Configuring an analog-line interface card

Complete the following procedure to configure an analog-line interface card. Use the analog-line interface card diagram as a guide when configuring a card.
  Warning! Damage from electrostatic discharge is possible. See Protecting against ESD damage for more information.

To configure an analog-line interface card:

1. Remove the new card from its packaging.
2. Set the unique board ID of the new card. Turn the SW30 rotary switch, located on the top of the card, to change the board ID.
   • If you are replacing an existing card, verify that the ID of the new card matches the ID of the card that you removed by comparing the old card with the new card.
   • If you are adding a new card, set the board ID according to the slot in which you are installing it. Analog-line interface cards are placed in the slots numbered PCI 3 through PCI 1, from bottom to top. See the Internal view of platform for slot location. Board IDs are assigned as follows:
   • The card in PCI slot 3 is assigned ID 0.
   • The card in PCI slot 2 is assigned ID 1.
   • The card in PCI slot 1 is assigned ID 2.
3. Verify that the hook-switch state of the new card is set 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. If you are replacing an existing card, verify the setting by comparing the old card with the new card.
4. If more than one card is installed in the system, set the CT Bus jumper. Use JP2 to set the CT Bus jumper.
5. If you are replacing an existing card, verify that the CT Bus jumper setting is the same as the card you removed by comparing the old card with the new card.
6. If you are installing a new card, use the following table to determine whether the CT Bus should be jumpered to terminate the CT Bus jumper.

   CT Bus Jumper Settings Table

   Number of Cards	CT Bus Jumper Setting
   1	Off (not jumpered)
   2	On (both pins jumpered)
   3	On (both pins jumpered) for the first and third cards (PCI slots 1 and 3); Off (not jumpered) for the middle card (PCI slot 2)



7. Install the new card in the PC.
