Configuring SHDSL Operating Mode on an ATM Physical Interface
To configure the SHDSL operating mode on the physical ATM interface, include the
shdsl-options
Configure the following SHDSL options:

annex —The type of annex:
—Use for North American SHDSL network implementations.
annex-a
annex-b —Use for European SHDSL network implementations.
—The SHDSL line rate. The default for 2-wire mode is auto. The default
line-rate
for 4-wire mode is 4608 Kbps.
—A loopback connection,
loopback
local —Use to troubleshoot physical PIC errors. A local loopback loops packets,
including both data and timing information, back on the local router s PIM.
—Use to troubleshoot physical circuit problems between the local
remote
router and the remote router. A remote loopback loops packets, including
both data and timing information, back on the remote router s PIC.
snr-margin — The SHDSL signal-to-noise ratio (SNR) margin,
SNR margin is the difference between the desired SNR and the actual SNR.
—Current SNR is the difference between desired SNR and the actual
current
SNR. When configured, the line trains at higher than current noise margin
plus SNR threshold.
—Self-near-end crosstalk (SNEXT) SNR margin line trains the line at
snext
higher than SNEXT threshold.
