Configuring DSL Connections (DSLTNT)

Configuring data transfer rates

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:

1Read in the ADSL-CAP or ADSL-DMT profile:

admin> read adsl-cap {2 3 2} ADSL-CAP/{shelf-2slot-3 2 } read

2Enable the line:

admin> set enabled=yes

3List 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

4Specify a maximum downstream rate:

admin> set max-down-stream-rate=5120000

5Write 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
