downstream sync speed of 24 megabits per second (Mbit/s). Utilizing G.992.5 Annex M upstream sync speeds of 3.3Mbit/s can be achieved. ADSL2+ extends the capability
transmission speed of G.lite (G.992.2) is 1.5 Mbit/s downstream and 512 kbit/s upstream. The G.lite specification was an accelerated ITU-T effort to drive
telecommunications, ITU-T G.992.1 (better known as G.dmt) is an ITU standard for ADSL using discrete multitone modulation (DMT). G.dmt full-rate ADSL expands
subscriber line (ADSL) G.992.1, G.992.3 (ADSL2) and G.992.5 (ADSL2+). VDSL offers speeds of up to 52 Mbit/s downstream and 16 Mbit/s upstream, over a single
