Strata CTX100 Cabinet Slot Configuration
Considerations
Write in the PCBs installed in each cabinet slot in the Cabinet Diagram below. Use the PCB placement
guideline below to place PCBs in the correct slots. A number of tables provide CTX100 capacities and
configuration examples in this section.

For cost-effective configurations, try to fit all PCBs into the CTX100 Base Cabinet. This allows up to
16 loop start Exchange lines and 32 DKTs, and up to 30 PRI Exchanges by 40 DKTs.
If 9~16 DKTs require Speaker OCA, place BDKU/BDKS PCBs in S103 if it is available.
Consult the following tables of maximum system capacity slot configurations as guidelines for
PCB slot placement.
Check system capacities in
limitations.
Notes
1. Always check the cabinet power factors see
Page 1-27 to make sure the installed PCBs and telephones do not exceed the power factor
limitations.
2. ACTU processor optional subassembly functions (see
Subassemblies" on Page
the exception of RPTU PCBs which should be installed in S103 and BDKU/BDKS PCBs that
support Speaker OCA.
3. RPTU PCBs can be placed in any odd numbered slot using the following rules:
If RPTU is placed in Slot 103 (preferred) with 30 channels, another PCB can still be installed
in S104.
If RPTU is placed in Slots 101, 105, or 107 another PCB can not be installed in the next slot.
4. Digital telephone PCBs that support Speaker OCA can be placed in slots using the following rules:
If ADKU, BDKU (without BDKS) or PDKU must support Speaker OCA, it can be installed in
any slot; another PCB can be installed in the next even slot.
If a BDKU/BDKS PCB must support Speaker OCA it can only be installed in Slot 103;
another PCB can be installed in S104.
