Description This command inserts bit errors into a running BERT test. The number of errors inserted corresponds to
10^(-rate). A rate of 0 will cause 1 error in every bit transmitted. A rate of 7 will cause an error rate of 10^(-
7), or 1 error in every one billion bits transmitted.
The no command disables the insertion of bit errors into the bit error rate test stream.
NOTE: This command is not saved in the router configuration between boots.
Default no bit-error-insertion
Parameters rate — Specifies the bit error rate, expressed as an integer.
Values 2 — 7
buildout
Syntax buildout {long | short}
Context config>port>tdm
Description This command specifies line buildout (cable length) for physical DS-1/DS-3 ports.
Default short
Parameters long — Sets the line buildout for length runs up to 450 feet.
short — Sets the line buildout for length runs up to 225 feet.
