Directory
The DSU’s dial backup Directory (Dir) can store up to
ten telephone numbers (dial strings) so the DBM can call
other DBMs. Directory entries are numbered from 1 to 10.
Each dial string in the directory can be up to 36 characters
in length. Refer to Table 4-6 for numbers and characters
that can be used.
When the dial string or changes are complete, enter an
underscore ( _ ) to the immediate right of the last
character;
this ends the dial string field
.
