Make a note of the following…
● When connecting a music source, an External Paging system, or a device controlled by the
CPU relay, make sure the connected device is compatible with the CPU input and output spec-
ifications. Review your system’s Hardware Manual for more.
16DSTU Digital Station PCB (P/N 80021A)
Each 16DSTU PCB connects 16 digital extensions (i.e., keysets). You can also
connect 2-OPX Modules. The 16DSTU has a Mode Switch (for taking the PCB
out of service). It also has a status LED that indicates proper PCB operation — as
well as a port activity LED that flashes faster as traffic on the PCB increases. You
can install up to 2 16DSTU PCBs in a 4-Slot Cabinet. You can install up to 6
16DSTU PCBs in an 8-Slot Cabinet. See DS2000 System Configuration on
page 22 for more.
Make a note of the following…
● When connecting 2-OPX Modules, always observe the System Load Factor.
See page 22 for more.
● You must install a separate power supply for every 2 16DSTU PCBs installed.
● In all systems, you must install a 16DSTU PCB in the first universal slot.
● You can install 16DSTU PCBs in any universal slot.
8ASTU 8 Port Analog Station PCB (P/N 80041B)
The 8ASTU PCB connects 8 analog extensions. These can include single line
telephones, fax machines, modems or Voice Mail ports. Just like the 16DSTU
PCB, the 8ASTU PCB has a Mode Switch (for taking the PCB out of service), a
status LED indicating proper PCB operation, and a port activity LED to indicate
traffic on the PCB. The number of 8ASTU PCBs you can install depends on sys-
tem configuration. Turn to DS2000 System Configuration on page 22 for more.
Make a note of the following…
● The 8ASTU PCB provides high voltage message waiting for single line sets
with high voltage message waiting lamps.
● The 8ASTU PCB also provides Caller ID to single line sets.
● You can install 8ASTU PCBs in any universal slot except the first.
