Page: 31 / 383

Pattern:
Use the pattern drop-down box to select the test pattern which will be inserted into the transmitted signal. Pseudo
Random Bit Sequences (PRBS) defined by ITU-T 0.150 and 0.151 standards, fixed words and 24-bit or 32 bit user defined
patterns are available.
Note: If the 32 bit user pattern entered is incorrect, the default pattern will be 0xFFFFFFFF.
Invert:
Inversion of polarity is also available.

6.3.2 Receiver Setup
Hierarchy
Tapping the Hierarchy setup box opens the Rx Hierarchy screen. The Hierarchy setup options for the Rx are the same as for the
Tx described previously.
Interface
Tapping the Interface setup box opens the Rx Interface screen. The Interface setup options for the Rx are the same as for the Tx
described previously, except for clock offset, which is not possible.
Note: Remember to use an optical attenuator to prevent receiver overload or damage – refer to the SFP chart below to determine
safe levels. Avoid looping back the Tx and Rx on a 1550nm XFP or SFP using a patchcord only as this will damage the SFP.
Structure
Tapping the Structure setup box opens the Rx Structure screen. The Structure setup options for the Rx are the same as for the
Tx described previously.
Payload
Tapping the Payload setup box opens the Rx Payload screen. The Payload setup options for the Rx are the same as for the
SONET Tx setup described previously.
