!! Install RFI Suppressor Assemblies as shown below !!
You must install separate RFI Suppressor Assemblies for the
ground wire, the CPU connections (i.e., mod jack and RS-232
cables), each trunk cable and each station cable. The suppres-
sors mustbe mounted inside the cabinet and as close to the
appropriate PCB as possible.

CONNECTING EXTENSIONS
Connecting Extensions (Figure 3-1)
Each 16DSTU PCB connects 16 digital extensions. Each
8ASTU PCB connects 8 analog extensions. Each 4ASTU PCB
connects 4 analog extensions.
1. Using Figure 2-11 as a guide, insert the mod jacks into the
appropriate connector on the PCB.
2. Install a modular jack for each extension within 6 feet of the
telephone’s location.
3. For each extension, run one-pair 24 AWG station cable from
the cross-connect block to the modular jack.

Connecting Analog Trunks (Figure 3-2)
Each 8ATRU PCB connects 8 loop start CO trunks.
1. Using Figure 2-12 as a guide, insert the mod jacks into the
appropriate connector on the PCB.
2. For each trunk, run one pair cross-connect wire between the
pins on the cross-connect block and the CPE (customer side)
of the telco’s RJ21X.
3. Install bridging clips as required.

POWER UP AND SYSTEM LEDS
Power-Up (Figures 3-3 to 3-5)
Now that all the PCBs you need are installed and you have
cabled the system, you can now power-up. You do not need to
reattach the right side panel before powering up the system.
Leaving the right side panel removed makes the station and
trunk cabling more accessible.To power up the system:
1. Make sure the system is properly grounded and the PCB
bracket is reinstalled and secured.
2. Install surge protectors in the AC outlet you intend to use...

FINISHING THE INSTALLATION
Reinstalling the Side Panel (Figure 3-6)
To reinstall the side panel:
1. Carefully realign the right side panel and slide it into position.
2. Reattach the two screws that secure the right side panel to
the cabinet.
