3. PHYSICAL DESCRIPTION
A. SX-100 Equipment
.
2.04 SX-200 consists of a single cabinet (containing the switching
circuitry and the system power supply) and a desk-type atten-
dant console equipped with pushbutton dial pad and control buttons.
2.05 Connections between the equipment, the consoles and the dis-
tribution frame are made using connectorized 25-pair cables.
2.06 Noiseless operation, exceptionally small size and environmental
tolerance allow a wide choice of locations for the equipment.
Maintenance
2.07 The modular design and functional packaging of the equipment
systems permit rapid location and replacement of defective
equipment. Circuit malfunctions are detected by diagnostic routines
automatically initiated by the CPU. These circuit malfunctions will ap-
pear in the console's SOURCE or DESTINATION display when the
ALARM RESET is pressed. The diagnostic routines which are detailed in
Section MITL9105/91
tion, and the use of Section MITL9105/9110-090-350-NA,
shooting Manual, direct service personnel to the defective circuit card
or assembly, and indicate the required field-replaceable unit. Diagnos-
tic routines and maintenance procedures do not interfere with users
not affected by the malfunction.
2.08 System expansion is achieved by the addition of plug-in line
and trunk printed circuit cards. Lines are added in increments of
eight, CO trunks are added in increments of four and Tie trunks are
added in increments of two.
