字段说明

E1 0 is up 显示E1控制器的的状态。 这个状态可以是UP，Down 或 Administratively Down。打环时会显示Locally looped 或remotely looped。
Applique Type 控制器的Applique Type 和 indicate 可以是Blanced 或 Unbalanced
Framing 默认是有CRC4校验的
Line Code 默认E1线路的line code是HDB3
No Alarms detected

如监测到任何报警信息，会显示在当前位置。可能会出现的报警信息有：

  • Transmitter is sending remote alarm.

  • Transmitter is sending alarm indication            
    signal (AIS)。

  • Receiver has loss of signal.

  • Receiver is getting AIS.

  • Receiver has loss of frame. 

  • Receiver has remote alarm. 
    Receiver has no alarms. 
Data in current interval(251 seconds elapsed)

Shows the current accumulation period, which          
rolls into a 24 hour accumulation every 15            
minutes. The accumulation period is from one            
to 900 seconds. The oldest 15?minute period            
falls off the back of the 24?hour accumulation            
buffer.
Line Code Violations

Indicates the occurrence of either a Bipolar          
Violation (BPV) or Excessive Zeros (EXZ)            
error event.
Path Code Violations

Indicates a frame synchronization bit error in          
the D4 and E1?no CRC formats, or a CRC            
error in the Extended Superframe (ESF) and            
E1?CRC formats.
Slip Secs

Indicates the replication or deletion of the          
payload bits of a domestic trunk interface            
(DS1) frame. A slip might happen when there            
is a difference between the timing of a            
synchronous receiving terminal and the            
received signal.
Fr Loss Secs

Indicates the number of seconds an Out of          
Frame (OOF) error is detected.
Line Err secs

Line Errored Seconds (LES) is a second in          
which one or more Line Code Violation errors            
are detected.
Degraded Mins

A degraded minute is one in which the          
estimated error rate exceeds 1E?6 but does not            
exceed 1E?3.
Errored secs

     In ESF and E1 CRC links, an errored second is          
a second in which one of the following defects            
is detected:

  • One or more Path Code Violations.

  • One or more Controlled Slip events. 

For SF and E1 no?CRC links, the presence of          
Bipolar Violations also triggers an errored            
second.
Bursty Err secs

A second with more than one but fewer than          
320 Path Coding Violation errors, no Severely            
Errored Frame defects and no detected            
incoming AIS defects. Controlled slips are not            
included in this parameter.
Severly Err Secs

     For ESF signals, this is a second in which one          
of the following defects is detected:

  • 320 or more Path Code Violation            
    errors.

  • One or more Out of Frame defects.

  • An AIS defect.

For E1?CRC signals, a second with one of the          
following errors:

  • 832 or more Path Code Violation            
    errors.

  • One or more Out of Frame defects

     For E1?nonCRC signals, this is a second with          
2048 Line Code Violations or more. For D4            
signals, this means a count of 1?second            
intervals with Framing Errors, or an Out of            
Frame defect, or 1544 Line Code Violations
Unavail Secs

     For E1?nonCRC signals, this is a second with          
2048 Line Code Violations or more. For D4            
signals, this means a count of 1?second            
intervals with Framing Errors, or an Out of            
Frame defect, or 1544 Line Code Violations
