ADSL Section
ADSL Section
ADSL (Asymmetric Digital Subscriber Line)
is designed to deliver more
bandwidth downstream (from the central office to the customer site) than up-
stream. This section (see
Figure 1) is used to configure ADSL operation type
and shows the ADSL status.
FIGURE 1
ADSL Parameter panel
ADSL >> PARAMETERS
The menu item allows you to specify the ADSL standards to operate with. You
may explicitly set a specific standard, or choose
“Automatic”
to automatically
negotiate with remote DSLAM.
Figure 2 shows the ADSL standards selection on
ADSL Parameter
menu.

Fast Path FEC Correction
There are two latency paths that may be used: fast and
interleaved. For either path, a forward error correction
(FEC) scheme is employed to ensure higher data
integ-
rity.
For maximum noise immunity, an interleaver may be used
to supplement FEC
