Universal Slot PCBs4
Universal Printed Circuit Boards (PCBs) installed in the Strata CTX100 or CTX670 cabinets 
provide interfaces for stations, lines, and peripherals. Each PCB measures 7.5 x 5.5 inches (190 x 
140 mm) and mounts in the slot with a 44-pin backplane connector. PCB external connections to 
station equipment are made to the Main Distribution Frame (MDF) using industry-standard 
connectors.
Station, Line and Option PCBs
The PCBs are categorized as station, CO line or option PCBs (see Ta b l e s  1 4~16). Feature 
subassemblies that plug onto a universal slot PCB, such as the Standard Telephone Interface 
Subassembly (RSTS), are listed below the associated PCB. For further details, refer to the Strata 
CTX I&M Manual.
