Chain Dialing Buffer
The chain dialing buffer may be divided into four sections, allowing up to four numbers to be dialed
out in sequence. For example, if the user enters M01, M03, EM1, and normal dialing (manual dialing),
the content of sections 1 to 4 will be M01, M03, EM1, and normal dialing (manual dialing). When
numbers are entered into the chain dialing buffer, there is no need to wait until the previous dialing
sequence has been completed. Numbers may be entered directly, one after the other, even while
previous numbers are being dialed out.
1. Manual Dialing + Repertory Dialing
Redial buffer content = Manual dialing + Repertory dialing
2. Repertory Dialing + Manual Dialing
Redial buffer content = Repertory dialing + Manual dialing
3. Repertory Dialing + Repertory Dialing
Redial buffer content = Repertory dialing + Repertory dialing
4. Redialing + Manual Dialing
Redial buffer content = Redialing + Manual dialing
The primary redial content may not be manual dialing, or else the last redial content will be
overwritten.
5. Redialing + Repertory Dialing
W91590 SERIES
Publication Release Date: July 1995
- 11 - Revision A3
Redial buffer content = Redialing + Repertory dialing
Redialing is valid only as the first key-in after off-hook or after the handfree dialing function is
toggled on.
The second sequence should not be performed until the first sequence is completely dialed out.
6. Manual Dialing + One-Key Redialing
Redial buffer content = Manual dialing
The One-key redial may only be used after dialing out of a manual dialing sequence is completed.
7. Repertory Dialing 1 (M1) + One Key Redialing +
Repertory Dialing 2 (M2) + One Key Redialing
or
Repertory Dialing 1 (M1) + One Key Redialing +
Repertory Dialing 2 (M2) , ON HOOK , OFF HOOK , Redialing
M1 and M2 represent any of the repertory dialing memories.
The first redialing will dial out M1; the second will dial out M1, M2.
If dialing out of the repertory dialing memories has not been completed, the one-key redial key will
be ignored.
Dialing of the second repertory dialing memory (M2) should not be performed until the one-key
redialing operation is completed.
Notes:
1. Chain dialing (cascaded dialing) allows for memory or manual dialing while a previous dialing sequence is still being dialed out.
2. More than one sequence of manual dialing is not permitted.
Entering more than one manual dialing sequence will inhibit redialing.
Chain dialing of more than four sections is not permitted.
Manual Dialing + M1 + Manual Dialing (two sections of manual dialing)
3. If more than four sections are entered, all sections after the fourth section will be ignored and redialing will be inhibited.
Manual Dialing + M1 + M2 + M3 + M4 (over 4 sections, ignore M4 and inhibit redial)
4. There is a 2.0 sec. inter-chain dialing pause for cascaded dialing.
