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 2-14 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.
4. Terminate the...

CONNECTING TRUNKS
Connecting Analog Trunks (Figure 3-2)
Each 8ATRU PCB connects 8 loop start CO trunks. Each 4
ATRU PCB connects 4 loop start CO trunks.
In Fixed Slot systems, a 4ATRU PCB enables the first
4 trunks (1-4) but disables the second 4 (5-8). With 2
4ATRU PCBs installed, your system has trunks 1-4
and 9-12.
1. Using Figure 2-15 as a guide, insert the mod jacks into the
appropriate connector on the PCB.
2. For each trunk, run one pair cross-connect wire...

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.

Reinstalling the Front Cover (Figure 3-7)

To reinstall the front cover:
1. Hook the tabs on the rear of the cover into their associated slots.
2. Push the front of the cover into place.
3. Screw in the two captive screws that secure the cover to
the cabinet.

EXTERNAL PAGING
Installing External Paging (Figure 4-1)
The CPU provides an External Paging output. You connect the
CPU Paging output to audio inputs on customer provided
Paging systems.
To connect an External Paging amplifier:
1. Find an available connector in a station cable and make sure
it is correctly punched down at the 66M1-50 block.
Follow standard color code order. Be sure the block is
properly cross-connected.
2. For the connector chosen, locate pins 1T and 1R (see Figure
4-1) and connect...
