T1 Statistics: Field Definitions
Field
Name
Values Description
Red Alarm Integer tally of
alarms counted
since last reset.
The alarm condition declared when a device
receives no signal or cannot synchronize to the
signal being received. A Red Alarm is
generated if the incoming data stream has no
transitions for 176 consecutive pulse positions.
Blue Alarm Tally since last
reset.
Alarm signal consisting of all 1’s (including framing
bit positions) which indicates disconnection or failure
of attached equipment.
Loss of Frame
Alignment
Tally since last
reset.
Loss of data frame synchronization.
Excessive
Zeroes
Tally since last
reset.
Displayed value will increment if consecutive
zeroes beyond a set threshold 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.
Status Freeze
Signaling
Active
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
Line loopback deactivation signal has been
detected in the receive bit stream.
Transmit Line
Short
A short exists between the transmit pair for
at least 32 consecutive pulses.
Transmit Data
Overflow
For use by MTS Technical Support
personnel.
Transmit Slip
Positive
The frequency of the transmit clock is less
than the frequency of the transmit system
interface working clock. A frame is
repeated.
