G.DMT ADSL signal
ANSI T1.413 ADSL signal
G.Lite ADSL signal

G.992.5 ADSL2+ signal
G.992.3 ADSL2 signal
G.992.1 ADSL (DMT) signal
G.DMT ADSL signal

ADSL/2+ Annex B:
Enables Annex B mode. (Screen layout differs slightly on BX100A and BX100V models)
In Annex B systems, where voice (ISDN) is used on the same line, the frequency spectrum can be outlined as follows:
0-80 kHz is allocated to ISDN service (160kbps full duplex and 2B1Q line coding). For 4B3T line coding, frequency
allocation is slightly different.
80-120 kHz is typically a guard band
120-276 kHz is for Upstream data
276-1107 kHz is for Downstream data (ADSL)
276-2208 kHz is for Downstream data (ADSL2+)
