DS2000 Configuration Guidelines
4 Slot Cabinets
• Do not install more than 2 16DSTU PCBs under any circumstances.
• The first 16DSTU PCB you install must be in the first slot (CN1).
• You can install up to 40 extensions maximum, as follows:
(2) 16DSTU PCBs = 32 digital extensions
(1) 8ASTU PCB = 8 analog extensions
Total = 40 extensions
• You can install up to 24 trunks maximum, as follows:
(3) 8ASTU PCBs = 24 analog trunks
• Maximum configuration is 48 ports.
• The total of all extensions and trunks cannot exceed 48.
• Always use the System Load Factor table to check your system configura-
tion.
8 Slot Cabinets
• Do not install more than 2 16DSTU PCBs for each power supply.
• The first 16DSTU PCB you install must be in the first slot (CN1).
• You can install up to 96 extensions maximum.
• You can install up to 48 trunks maximum.
• The total of all extensions and trunks installed cannot exceed 104.
• Maximum configuration is 104 ports.
• 8 slot cabinets require A series PCBs, as follows:
