Description

From the listing uploaded by “appupdater”.

The SFN is a data carrier that provides site failure data back to the product design units to enable them to improve Ericsson product and system performance. This will lead to improved fault detection and performance of the network. When the faulty unit(s) is identified and replaced, the site technician is required to prepare a SFN for each unit. This is best carried out at the site to ensure that accurate information is supplied.
