+ PDIU-DS Connected to a Modem-LEDs 01,
02, 03, 04, and 17 ON; all other LEDs OFF
(Refer to Chapter 6-Peripheral installation
for more PDIU-DS/modem pool information).
Program 21 -Modem Pool Port Assignments
With this program, identify modems connected to
standard telephone ports (line side of modem) and
digital/PDIU-DS ports (RS-232 side of modem). Each
selection pair assigns the modem to the system
modem pool. With data security groups (Program 20,
LEDs 17 - 20) and the call the blocking feature
(Program 31, LED 04), modem access can be denied
or allowed to data users.
Notes:
1. When modems are connected to standard
telephone ports (PSTU, RSTU, RSTUZ,
PESU, RDSUHSTS) the Executive/
Privacy Override blocking feature
(Program 31, LED 18) should be enabled
for the modem RSTU, RSTU2, PSTU,
PESU, and RDSU ports for data security.
The LED 18 feature should be disabled to
enable callers to switch from voice to
data, or vice versa.
2. Digital telephones with RCPI-Dls or PDIU-
Dls that must access modems from a
pool require a Modem button assigned
in Program 39.
3. PDIU-DS ports that are connected to
modems in the modem pool should be set
with LEDs 01, 02, 03, and 04 in Program
20.
4. If a modem connected to PDIU-DS is
connected to a telephone network line
instead of a standard telephone station
port, Program 21 should not be used.
5. Use Program 22 to assign modem/PDIU-
DS stations to hunt sequences.
6. DlUs can be connected to ports
associated with PDKU 1 Circuits 1 - 7
only. All PDKU2 circuits, I - 8, can
support RPCI/DIUs. RDSU Circuits 5 - 8
can support RPCI/DIUs.
.Program 22-Computer Interface Unit (RPCI) and
Data Interface Unit (DIU) Station Hunting
If a RPCVPDIU station (printer, modem, etc.) is busy,
data station hunting allows the data call to that station
to hunt to an alternate RPCIIPDIU station assigned in
this program. If the hunted RPCVPDIU station is busy,
the system will ring the next "hunt-to" station, and so
on. If all RPCVPDIU stations in the "hunt-to" sequence
are busy, then the data caller will receive a busy tone.
It is recommended that all PDIU-DS station ports
grouped in a modem pooling or printer pooling/server
configuration be placed into a hunt-sequence
arrangement with Program 22. Program 22 applies to
PDIU-DS and RPCI-DI/PDIU-DI data calls, not
telephone stations voice calls.
Note:
When a PDIU-DS is connected to a modem(s)
assigned to the system modem pool in
Program 21, modem hunting is automatic
when the user presses the Data Call
(DATA) button to transfer a line call to a
modem; however, if the user dials the
modem's PDIU-DS's station number, modem
hunting will follow th,e hunt sequence
specified in Program 22.
Programs 23 and 24-Built-in Auto Attendant
Announcement Device Assignments
Assign customer-supplied Auto Attendant
announcement devices (digital announcers) to
standard telephone ports (RSTU, RSTU2, PSTU,
PESU, RDSU/RSTS) with these programs. Devices
which will deliver primary announcements-dialing
options and greeting heard when callers first call in-
should be assigned in Program 23, and devices which
will deliver secondary announcements-typically
options offered to unanswered calls routed back to the
Auto Attendant-should be assigned in Program 24.
As many as eight devices can be connected to'a
system, a maximum of four for primary
announcements and a maximum of four for secondary
announcements.
Notes:
1. Any combination is allowed within the
maximum limitations. For example, three
primary announcements and one
secondary announcement are allowed.
2. Ports assigned in Programs 23 and 24
should never be assigned with External
Auto Attendant voice mail options in other
programs (30, 3 1, 8 1 - 89, etc.)
Program 25-1 -Incoming Built-in Auto Attendant
Call Overflow Time
Sets the time it takes an unanswered incoming Auto
Attendant call to overflow toss preassigned station or
stations. The time can be anywhere from 12 to 24
seconds-the default is 20 seconds. The overflow
