are detected. I.e., tally increments if more
than 7 consecutive zeroes in the received
data stream are detected under B8ZS line
coding, or if 15 consecutive zeroes are
detected under AMI line coding.
Signaling has been frozen at the most
recent values due to loss of frame
alignment, loss of multiframe
alignment or due to a receive slip.
Line loopback deactivation signal has
been detected in the receive bit stream.

The frequency of the transmit clock is less
than the frequency of the transmit system
interface working clock. A frame is
