W91620 SERIES
above examples will be dialed out only if they do not exceed a total of 32 digits. If the length of the
combined sequences oversteps 32 digits then redialing is inhibited.
Mixed Dialing
1. Definition of mixed dialing:
Mixed dialing is a combination of sequences of normal dialing, repertory dialing, and redialing. The
three examples given for cascaded dialing are also examples of mixed dialing, provided each
sequence is dialed out completely before the next sequence is entered.
2. There is no limitation on the number of digits and sequences in mixed dialing.
3. If a mixed dialing sequence includes redialing, the redialing is valid only as the first key-in.
4. ON HOOK , OFF HOOK , R : The mixed dialing sequences described in the above
examples will be dialed out only if the total number of digits does not exceed 32. If the total
oversteps 32 digits, then redialing is inhibited.
Combination of Cascaded and Mixed Dialing
1. Cascaded dialing and mixed dialing can be combined; each follows the rules described above.
2. To apply redialing to combinations of cascaded and mixed dialing:
ON HOOK , OFF HOOK , R : Redialing will be executed only if the total number of
digits
does not exceed 32. If the total oversteps 32 digits, then redialing is inhibited.
3. If n cascaded sequences with a total of 60 digits have been dialed, then for the (n+1)th cascaded
sequence, either one 4-digit normal dialing sequence or one complete repertory dialing sequence
(length up to 30 digits) may be dialed. The (n+2)th sequence is not accepted for cascaded dialing.
4. After a total of 64 digits of cascaded dialing, mixed dialing can be added.
