.................................................... Overview a l - d m The TAOS software creates an t profile for each interface in a Stinger VDSL LIM.

Introduction a l - d m t In the profile, and the subprofiles they contain, you set parameters to specify the data rate, signal quality and power, and interleaving delay of the interface.

0dB margin LIM power vs. noise On many loops, a Stinger VDSL LIM that has trained to ADSL or ADSL2+ protocols uses large power margins.
