You can install an OC-3c/STM-1, an OC-12c/STM-4 or a 155
Mbps-over-UTP5 daughter card in either the right pair or the left pair of
cutouts of the ATM Interface Carrier Module (Figure 2). However, if you
are installing a single card, 3Com recommends installing it in the left
cutouts, which are shipped uncovered for this purpose.
