General
Cl.01 This Appendix details the cabling and cross-connections re-
quired when installing the SX-lOO/SX-200 system.
Telephone Set and Trunk Cabling
Cl.02 Telephone set and trunk cabling terminates on the building
cross-connection terminal in the normal manner. The cabling
requirements and limits for stations and consoles are shown in Figure
Cl-l(a) and (b).
Cable Terminations, SX-100
Cl.03 All interconnecting cables must be terminated in accordance
with Tables Cl-l, Cl-2 and Figure Cl-2.
Cable Terminations, SX-200
Cl.04 All interconnecting cables must be terminated in accordance
with Figure Cl-3 and Tables Cl-l, Cl-2, Cl-3 and Cl-4. In
addition, if Shelf 2 is installed, the interconnecting cables listed in
Table Cl-4 must be terminated.
Cross-Connections
Cl.05 Jumpers should be run using Z-type 24 AWG cross-connecting
cables or equivalent.
Cl.06 Connection between the equipment cabinet, cross-connect
field, stations, trunks and consoles should be made using 26
AWG connector-ended cable in accordance with Tables Cl-l through
Cl-4.
Cl.07 Cabling connections between Shelf 1, the interconnect board
and cross-connect field are shown in Figures Cl-3 and Cl-7.
Cl.08 Figures Cl-4 and Cl-5 illustrate typical block and -wiring did-’
grams for a power fail transfer circuit. Figure Cl-6 illustrates
typical night bell wiring connections and Figure Cl-7 shows the con-
nections for music and PA requirements.
