Overview
The COMSPHERE 3000 Series Carrier is a metal

other sixteen slots are for devices. This number is reduced
by one slot for:
Dial/lease multiport modems, which occupy two
slots.
DSU with MUX card. The MUX card for TDM or
MCMP is physically attached to a DSU, and the
two cards occupy two slots.
Digital bridge applications, where each DBM-X
also occupies a separate slot.
