Strata CTX670 Cabinet Slot Configuration
The cabinet diagram below enables you to write in the PCBs installed in each cabinet slot. Use the
PCB placement guideline below to place PCBs in the correct slots. Fill in the PCBs that go into each
slot. Always ensure that the cabinet power factors do not exceed 85. See the notes below and Table 1-
19~Table 1-24.
Notes
●
B101 (BECU)/B102 (BBCU) – Main processor slots. BEXS, BBMS, BSIS are optional subassembly PCBs (see “CTX100
Processor Optional Subassemblies” on Page 1-3).
●
Cabinet slots marked with * provide 8 time slots; all other slots provide 16 time slots.
●
Any combination of up to 96 (basic processor) or 264 (expanded processor) RPTU channels can be installed in the CTX670.
●
RPTU PCBs can only be placed in odd slots of the Base Cabinet and slots S_01, S_03, and S_05 in any Expansion Cabinet.
If 17 or more channels are used, the next highest slot adjacent to the RPTU slot cannot be used. Slots adjacent to 8 or 16
channel RPTU PCBs can be used.
●
BDKU, PDKU, RDSU without Speaker OCA can be in any available slot in any cabinet.
●
BDKU, PDKU, RDSU with Speaker OCA can be in any available slots in the Base and S_01~S_06 in all Exp. Cabs.
●
BDKU/BDKS without Speaker OCA can be in any available slots in the Base and S_01~S_06 in the Expansion Cabs.
Do not install Speaker OCA telephones on BDKU/BDKS.
●
Maximum 80 digital telephones per shelf due to the Power Factor restriction.
●
For more details, see the following Placement Guidelines section.
●
Not all PCB’s are available in the UK (ie RDSU).
