Comdial Execumail Voice Processing System 6.5 Instructions Manual

Installation Manual Voice Board Technical Reference 4 7 
You can distinguish between a Z-port voice board (D/21) and a 4-port board 
(D/41) by examining the layout of electronic components on the circuit board. 
The components on a drport board are laid out in groups of four. The 
components on a 2-port board, however, are laid out in pairs, and the circuit 
board. has fewer components than a 4-port board.

The interrupt level (also called interrupt vector or interrupt number) assigned to 
a hardware device tells the computer which time slice to use for communicating 
with that device. The interrupt level also tells the device when to expect to 
communicate with the computer. 
If different kinds of devices are assigned the same interrupt, the computer won’t 
be able to tell the devices apart and will not function properly. Similarly, if a 
device is assigned...

The voice mail installation program will set up the system to use the following 
addresses: 
A000AFFF Reserved for VGA 
D000DFFF Voice boards 
E000-EFFF EMS Page Frame 
If this configuration does not work on the computer, you will need to change the 
base memory address of the voice boards and/or the page frame. The voice 
board settings are described in this section.

Notes on the Voice Board Dip Swikh and Jumpers 
Interrupt Level [JPI] 
The JPI jumper controls the voice board’s interrupt level, 
from level 2 through level 7. The default setting on the 4th 
pair of pins from the left sets the voice board to use 
interrupt level 5. (See figure.) Setting the jumper to connect 
the first pair of pins from the left sets the voice board to 
use interrupt level 2; setting the jumper to connect the 
second pair of pins...

‘First Board” Jumper [JP7] 
The JP7 jumper identifies which voice board in the system is the “first board” in 
the system. The first board has Port #l and has the first memory address that the 
system looks for. 
Only the first voice board in the system should have JP7 on. 
l These settings apply to the fmt voice board only.

Notes on Command Line Parameters 
If you change any of the default settings for the voice boards’ dip switch or 
jumpers, you may need to change the way the voice mail software is started and 
run. This is done by using special command line parameters (-S###, -A###, 
and -I##), whenever you start the voice mail system. These are entered in the 
appropriate line of the VM.BAT file used to...

Sfarting Memory Address for Voice Boards 
kS####] 
If you change the default settings for the JP5, JP6 jumpers or the SW1 dip switch, 
you may need to start the voice mail software with a new memory address 
parameter. If there are no command line parameters entered, the system software 
expects to find the first voice board’s memory address at DOOO. If the first voice 
board’s memory address is at another D address (for example, D200), or if any 
voice...

G _ In this example, you must set the jumpers and dip switches on three of the 
boards to be in the first three addresses in the C segment, and the jumpers and 
dip switches on two of the boards to the first two addresses of the D segment. 
YOU should contact Comdial Technical Support before attempting this sort of 
configuration.

If you are experiencing false pause off, we recommend that you try setting the 
silence threshold to 45dB as a first step. 
To set a DSP board to 45 decibels: 
1. 
From the back of the computer, check that the board is a DSP board. DSP 
boards have a gold sticker saying “DSP” near the modular jacks.
