neously to release the card from the internal connector, th en s li de the card carefully out from
the rear of the AB2 chassis (see Figure 8-2).
3. To set different transmit and/or receive gain or loss levels, refer to Figure 8-1 and Table 8-1.
4. To reinsert the FXS-ID voice card, ensure that the card is positioned correctly in the card
rails, then carefully slide the card into the slot until it stops.
5. Press both card ejector latches in towards the FXS-ID card to seat the 64-pin DIN connector
in the matching connector on the internal Controller card.
6. After setting the transmit and receive level options, replace the back plate and tighten the
thumbscrews.
