2e3 — Sends a pseudo-random 2^3 -1 pattern
2e9 — Sends a pseudo-random 2^9 -1 pattern
2e15 — Sends a pseudo-random 2^15 -1 pattern.

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.
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.
