Frame Relay LMI Expert
Frame Relay LMI Expert is an application that automatically detects Frame
Relay conditions in the network. The application automatically identify which
standard (ANSI, ITU-T or Original LMI) the network is running.
The following LMI statistics are provided to perform a practical Frame Relay
troubleshooting, based on ANSI T1.617, ANSI T1.618, ITU-T Q922 and Q933:
Monitor Frame Relay Sequence Numbers and report missed sequences
Monitor FULL Status (N391) Polling Cycles
Monitor Status Enquiry messages (T391) counters
Monitor PVC Full Status messages and maintain Full Status summary Tables for:
- Active / Inactive PVCs
- Present / New PVCs
- Deleted / Not deleted PVCs
- Monitor error conditions according to Q.933 Annex A, Paragraph A.5
- T392 timers and thresholds
- N392 and N393 counters and thresholds

The Advisor captures all the Frame Relay frames in the link and performs an
automatic study of all the possible DLCIs (1024). This application lets you to
track the most relevant information of each of the virtual channels in the
network. A complete network condition analysis is performed on all the PVCs
present on the link.
The DLCI Measurement displays both the CPE and the Network statistics:
Throughput in kbps
Frame Distribution
Byte Distribution
The following values are provided for both the Line (Network) side and the
Equipment (User) side.
Max., and inst., utilization (%)
Max., inst., and avg. throughput in kbps
Total octets (bytes)
Total frames/packets
Short frames/packets
