Lucent Technologies 7820-0802-003 Configuring per-session data rates using modem rate control

	Configuring DSL Connections (DSLTNT)
	Configuring data transfer rates
Parameter/RADIUS attribute	Specifies
Ses-Rate-Mode/	Per-session DSL data rate mode. The default setting,
Ascend-Dsl-Rate-Mode (97)	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/	Per-session ADSL-CAP upstream data rate. Not
Ascend-DSL-Upstream-Limit (98)	currently supported.
Ses-ADSL-CAP- Down-Rate/	Per-session ADSL-CAP downstream data rate. The
Ascend-DSL-Downstream-Limit (99)	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/	Not currently supported.
N/A
Ses-ADSL-DMT- Down-Rate/	Not currently supported.
N/A
Rx-Data-Rate-Limit/	Maximum data rate (in kilobits per second) to be
N/A	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/	Maximum data rate in kilobits per second to be
N/A	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.

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.
