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
