. A second with one or more out-of-frame errors or an
AIS error.
. Line Errored Seconds. The number of seconds during which one or more Line Code
Violation errors have occurred (see also the definition of Line Code Violation below).
. Controlled Slip Seconds. A one-second interval with one or more controlled slip errors.
Controlled slip errors are the replication or deletion of the payload bits on a frame. Such an
error may occur when there is a difference between the timing of a synchronous receiving
terminal and the received signal.
. Path Code Violations. A frame synchronization bit error in EF/
or a or frame synchronization error in the T1-
CRC
frames.
. Line Code Violations. The occurrence of either a bipolar violation or excessive zeros
error. A bipolar violation is the occurrence of a pulse of the same polarity as the previous
pulse. In

the previous without being part of the zero substitution code. An excessive zeros error is the
occurrence of more than 15 contiguous zeros in an
it is the occurrence of seven (7) or more contiguous zeros.
