NTERFACE ONFIGURATION
Setting margin can affect maximum rate of the line. When line condition is good,
you can set a small margin to obtain higher rate. When much noise is around the
line, this may cause disconnection however.
By default, current-margin-value is set to 2 and snext-margin-value is set to 0.
# Set the SNR target margin to 5 on interface ATM 5/0.

2: Two-wire mode.
4-auto-enhanced: Four-wire auto-switch mode. When this mode is enabled, the
four-wire enhanced mode is used first when the local end negotiates with the
remote end. If the remote end is not operating in four-wire enhanced mode, the
local end uses the four-wire standard mode for negotiation. When four-wire
auto-switch mode is adopted, the remote end can be set to operate in four-wire
enhanced mode or four-wire standard mode.
4-enhanced: Four-wire enhanced mode. In this mode, the two pairs of the four
wires can start negotiation separately; in addition, the remote end must be set to
operate in four-wire enhanced mode as well.
4-standard: Four-wire standard mode. In this mode, the two pairs of these four
wires must start negotiation at the same time; in addition, the remote end must
be set to operate in four-wire standard mode as well.
