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:
CPU PCB P/N 80025A
Power Supply P/N 80005A
16 DSTU Digital Station PCB P/N 80021A
8ASTU 8 Port Analog Station PCB P/N 80041A
