The following illustrations show a typical progression of loopback tests (i.e. starting

by checking the coax segment at the local side, then the coax segment at the

remote side, etc).

Pseudorandom Bit Sequence (PRBS) Testing

To test using Pseudorandom Bit Sequence, configure the iMcV-DS3/E3/STS

modules for No Loopback, then configure the Transmit Data Source to “Transmit

Pseudorandom Bit Sequence.” Configure the local device for loopback, conduct

the test, then check the

PBEO

LED to verify errors were not received (Refer to the

LED section for more information).
