Configuring ATM ADSL-DMT interfaces
A Stinger unit creates an Al-Dmt profile for each ADSL-DMT interface in the system. For
example, for an ADSL-DMT LIM installed in slot 14, the system creates the following
profiles:

Overview of the Al-Dmt profile
Various discrete multitone (DMT) standards define the fast and interleaved data latencies for
each direction (upstream and downstream) of ADSL transmission. In the Stinger Al-Dmt
profiles, you set parameters to specify the data rate, signal quality and power, and data delay of
the interface. The Stinger unit references these parameters in the training process.
The following sets of parameters are active in the current software version:
•
Line activation and DMT parameters
Light
Color
Indication
STBY
Orange
The module is a designated spare. The control module
switches traffic to the module if one of the other
modules fails.
ACTIVE
Green
The module or port is fully operational and no errors
have been detected.
FAULT
Orange
The module failed to pass its POST.
BYPASS
Orange
The module is in bypass mode. (The module
redundancy feature is activated.)
PORT
Green
The local and remote ends of the physical line have
achieved frame synchronization, and the local end of
the ATM link has achieved cell delineation.
If the light is not illuminated, the port is inactive.
