Configuring per-session data rates using modem rate control
In the following example, the CPE session will be initially established at the maximum line
rate configured in the ADSL-CAP profile. After the session has been established, the DSLTNT
determines that this session has a maximum downstream rate of 7168000. It then re-establishes
the connection using the specified rate.

Ses-Rate-Mode/
Ascend-Dsl-Rate-Mode (97)
Per-session DSL data rate mode. The default setting,
Autobaud, specifies that the DSLTNT must train up
to a set data rate. If a DSL modem cannot train to this
data rate, it will connect at the closest rate to which it
can train (the modem’s ceiling rate). Currently
Autobaud is the only supported option.
Ses-ADSL-CAP-Up-Rate/
Ascend-DSL-Upstream-Limit (98)
Per-session ADSL-CAP upstream data rate. Not
currently supported.
Ses-ADSL-CAP- Down-Rate/
Ascend-DSL-Downstream-Limit (99)
Per-session ADSL-CAP downstream data rate. The
following rates (in bits per second) are supported:
7168000 (the default), 6272000, 5120000, 4480000,
3200000, 2688000, 2560000, 2240000, 1920000,
1600000, 1280000, 960000, 640000.
Ses-ADSL-DMT-Up-Rate/
N/A
Not currently supported.
Ses-ADSL-DMT- Down-Rate/
N/A
Not currently supported.
Rx-Data-Rate-Limit/
N/A
Maximum data rate (in kilobits per second) to be
received across the connection. The default 0 (zero)
disables the data rate limit feature. The valid range is
from 0 to 64000. If the specified number is larger
than the actual bandwidth provided by the line, the
connection behaves as if the data rate limit were
disabled, except that additional computations are
performed unnecessarily.
Tx-Data-Rate-Limit/
N/A
Maximum data rate in kilobits per second to be
transmitted across the connection. The default 0
(zero) disables the data rate limit feature. The valid
range is from 0 to 64000. If the specified number is
larger than the actual bandwidth provided by the line,
the connection behaves as if the data rate limit were
disabled, except that additional computations are
performed unnecessarily.
