PECTRUM SSUES
The asymmetric 776 kbps spectrum, defined in ANSI T1.418 Issue 2, allows the HDSL4 product to be spectrally
compatible with ADSL services in adjacent pairs in the same binding groups for all non-doubler applications. A
combination of asymmetric and symmetric spectrums is used for ADSL compatibility in doubler applications.
