Installing the Hardware Step 3: Configuring the Voice Boards
Octel 50 Installation Guide 3-5

Configure for multiple boards
Setting the board’s base shared memory address–The base shared memory address
allows the voice board to communicate with the voice driver and, in turn, the Octel 50
system. SW1 determines the Dialogic board’s base shared memory address.
If you are only installing one Dialogic board, leave SW1 at the default setting unless it
conflicts with another component. If you are installing multiple boards or there is a conflict,
you can change the base shared memory address by configuring the first three jumpers
on SW1.
The following figure illustrates the recommended jumper settings for the boards. The first
column lists the board number, the second column lists the base shared memory address
that should be assigned to each board, and the third column represents the jumper
settings that correspond to the base shared memory address.
Modifying the board’s base memory segment–The shared memory block on the PC is
called a segment. You can set most Dialogic boards to an address in the D segment,
which is the default. If you cannot use the D segment due to a conflict or for some other
reason, a technical support representative can advise you to use an address in segment
A or C.
To use an alternate segment, you must install one of two jumpers on the Dialogic board:
•
Install the JP5 jumper if you assign the voice board an address using the A
segment, such as A0000.
•
Install the JP6 jumper if you assign the voice board an address using the C
segment, such as C0000.
Do not change the settings of either of these jumpers unless a technical support
representative directs you to set the voice board to an address using an alternate
segment.
Setting the board’s hardware interrupt–The JP1 jumper block sets the Dialogic boards’
hardware interrupt level, also called the IRQ. Interrupt settings for these boards range
from 2 through 7. Install the jumper that corresponds to the interrupt level you want to
use. You must set all Dialogic boards to the same interrupt level. The recommended
interrupt is IRQ5. Depending on the system configuration, you may have to try different
interrupts before you find one that does not conflict with other devices.
The interrupt levels typically assigned to standard computer components are as follows:
IRQ3 = COM2
IRQ4 = COM1
IRQ5 = LPT2
