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”
• Events are grouped into major groups and plotted in the graph. E.g: Bit Error and Sync loss events are grouped under Bert group, all Path alarms under Path group, all Line alarms under Line group, all Section alarms under Section group, all Interface related alarms under Interface group. User can click any event plotted on the graph, and the details of all the alarms present for the event will be displayed next to the graph including all the alarms present within each group


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

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)

Record & Playback

Record Application

• Capture on both ports simultaneously to a file on hard disk in GL's proprietary HDL format
• Capture PoS traffic (PPP packets), ATM traffic (ATM cells), or Raw SONET/SDH traffic (Raw SONET/SDH frames)
• Multiple Versatile filters (e.g PPP, IP, UDP etc for PoS, VPI, VCI and other ATM Header fields for ATM) can be applied for incoming PoS/ATM traffic to capture traffic of interest. Up to 16 hardware filters can be applied to each port. Hardware filters work at wire speed
• Hardware timestamping of captured traffic
• Onboard 8GB of DDR3 RAM memory to temporarily store the captured traffic before transferring it to the PC. Out of this 8GB, 4GB is used for the Record application and 4GB for the Playback application
• Capture based on different criteria - Size, Number of frames etc.
• Split capture into multiple files, for easy handling of small size files
• Multiple Record instances supported in parallel

Record Application

Playback Application

• Playback from file (previously captured file) on both ports simultaneously
• Playback PoS traffic (PPP packets), ATM traffic (ATM cells), or Raw SONET/SDH traffic (Raw SONET/SDH frames)
• Playback on the same ports as captured, or playback on User selected ports
• One shot playback - stop playback once end of file is reached, or Continuous playback - start over from the beginning once end of file is reached
• Playback specified number of frames only and stop
• Supports multiple playback instances in parallel, but only when multiple devices are connected. For example, one instance can playback on one device, while another instance can playback on another device

Playback Application

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.
