FAX Installation Guide P0886634 Issue 1.0
Installing the DFC in the NAM
1. Ground yourself by attaching one end of the grounding strap to your wrist and
the other end to a grounded metal surface.
2. If you have a NAM II, locate slot 8 on the expansion bus. If you have a new
NAM, locate slot 1 on the expansion bus. Remove the slot cover screw and
the metal slot cover from the slot. Keep the metal slot cover and screw. You
will have to re-install the metal slot cover if you remove the DFC.
3. Switch SW1 should be set according to the following table:
4. Switch SW2 should be set according to the following table:
5. Ensure there is a jumper on position 10 of the INTERRUPT.
Note: The settings in these table are the default values and should be set
properly when the board is received. Refer to Figure 12
on page 17 for
the location of the switch SW1, SW2 and the INTERRUPT jumpers.
6. Carefully hold the DFC along the top only. Insert the card by aligning
between the metal groove on one side and the slot opening on the other side.
7. Push the DFC straight in until it is snugly in place. Ensure the edge connector
is firmly inserted into the socket.
8. Fasten the slot cover screw in the DFC slot cover.
Connecting the DFC to the BIC with the PEB Cable
There are no fiber connections to the DFC. The DFC uses the voice ports on the BIC
to connect the fax ports to fax machines or a call.
Only one DFC can be installed in a NAM. The DFC connects to the BEC
daughterboard attached to the BIC through the PCM Expansion Bus (PEB) cable.
This cable must be connected from the DFC to the BIC. The PEB cable connects
the DFC to the BIC to share the ports connected to the Norstar KSU.
