The Billion 8800NL combines an ADSL/ADSL2+ modem, for conventional broadband services with a VDSL2 modem for FTTC fibre broadband services. It also incorporates target SNR margin adjustment for ADSL and ADSL2+ services.

Target SNR margin adjustment with the 8800NL can significantly improve download speeds for many broadband users as it means they are no-longer dependent upon exchange Digital Line Management (DLM) systems, which can increase the target SNR margin to very high levels (substantially reducing download speed).
