ASSIA Climbs to Layer 2
So far, the company's technology has only checked a DSL connection at the physical layer, and that left some problems open. Specifically, certain modems or firmware weren't able to re-establish a Layer 2 connection after undergoing physical-layer changes, says Jerome Joanny, ASSIA's senior director of product management.
DSL Expresse can now check a modem to predict if this problem will come up. The software has to be customized for particular manufacturers' modems, so the feature is an optional one.
Why this matters
Layer 2 capabilities could open up a new group of diagnostic capabilities for ASSIA. One possibility -- which Joanny discussed with Light Reading but did not say is imminent or even certain -- would be to track bandwidth-usage trends to help operators with network planning.
