An MPR-e radio that is connected to the 7705 SAR can automatically upload its received signal level (RSL) history file to the 7705 SAR host. The RSL file contains a history of radio attributes and alarms that radio operators can use to isolate and diagnose radio-layer problems that might exist in the network.
Up to 24 MPR-e radios can independently upload their RSL history file every 15 minutes when the rsl-history command is configured on the 7705 SAR for each radio. When uploaded, the file is stored on the 7705 SAR compact flash. Each RSL file can be up to 1 Mbyte and contain up to 10 000 lines. Each time a new file from a specific MPR-e radio is sent to the 7705 SAR, the new file overwrites the previous version for that radio. Once uploaded to the 7705 SAR, the operator can view the file in its raw format using the file>type command or FTP it to an external server.
