Examples Of Adsl-Dmt Interface Configuration; Figure 7-2 Adsl Atm Configuration - Lucent Technologies Stinger MRT 19 Getting Started Manual

Examples of ADSL-DMT interface configuration

In Figure 7-2, an ADSL-DMT interface in a Stinger MRT 23 unit is configured to
support a rate-adaptive connection to a CellPipe™ 50A CPE. The Stinger MRT 19 is
configured to provide the same support in the same way. However the MRT 19 will
not have an associated switch in the central office, or POTS splitter at the customer
location, as shown for the MRT 23.

The following commands configure the interface to use a constant, planned
(operator-controlled) bit rate of 56Kbps upstream and 1.5Mbps downstream, using
the fast channel in both directions:
admin> read al-dmt { 1 1 4 }
AL-DMT/{ shelf-1 slot-1 4 } read
admin> set enabled = yes
admin> set line-config line-latency-up = fast
admin> set line-config line-latency-down = fast
admin> set line-config rate-adapt-mode-up = operator-controlled
admin> set line-config rate-adapt-mode-down = operator-controlled
admin> set fast-path-config planned-bitrate-up = 56
admin> set interleave-path-config planned-bitrate-down = 1500
admin> write
AL-DMT/{ shelf-1 slot-1 4 } written
The following commands configure the interface to automatically select the best
possible rate at startup time. They specify a possible upstream bit-rate range of
56Kbps to 256Kbps and a possible downstream bit-rate range of 512Kbps to 1.5Mbps.
They also specify use of the interleaved channel in both directions.
admin> read al-dmt { 1 1 4 }
AL-DMT/{ shelf-1 slot-1 4 } read
admin> set enabled = yes
