* GE 100-call plan Z is tone groups C’ + C’; use (100-call format).
For capcodes ending in double-digits that use the same tone group for both tones,
(example: pager capcode 122 in a code plan C), use the diagonal tone as one of the tones.

Notes: 1) On General and Modified General plans, there are different diagonal tones for different
pager blocks. 2) For General Alternate Code Plan, last two digits of capcode are the same as each
other.
