Call Restriction Summary

After the individual telephone forms have been completed, Form 6g, Call
Restriction Assignments and Lists, can be used as a summary and telephone
programming aid for telephone calling restrictions as designated in this chapter.
NOTE:
On Form 6f (page 3), Disallowed List 7 contains factory set entries—
that is, it is the factory set disallowed list. To change the entries in
this list, cross out the entry and write the new values in the space
provided.
On Form 3a (page 3), in the Class of Restriction without Barrier
Codes section, write the list numbers under the Disallowed List

On all copies of Form 3a (page 4), Class of Restriction with Barrier
Codes, write the list numbers under the Disallowed List Access
heading for each barrier code.
