3.8 INSTALLING emaGEN VOICE MAIL CARDS 
IN THE emaGEN-PC
3.8.1emaGEN voice mail card jumper settings
One or more of the following three types of 
emaGEN-PC four tele-
phony port, single slot, half-sized, ISA compatible voice processing 
cards, manufactured by Brooktrout Technology, are used, in order to 
set up your system. 
Depending on which of these cards are to be used in your system, 
refer to  the corresponding Brooktrout Technology Hardware instal-
lation Guide brochure:
 Prelude Quartet card -- Part Number 934-011-40, Revision 1.00;
 Vantage Volare card  -- Part Number 934-009-90, Revision 1.00;
 RDSP 432 card         -- Part Number 73-00-0014, Revision 1.00.
You should comply with all instructions in the brochure before insert-
ing the respective type of 
emaGEN-PC card into the emaGEN-
PC.
The Quartet board has fixed settings as card no. 1, for which no 
juper setting is required. For junper settings of all other cards, follow 
the required jumper settings shown in Table 3-1, below, for each of 
the respective cards. In this table: O = open circuit X = closed cir-
cuit.

3.8.2
emaGEN-PC voice mail card insertion
You must insert the 
emaGEN-PC cards into the emaGEN-PC.  
Cards can be placed in any PCI slot.
WARNING
Turn off and disconnect power to the PC,
before starting any card insertion proce-
dure.
The physical act of installation is the same as for any  other PC card. 
This procedure is not described here, since it may vary from one PC 
model to another. Refer to your PC manual for card installation 
instructions.
CAUTION
The 
emaGEN-PC printed circuit cards
contain components that are sensitive to
static electricity and should not be handled
except as needed to avoid any problem
with electrostatic discharge. Hold the card
by its outer edges. The use of a wrist
ground strap is recommended, as shown in
Figure 3-1, below.

3.9 SYSTEM PREPARATION AND CONNECTIONS
TO emaGEN
3.9.1 Mounting an MIM on an OCD card
Figure 3-2, below, shows the three module positions on the OCD 
card. Each OCD card can accommodate up to three cartridge mod-
ules, each serving a special option function. 
You must connect one MIM (multiple interface module) on the OCD 
card for each group of four 
emaGEN ports to be connected to the 
card. The MIM connects the voice channels to the 
emaGEN-PC.
An 
emaGEN system of up to 12 voice mail ports can be handled by 
one OCD card. However, a 16 port voice mail system requires four 
MIMs, which necessitates two OCD cards. For a system of between 
five and 12 ports you can, if you choose, take advantage of the Mul-
tiple Communication Ports feature and balance system load (espe-
cially if the system includes SMDR) and improve system 
performance by placing MIMs on two different OCD cards, as 
described in Section 3.9.3, below.
You can select any positions on the OCD cards for the MIMs. If you 
require two OCD cards, for example, you can put two MIMs on each 
card; or you could put three MIMs on one card and the fourth on the 
second.
1. You must appropriately program the 
unite system, as described 
in configuration programming covered in Section 19, below, to 
match the selected MIM position(s).

2.  You then assign voice channel and DN numbers to the ema-
GEN
 ports. 
3. Lastly, you physically connect 
emaGEN-PC cards, via the 
audio cable, junction box, and MDF, to the audio channels of the 
OCD card MIM(s).
To mount the MIM on the OCD card, perform the following steps, as 
shown in Figure 3-2, below:
1. Place the OCD card on a soft, clean surface (a piece of sponge 
or cardboard) with the components facing up.
2. Select the position in which the MIM is to be attached to the 
OCD card:
 3, the upper position, with 20 and 64-pin connectors 
J6 and J9, respectively;
 2, the middle position, with 20 and 64-pin connectors 
J5 and J8, respectively;
 1, the lower position, with 20 and 64-pin connectors 
J4 and J7, respectively.
3. Plug the MIM into the selected pair of 20 and 64-pin connectors.
4. Make sure the module is seated firmly against the OCD card.
5. Tighten the screw on the top of the module.
NOTE
The position in which the MIM is assigned
and mounted on the OCD card determines
which voice channels and which wires will
be dedicated to it for connection between
the 
emaGEN-PC and the unite system
cabinet.

3.9.2 Inserting an OCD card into the system cabinet
To insert an OCD card in one of the 
unite system cabinet slots, 
perform the following steps, as shown in Figure 3-3, below:
1. With the two plastic extension tabs on the end of the OCD card 
extended outwards, slide the card into the guide runners of the 
selected slot.
2. Carefully fit the card into the V-shaped insertion guides.
3. Ensure that the female connector on the card is aligned with its 
male counterpart on the system cabinet backplane.
4. Place both thumbs on the plastic tabs and press the card firmly 
into place.
5. Fold the tabs flat against the card until they snap into place.
Each OCD card is connected to the MDF by means of a 25-pair 
cable. This cable is standard for all cards in the 
unite system, as 
described in the 
unite family of systems Installation manual.

3.9.3 Completing the data connection
The first 
emaGEN card in the emaGEN-PC connects, as 
described below, directly to the OCD card in the 
unite system cab-
inet, by means of the RJ45 connector located at the end of  the OCD 
card. If two, or more, 
emaGEN-PC cards are installed, you connect 
only the first 
emaGEN-PC card, card number 1, to the OCD card. If 
four, or more, 
emaGEN-PC cards are installed, you must connect 
the fourth, or last, 
emaGEN-PC card to the second OCD card. 
If you choose, for a system of between five and 28 ports, as 
described earlier, to take advantage of the Multiple Communication 
Ports feature by placing MIMs on two different OCD cards, there 
must be a data cable connection between the last 
emaGEN-PC 
card and the second OCD card as well.
NOTE
If your system has two, or more, OCD
cards, it is recommended that you also con-
nect the second, or last, OCD card to the
emaGEN-PC card assigned the ports
operating the SMDR features. This will
divide the communication load between the
emaGEN-PC and the two cards.

The emaGEN-PC card connection to the OCD card is by means of 
a cable, shown in Figure 3-4 terminated by:
 A 9-pin D-type female connector on the 
emaGEN-PC com port;
 An RJ45 male connector on the OCD card end of the cable.

emaGEN-PC card must have an audio connection to the 
unite system. It is connected to an OCD card, as shown in Figure 3-

Figure 3-5   emaGEN cabling from emaGEN-PC to OCD card
Note in the Figure 3-5, that:
 Connector J3 on the 
emaGEN-PC card connects to the OCD 
card containing the MIM by means of a cable, shown in Figure 3-
6, terminated by an RJ11 connector on both ends.
Each of the terminal pairs in the junction box is connected, via a 
pair of wires, as shown in Figure 3-6, to the audio terminals in the 
MDF of the corresponding voice channel utilized as an 
ema-
GEN
 port.
 A standard 25-pair cable, or cables, used to connect the OCD 
block in the MDF to each OCD card in the 
unite system cabinet, 
will then also make the final connection of  the  corresponding 
emaGEN ports.
This information should assist the installer in selecting the MDF ter-
minals to which each 
emaGEN audio port from the junction box is 
to be wired.

3.10 ADDITIONAL STEPS BEFORE ACTIVATING emaGEN
Although you have made all the required physical connections 
between the 
emaGEN-PC and the unite system, you are not yet 
ready to activate 
emaGEN. You must now carry out the following 
steps:
