PRBS Generator and Monitor Mode

The PRBS Generator and Monitor mode causes a port to generate and transmit Pseudo Random Bit Sequences online while it tries to synchronize on the received signal.

Use this mode only with Telco agreement. Also, when you use this mode, make sure that remote equipment is set to loopback mode.

To select this mode, select PRBS Generator and Monitor mode on the Port Test Configuration dialog (shown in Figure E-2 on page 103).
