BERT Results

Graph:

• All SONET/SDH alarms, Interface related alarms like Tx/Rx Frequency, Power, Sync Loss, and Bit Error events are plotted in a real time “Event Graph”
• The events are categorized into Path, Line, Section, Bert and Interface events. Whenever any Path alarm is active, the Path event is plotted as a point with the color indicated next to the graph. Similarly for Line, Section, Bert (Bit Errors and Sync loss alarms) and Interface related alarms/errors. Each category is plotted with a different color and in a separate line


Graph



• Up to 7 days of history data for all events are available in the graph and can be drilled down to the second level
• Minute/Hour/Day/7 days views available. User can switch between views anytime. At larger time scales, the results are summarized over appropriate time periods for easy event viewing

PoS and ATM Bert:

• User defined PoS Header fields – define various IP/UDP fields like Source/Destination IP Addresses/ UDP ports etc.


PoS Header fields



• User defined ATM Header fields – define various ATM header fields like UNI/NNI choice, GFC, VPI/VCI etc.


ATM Header fields



• Bandwidth control for PoS Bert - set bandwidth in Mbps, link percentage etc.


Bandwidth control for PoS Bert



• Bandwidth control for ATM Bert - set percentage or Traffic Cell to Idle cell ratio


Bandwidth control for ATM Bert

Impairment Generation:

• Alarm Generation – generate LOF, AIS-L, RDI-L, AIS-P, LOP-P, RDI-P, UNEQ-P alarms
• Error Insertion – insert B1/B2/B3, REI-L, REI-P errors – both Single as well as rate (10^-4 to 10^-9)
• Bit Error Insertion – insert single as well as Rate bit errors rate (10^-3 to 10^-9)
• Sonet Pointer and Justification – inserts new pointer value
• Insert Justification – it increments (Positive) or decrements (Negative) the pointer value by one

Impairment Generation

Alarms/Error Monitoring

• Monitors and reports all SONET/SDH alarms - Section, Line, Path alarms (SONET) or RSOH, MSOH, HP alarms (SDH)

• Display of LED status for each alarm shows No Error (Green), History (Yellow) and Error (Red) for easy identification at a glance
• Display count and seconds for each alarm
• User selectable SONET or SDH terminology


SONET/SDH alarms



• Monitor and report alarms for Tx/Rx Clock Frequency and the frequency deviation (in ppm)
• Monitor and report alarms for SFP power (Tx/Rx power) and SFP temperature, including the SFP Power/Temperature Alarm and Warning thresholds, read from the SFP itself

• Summary of the alarms for all ports, so that user will know all the port status at a glance

• Different colors for alarms summary for easy identification of problems - Red (Alarm Active), Yellow (Alarm History) and Green (No Alarms)

Scan Application

SonetExpert™ scans incoming SONET/SDH traffic, analyzes the frames, detects and reports the structure of the incoming traffic, down to the T1 E1 level. It identifies the various sub pipes within the main pipe, and also the entire structure of each sub pipe right down to the T1 E1 level.

• Supported on OC-3/STM-1, OC-12/STM-4, OC-48/STM-16 and OC-192/STM-64 rates
• Graphical display of the traffic structure for easy visualization
• Identifies and displays sub channels up to STS-1
• Indicates equipped and unequipped sub channels in different colors for easy identification
• Shows substructure of each STS-1 pipe, right down to the T1 E1 level
• User selectable SONET or SDH terminology
• Supported on both the ports independently

The below screenshot shows result of scanning incoming traffic on OC-192. The scan shows that the OC-192 contains 4 OC-48 pipes within, and shows details of each of the 4 OC-48s in a separate tab. For each OC-48 further shows details of the OC-12s, and in turn details of the OC-3s within the OC-12s, down to the STS-1 level. For each STS-1, shows the details of the traffic structure contained within the STS-1. The equipped channels are clearly marked in Blue so that user can easily make out which channel is equipped with a quick glance.

OC-192 with substructure

The above screenshot depicts, OC48 #1 contains an equipped channel → OC12 #1 (OC12 #1_1) → OC-3 #4 (OC-3 #1_1_4) → STS-1 #1 (STS #10 overall STS numbering). The STS-1 #1 is equipped channel, which contains VT1.5s within it, as shown. On clicking on the substructure button, the detailed substructure is shown above. It shows 28 VT1.5 channels, and within it, the VT1.5 on Row2, column 3 is equipped as shown in Green.

OC-192 Concatenated

The above screenshot shows result of scanning incoming concatenated OC-192 traffic. It just shows a single pipe containing STS-192C signal.

The below screenshot shows exact scan result as OC-192 with substructure, but with the terminology changed to SDH instead of SONET. User can change the terminology anytime.
