An Avaya Modular Messaging system supports up to 3 D/480JCT-2T1
QSIG boards, or up to 2 D/600JCT-2E1 QSIG boards. For more information
about installing either of these Dialogic DualSpan boards, see D480-600JCT
(pdf).
To set the jumpers for a new or replacement QSIG board:
- Set the unique board ID for the new card. Turn the SW100
rotary switch, located on the top of the card, to set the board
ID according to the slot in which you are installing it.
Dialogic port boards should be placed in the PCI slots starting
from the rightmost side of the cabinet. For an Avaya MAS, the
board IDs would be:
- The card in PCI slot 6 is assigned ID 0.
- The card in PCI slot 5 is assigned ID 1.
- The card in PCI slot 4 is assigned ID 2. (This slot would
be used only for a D/480JCT-2T1 QSIG board.)
- If more than one card is installed in the system, set up the
boards on either end of the Computer Telephony (CT) bus for bus
termination. Use the P700 jumper to set CT bus termination
as shown in the following table:
| Number of cards |
P700 jumper |
CT bus termination |
|
1
|
OFF |
bus not terminated |
|
2
|
ON pins 3 and 4 |
terminate bus on both boards |
|
3
|
Card 1: ON pins 3 and 4
Card 2: OFF
Card 3: ON pins 3 and 4 |
terminate bus on the end boards
(3 cards are present only if the MAS uses D/480JCT-2T1 boards)
