Diagnostic Testing
Testing DSL copper loops
The following sample commands enable a BERT on port 1 in slot 4 for 5 minutes:
admin> read line-diag {1 4 1}
LINE-DIAG/{ shelf-1 slot-4 1 } read
admin> list
[in LINE-DIAG/{ shelf-1 slot-4 1 }]
admin> set bert-timer = 5
admin> set bert-enable = yes
admin> write
LINE-DIAG/{ shelf-1 slot-4 1 } written
The line-diag-stat profile includes parameters that report the status of the line and
the result of the test. To determine the status of the BERT, use the get command to
display the setting for the bert-operation-state parameter. For a list of all the
possible states of the line, see the Stinger Reference . The BERT is complete if the value
for the bert-operation-state parameter is stopped . For example:
admin> get line-diag-stat {1 4 1} bert-operation-state
[in LINE-DIAG-STAT/{ shelf-1 slot-4 1 }:bert-operation-state]
bert-operation-state = stopped
To show any BERT errors detected, display the setting for the
bert-error-counter
parameter. For example:
admin> get line-diag-stat {1 4 1} bert-error-counter
[in LINE-DIAG-STAT/{ shelf-1 slot-4 1 }:bert-error-counter]
bert-error-counter = 0
Testing DSL copper loops
The following features allow for testing of DSL copper loops. The galvanic isolation
feature disconnects up to 48 ports on a Stinger line-interface module (LIM), leaving
the lines open for testing. With the multiple port tone generation feature, you can
send a trace tone to up to 48 ports simultaneously. The tone is obtained from an
external generator connected to the external test terminal on a path selector module
(PSM) or copper loop test (CLT) module.
You can use the line-tests profile or the isolate and gen-tone commands to
perform these tests.
You can perform more comprehensive line tests by using a Stinger Copper Loop Test
(CLT) module. For more information, see the
Stinger Copper Loop Test (CLT) Module
Guide .
Using the
line-tests
profile
Each LIM has an associated
line-tests
profile. You use the
line-tests
profile to
activate both the galvanic isolation and multiport tone tests. Following are the
line-
tests
parameters with their default values:
[in LINE-TESTS]
physical-address* = { shelf-1 slot-5 0 }
clt-slot-number = slot-13
start-port = 0
end-port = 0
port-activation-array = [ no no no no no no no no no no no no no no +
