Configuring DSL Connections (DSLTNT)
Configuring data transfer rates
APX 8000/MAX TNT/DSLTNT Physical Interface Configuration Guide Preliminary May 9, 2000 17-7
For example, if the transceiver is configured for 1088000bps and the loop quality is so poor
that the transceiver will not connect to the remote side, the transceiver does not automatically
adjust the down-rate into the 952000bps range. The administrator needs to configure the
Max-Down-Stream-Rate to the lower rate.
Note: For more information about the Max-Downstream-Rate parameter, see the APX
8000/MAX TNT/DSLTNT Reference. Note that although the Max-Upstream-Rate parameter
appears in the ADSL-CAP and ADSL-DMT profiles, it is not currently supported.
To configure the maximum data rate for an ADSL connection, proceed as in the following
example:
1 Read in the ADSL-CAP or ADSL-DMT profile:
admin> read adsl-cap {2 3 2}
ADSL-CAP/{ shelf-2 slot-3 2 } read
2 Enable the line:
admin> set enabled=yes
3 List the Line-Config profile:
admin> list line-config
[in ADSL-CAP/{ shelf-2 slot-3 2 }:line-config]
trunk-group = 0
nailed-group = 1
activation = static
call-route-info = { any-shelf any-slot 0 }
data-rate-mode = autobaud
max-up-stream-rate = 1088000
max-down-stream-rate = 2560000
4 Specify a maximum downstream rate:
admin> set max-down-stream-rate=5120000
5 Write the profile:
admin> write
Configuring data transfer rates for SDSL lines
The 16-port SDSL card only supports a maximum symmetric data transfer rate of 784Kbps.
You can, however, configure the 24-port SDSL-HP card maximum data rate using the
Max-Rate parameter in the SDSL line profile. The Max-Rate parameter supports the following
values:
• 144000
• 272000
• 400000
• 528000
• 784000
• 1168000
• 1552000
