4.06 Miscellaneous Equipment. The Floppy Disk Drives 
(FDDs) are data storage modules which use a 5- l/4 inch flop- 
py disk as the data storage medium. The double-sided, quad 
density, removable disk is not shipped with the FDD module and requires compliance with certain licensing agreements 
prior to its delivery. Refer to Table 4.12 for further details on 
the FDD modules.

4.07 Printed Circuit Boards. The plug-in PCBs are 230mm 
(9.02 in.) high by 280mm (11.02 in.) deep. Each PC6 has two 
edge-connector tab areas with 60 terminals each. The PCBs 
plug into mating 60-pin connectors mounted on the backplanes 
of the basic and LTU shelves. Two extractor levers, mounted on 
the faceplate of each PCB, allow for easy insertion or removal 
from the shelf connectors. Each PCB comes factory-shipped in- 
side an anti-static bag to protect...

Table 4.13 Dual-Tone Multifrequency (DTMF) Receiver PCB (S30810-(2431-X2- * -B900) 
DESCRIPTION The DTMF PCB, shown in Figure 4.27, contains four circuits (0, 2, 4, and 6) utilizing four ports. Under 
no circumstances should more than three DTMF receiver cards be assigned on one shelf. This require- 
ment is a limitation of the power supply. Each circuit provides the means for dial tone detection and 
validation of DTMF...
