Dialogic Digital Network Interface Board DN/I601TEPHMP - Manual (Page 2)

Setting Power-off Default Front End
Loopback
When the system shuts down (powers off), the
board enables analog loopback to the connected
trunk line(s). Factory default setting is enabled for
each trunk (jumper clips are installed). To disable,
remove the pair of jumper clips for the desired
trunk(s).
The following table lists each pair of jumpers and the
corresponding trunk. Refer to the Physical Layout
figure for the location of the jumpers.
Setting Boot Up Default Front End
Loopback
When the system is started or restarted, the board
enables analog loopback to the connected trunk
line(s) and provides digital loopback to the board.
Factory default setting is enabled (jumper clip is
removed). To disable, install the jumper clip. Refer to
JP5 in the Physical Layout figure.
3. Installing the Board
CAUTION: These procedures assume familiarity
with the general terminology associated with
electronic equipment and with the safety practices
and regulatory compliance required for using and
modifying electronic equipment.
These procedures should be performed only by
qualified technical personnel.
WARNING! Unplug the equipment before
performing the procedures described here.
Failure to disconnect the power before you open
the chassis can result in personal injury. Ensure
that the system is disconnected from its power
source and from all telecommunications links,
networks, or modem lines whenever the chassis
cover is removed. Do not operate the system
with the cover removed.

CAUTION: To avoid possible damage to the board,
remove power from the computer before beginning
installation. Observe proper anti-static precautions
at all times while handling and installing the board.
Note: It is recommended that you install the
hardware before installing the software.
Install the board as follows:
1. With your computer at a static-safe work area,
switch off the power and disconnect the power
cord.
2. Remove the computer cover.
3. Select an empty PCI expansion bus slot and
remove the slot’s retaining screw and coverplate.
4. If you are installing your board in an ISA form
factor PCI slot, optionally install an ISA edge
retainer on the board.
5. Using the slot’s board guides, insert the edge
connector of the board into the bus slot. Press
firmly until the board is securely seated in the
slot.
6. Replace and tighten the retaining screw to
secure the board firmly in the bus slot.
7. Repeat steps 3–6 for each board you are
installing.
8. If appropriate, use an optional CT Bus cable to
connect the board(s) you are installing to other
boards in the system. To preserve the electrical
integrity of the CT Bus, use a CT Bus cable with
the appropriate number of connectors (“drops”).
It is recommended that no more than two
connectors at either end of the cable be left
unused. For boards located at each end of the
CT Bus cable, be sure to set bus termination
appropriately as described in the Setting CT Bus
Termination section.
9. Replace the computer cover when finished and
reconnect the power cord.
10. Turn on the power to the computer.
Note: If your BIOS is set to use Plug and Play
technology and there are ISA boards in your system,
an IRQ conflict can occur if your PCI board is
assigned the same IRQ as an ISA board. This can
cause the machine to stop responding. To prevent
this conflict, enter the BIOS and reserve the
appropriate IRQs (those used by your ISA boards)
for ISA use only.
4. Connecting to External
Equipment
Connect the RJ-48C jack on the board bracket to the
switch using a digital T1 or E1 crossover cable. If
you are building your own cable, you should be
familiar with the connector pin designations for the
RJ-48C jack.
