Figure 9-3: BRFXS/DPO Transmit and Receive Level Options

If your voice channels require different attenuation level settings than the factory defaults, proceed as follows:

Caution: Use proper electrostatic discharge (ESD) procedures when removing and handling the analog cards.

1.Release the two thumbscrews on the ABI back plate and remove the plate.

2.Pull out the two card ejector latches simultaneously to release the card from the internal con- nector, then slide the card carefully out from the rear of the ABI chassis.

3.Set different transmit and receive gain or loss levels (see Figure 9-3and Table 9-1).

4.Re-insert the BRFXS/DPO voice card, ensuring that the card is positioned correctly in the card rails.
