Settings for Dialogic analog boards

An Avaya Modular Messaging system supports the following Dialogic analog port boards:

• D/120JCT-LS 12-port analog boards (maximum of 4). See the Dialogic file D120JCT-LS (pdf) for details.
• D/41JCT-LS 4-port analog boards (maximum of 2). See the Dialogic file D41JCT-LS (pdf) for details.

To set the jumpers and switches for a new or replacement board, see the appropriate section:

• Settings for D/120JCT-LS 12-port analog boards
• Settings for D/41JCT-LS 4-port analog boards

Settings for D/120JCT-LS 12-port analog boards

To set the jumpers and switches for a new or replacement D/120JCT-LS 12-port analog board:

1. 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.
   • The card in PCI slot 3 is assigned ID 3.
2. Set the hook-switch state of the new card to ON so that callers hear a busy signal when the card is not initialized. Use the SW1 switch, located at the top of the card, to set the hook-switch state. See Setting a Dialogic analog board on-hook switch.

Settings for D/41JCT-LS 4-port analog boards

To set the jumpers and switches for a new or replacement D/41JCT-LS 4-port analog board:

1. Set the unique board ID for the new card. Turn the SW30 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.
2. Set the hook-switch state of the new card to ON so that callers hear a busy signal when the card is not initialized. Use the red SW4 switch, located near the top of the card, to set the hook-switch state. See Setting a Dialogic analog board on-hook switch.
3. If more than one 4-port board is installed in the system, set up the boards for Computer Telephony (CT) bus termination. Use the JP2 jumper to set CT bus termination as shown in the following table:

Number of cards	JP2 jumper	CT bus termination
1	OFF	bus not terminated
2	ON pins 1 and 2	terminate bus on both boards




See Setting D/41JCT-LS board CT bus termination.
