Figure 4-12 Sync PID List Page
The display fields and columns in the Sync PID List (Figure 4-12) have a similar meaning to
the Async PID List fields and columns, with following exceptions:
Column/Field Description
Inverted X.21
Mode This selects normal X.21 balanced signals, or inverted X.21
balanced signals for countries where X.21 signals are reversed.
PID Rate This field specifies the output clocking rate of the Sync Port in bits
per second. Allowable values are between 1 and 10000000 bps
inclusive. The actual output rate of the sync port may vary around
this value by up to 10 parts per million to compensate for jitter in the
incoming data.
