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.

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.
