An S3400-family Avaya MAS supports up to four (4) universal-type
D/82JCT-U Digital Set Emulation (DSE) Dialogic boards, depending
on the TUI. For systems that were upgraded from Release 1, up to
five (5) DSE boards might be present in an MAS with a nonintegrated
video and LAN, if five DSE boards were installed before the upgrade.
For more information about installing DSE boards, see the Intel
Dialogic document D82JCT-Univ
(pdf).
Note: The Dialogic documentation describes more setups than
the ones used for Avaya Modular Messaging. If information in a Dialogic
document conflicts with an Avaya document, follow the steps in the
Avaya documentation. You can use the Dialogic documentation to locate
various items on the board or verify cable connections.
Two types of DSE port boards can be present in an S3400-family
MAS:
- Dialogic D/82JCT-U — can use only a 5V bus
- Dialogic D/82JCT-U-PCI-UNIV — universal board that can
use either a 5V or 3.3V bus
|
Caution!
The older model of MAS motherboard for the nonintegrated video
and LAN configuration contains six 32-bit, 5V port board slots.
The new model of MAS motherboard for the integrated video
and LAN configuration has three 64-bit, 3.3V universal port
board slots, and only one 5V port board slot. If you have
an older model of 5V port board that is not universal
and does not fit the 64-bit, 3.3 V PCI slot, you can install
only one port board into a later model of S3400-family MAS.
The Avaya replacement strategy is:
- Avaya ships only the universal model of DSE port board
for new servers and as field replacement units.
- If an Avaya MAS must be replaced, Avaya replaces the faulty
server with a one that uses the same type of motherboard.
Therefore, the different number of 5V port board slots between
servers is not an issue.
Note: The model of DSE port board is not an issue
for upgrades to an Avaya S3500-family MAS. The port board
slots in the PCI card cage for an S3500-family server use
a 5V bus.

To set the jumpers for a new or replacement DSE board, you must
set only the bus termination:
If more than one port board is installed in the server, set the
boards on both ends of the Computer Telephony (CT) bus for bus
termination. Use jumper P8 to set CT bus termination as
shown in the following table:
| Number of cards |
P8 jumper |
CT bus termination |
|
1
|
OFF |
Do not terminate bus. |
|
2
|
Card 1: ON pins 1 and 2
Card 2: ON pins 1 and 2 |
Terminate bus on both boards. |
|
3
|
Card 1: ON pins 1 and 2
Card 2: OFF
Card 3: ON pins 1 and 2 |
Terminate bus on boards 1 and 3. |
|
4
|
Card 1: ON pins 1 and 2
Card 2: OFF
Card 3: OFF
Card 4: ON pins 1 and 2 |
Terminate bus on boards 1 and 4. |
|
5
|
Card 1: ON pins 1 and 2
Card 2: OFF
Card 3: OFF
Card 4: OFF
Card 5: ON pins 1 and 2 |
Terminate bus on boards 1 and 5.
Note: 5 cards can be present only in an MAS with a
nonintegrated video and LAN. |

bus termination.
