Setting the Initial Hook Switch State (SW1:4)

SW1 switch 4 (SW 1:4 in Figure 2) sets the initial hook
switch state for the D/41D and D/21D board. This
setting is active only when the PC is powered on but the
firmware has not yet been downloaded to the board.
If the initial hook switch state is set to on-hook (default)
the board presents an inbound call with a ring no answer
state. You can change the initial hook switch state to off-
hook to present a busy signal instead.
Once the firmware is downloaded, the hook switch state
is set to on-hook, and may only be changed by the
application controlling the board.
It is not necessary to set all D/41D or D/21D boards in
the system to the same default hook switch state.

Note: If the PC is not powered on, the inbound call
response is ring no answer when a board receives a call.

Configuring the Line Source (JP8)

The D/21D and D/41D boards can send and receive
audio signals through a built-in loop start interface (J1
and J2) or an external interface through the AEB (P3).
Select the line source with JP8 (see D/41D Physical
Description) as follows:
Line Source JP8

Increasing Ring Detection Threshold Behind

a PBX (JP101–JP401)

If a board has problems detecting rings behind a PBX,
you can lower the ring detection threshold. To lower the
threshold on a channel-by-channel basis, install the
jumpers JP101–JP401 (see D/41D Physical Description)
as follows:
Channel 1
Channel 2
Channel 3
Channel 4
Jumper JP101
Jumper JP201
Jumper JP301
Jumper JP401
Note: A lower threshold may be too sensitive for
boards connected to the CO and cause false detection of
rings.
Installing the Hardware
1. Prepare a static-safe work area, turn off all power to
the system, and disconnect the system’s power cords
from electrical outlets.
2. Remove the PC cover.
3. Select an empty ISA expansion bus slot, and remove
the slot’s retaining screw and access coverplate.
4. Insert the board’s edge connector into the bus slot.
5. Replace and tighten the retaining screw.
Select a new slot and repeat steps 3–5 for each board
you are installing. Use an AEB cable to connect this
board with other boards (for example, Dialogic AMX/81
or DTI/124 T-1) in the system. Reinstall the PC cover
when finished.

Make the Connections

n The D/21D supports one channel per RJ-14 jack.
The D/41D supports two channels per RJ-14
jack.
n You can use an RJ-11 connector with the D/21D.
If you use an RJ-11 connector with the D/41D,
only the channel connected to contacts 2 and 3 of
the board’s RJ-14 jack can be accessed.
n Connect one end of a terminated cable into the
RJ-14 jack on the board and the other end into a
wall jack. One terminated cable is required for
each jack.
n A standard telephone will not function when
directly attached to the board’s RJ-14 jack.

After Installing the Hardware

n Install the voice board software as described in the
documentation provided for the Dialogic software
release and operating system in use.
n Test the boards using D40CHK.EXE or other
diagnostic utilities such as UDD (Universal
Dialogic Diagnostics) that came with the Dialogic
software release for the D/41D and D/21D.
n

Warranty Period
The D/41D and D/21D boards have lifetime warranties.
See the Hardware Limited Warranty card for coverage
details.
RMA Process
If you suspect you have a problem board, you can return
the board to Dialogic for servicing. The following
outlines the procedures that make up the Return
Material Authorization (RMA) Process.
1. Check to see if the problem is due to a mistake or
oversight in the installation process. Be sure to run
the diagnostic utility if you have not already done so.
2. Call Dialogic Technical Support at 1-973-993-1443
to confirm that it is a problem board.
3. Call the RMA coordinator at 1-973-993-3000 x6374.
Telephone lines are open from 9 a.m. to 5:30 p.m.
EST. Give the board’s serial number (two letters and
six digits—located on a label attached to the board)
and a brief description of the problem to the RMA
coordinator. The RMA coordinator will give you an
RMA number and an estimated return date.
4. While observing correct static-handling procedures,
disconnect power, cables, and remove the board from
the chassis.
5. Repack the board, observing correct static-handling
procedures. Place the board in an anti-static container
and then put it in a shipping carton using appropriate
packing material. Use the original shipping materials
if possible. Include diagnostic printouts (for example,
D40CHK) when applicable.
6. Write the RMA number on the outside of the box
you are shipping (for example, RMA #2973) and
send the package to the attention of the RMA
number assigned.
7. Ship the board to Dialogic at the following address.
