Configuration
with the exception of RDTU and RPTU PCBs that support more than 16 channels, and BDKU/
BDKS PCBs that support Speaker OCA.
3. RDTU and RPTU PCBs can be placed in any odd numbered slot using the following rules:
• If RDTU or RPTU is placed in Slot 103 (preferred) with 8, 16 or 24 channels, another PCB
can still be installed in S104.
• If RDTU or RPTU is placed in Slots 101, 105, or 107 with 8 or 16 channels, another PCB
can still be installed in the next slot; however, if 17~24 channels are required the next even
slot must be vacant.
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.
