Shelves
Shelves house the common equipment and channel units. The shelf backplane supplies the bus
connectivity for provisioning the common equipment and channel units.
Coastcom D/I Mux III multiplexers include the following shelf types (see Figure 1-8).
•
D/I Mux III, 8-slot with 8 line card slots and 2 T1 transmission ports
•
D/I Mux III, 12-slot with 12 line card slots and 2 T1 transmission ports
•
D/I Mux III, 24-slot with 24 line card slots and 2 T1 transmission ports
The number of slots (i.e., 8, 12, and 24) refers to the number of slots available for installation of line
cards after the common equipment has been installed. Common equipment, such as the CCU, AMCU,
and LIUs, do not occupy any of the 8, 12, or 24 slots.
The three shelves accommodate the same common equipment and line cards (except the 12-slot, which
will not accept the now obsolete 30308-102A AC/DC power supply, due to physical layout of the shelf).
All D/I Mux III shelves include an Electrostatic Discharge (ESD) strip located at the base of each card slot. The
ESD strip protects data transmission from errors caused by electrostatic discharge. The ESD strip is labeled, or
silk-screened, with the correct common equipment component name for that particular slot.
