Strata CTX I&M September 2002
Universal Slot PCBs
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 categorised as station, Exchange line or option PCBs (see Tables 1-9~1-11). Feature
subassemblies that plug onto a universal slot PCB, such as the Standard Telephone Interface
Subassembly (RSTS), are listed below the associated PCB.
