CTS 710 SONET Test Set User Manual
The bytes that cannot be edited are marked with a line of asterisks on
the TRANSPORT OVERHEAD or PATH OVERHEAD pages (see
Figure 3–28 on page 3–79).
In addition, there are bytes you may not be able to edit depending on
parameter settings in the CTS 710. As shown in Figure 3–28, a short
text string replaces the binary values in the byte field of the
TRANSPORT OVERHEAD and PATH OVERHEAD pages when a
byte cannot be edited. Table 3–9 shows the affected bytes, the text
string, and a description of the parameter setting that prevents the
byte from being edited.
