Modifying the Operating Mode
To modify the operating mode of a DMT profile, follow these steps:
To set the operating mode of a DMT profile to the default mode, follow these steps:
An ADSL line uses one of these operating modes:
• auto—An ATU-C port that employs this operating mode automatically detects the capabilities of
the ATU-R CPE and uses a startup sequence specified by either G.992.1, G.992.2, or T1.413-1998.
Auto mode is the default for an ADSL line.
• g992-1—In this mode the line uses the G994.1 startup sequence. After startup, the line complies
with G992.1 operation.
• g992-2—In this mode the line uses the G994.1 startup sequence. After startup, the line complies
with G992.2 operation. (G992.2 is also known as G.lite.)
• t1-413—This mode forces the ATU-R CPE to use the T1.413-1998 startup sequence.
