INSTALLING PCBS 2-10 Analog Station (8ASTU and 4ASTU) PCBs (Figures 2-8 and 2-9) The 8ASTU PCB provides connection for 8 analog extensions. The 4ASTU PCB connects 4 analog extensions. Refer to Section 3, Installing Extensions and Trunksfor wiring instructions.To install the ASTU PCB: 1. Plug in ASTU PCBs as required. In U Slot systems, see System Configuration in Section 1. In Fixed Slot systems, you can only plug an ASTU PCB into slot CN2. An 8ASTU PCB provides analog extensions 316-323. A 4ASTU PCB provides analog extensions 316-319. 2. Set the mode switch on the ASTU to RUN. Figure 2-8 ANALOG STATION (ASTU) PCBFigure 2-9 INSTALLING THE ASTU PCB 80000 - 31A Mode Switch 4 Slot Cabinet Shown
2. PCB Installation 2-11 INSTALLING PCBs Analog Trunk (8ATRU and 4ATRU) PCBs (Figures 2-10 and 2-11) The 8ATRU provides connection for 8 loop start analog trunks. The 4ATRU PCB connects 4 loop start analog trunks. Refer to Section 3, Installing Extensions and Trunksfor wiring instructions.To install ATRU PCBs: 1. Install ATRU PCBs as required. In U Slot systems, see System Configuration in Section 1. In Fixed Slot systems, plug the 8ATRU PCB for trunks 1-8 into slot CN3. Plug the 8ATRU PCB for trunks 9-16 into slot CN4. 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, you system has trunks 1-4 and 9-12. 3. Set the mode switch on each installed 8ATRU to RUN. Figure 2-10 ANALOG TRUNK (ATRU) PCBFigure 2-11 INSTALLING THE 8ATRU PCB 80000 - 32 Mode Switch 4 Slot Cabinet Shown
INSTALLING PCBs 2-12 8 Circuit Caller ID Daughter Board (Figure 2-12) For Caller ID capability, install 8 circuit Caller ID PCB daugh- ter boards (P/N 80013) on the 8ATRU PCBs (P/N 80011A ). The Caller ID PCB provides Caller ID capability for all eight trunk circuits on the 8ATRU PCB. Every 8ATRU PCB in the system can have a Caller ID daughter board. If you are installing Caller ID on an 8ATRU PCB in the last slot, you may have to adjust your system’s ground wire connection so it won’t obstruct the daughter board. To install ATRU PCBs: 1. Remove the metal bracket that holds the PCBs in place. 2. Remove the 8ATRU PCB. 3. Remove the headers from 8ATRU PCB connectors CN3 and CN4 and store in a safe place (see Figure 2-12). 4. Align the Caller ID PCB standoffs over the holes located in the 8ATRU PCB. Note that the CN2 connector on the Caller ID PCB should be above the CN3 connector on the 8ATRU PCB. CN3 on the Caller ID PCB should be above CN4 on the 8ATRU PCB. CN1 on the Caller ID PCB should be above CN2.5. Push the PCB down until the standoffs snap into place. 6. Plug the 8ATRU PCB back into the system cabinet. 7. Refer to your system’s Software Manualfor additional fea- ture information and any required system programming.

INSTALLING PCBs 2-14 4 Circuit Caller ID Daughter Board (Figure 2-13) For Caller ID capability, install 4 circuit Caller ID PCB daugh- ter boards (P/N 92012) on the 4ATRU PCBs (P/N 80010A ). The Caller ID PCB provides Caller ID capability for all four trunk circuits on the 4ATRU PCB. Every 4ATRU PCB in the system can have a Caller ID daughter board. If you are installing Caller ID on a 4ATRU PCB in the last slot, you may have to adjust your system’s ground wire connection so it won’t obstruct the daughter board. To install ATRU PCBs: If you install a P/N 92012 Caller ID PCB on an 8ATRU PCB P/N 80011A, you will get Caller ID ser- vice only on the first four PCB trunk circuits. 1. Remove the metal bracket that holds the PCBs in place. 2. Remove the 4ATRU PCB. 3. Remove the headers from 4ATRU PCB connector CN3 and store in a safe place (see Figure 2-13). 4. Align the Caller ID PCB standoffs over the holes located in the 4ATRU PCB.Note that the CN2 connector on the Caller ID PCB should be above the CN3 connector on the 4ATRU PCB. CN1 on the Caller ID PCB should be above CN2. 5. Push the PCB down until the standoffs snap into place. 6. Plug the 4ATRU PCB back into the system cabinet. 7. Refer to your system’s Software Manualfor additional fea- ture information and any required system programming.

2-16 CONNECTING BLOCKS Working With 8-Pin Jacks The system uses 8-pin mod jacks to connect extensions, trunks and optional equipment. Using the Installation Cable (P/N 80892) makes it easy to connect the PCBs to standard 66M1-50 connecting blocks. These cables have 6 8-pin modular jacks on one end and are unterminated on the other. In general, each cab- inet needs: One 66M1-50 block and Installation Cable (P/N 80892) for extensions and optional equipment. One 66M1-50 block and Installation Cable (P/N 80892) for trunks. Note:Depending on your PCB configuration and local codes, you may need an additional 66M1-50 block and Installation Cable (P/N 80892) for optional equipment. Punching Down the Cables (Figures 2-14 to 2-18) The Installation Cables have 6 8-pin jacks installed on one end and are unterminated on the other. Each 8-pin jack connects 4 extensions or 4 trunks. 1. For each 66M1-50 block, punch down the Installation Cable in standard color-code order. Use Figure 2-14 when connecting extensions.Use Figure 2-15 when connecting trunks. 2. After you have punched down your cables, route them through the side of the cabinet and secure them with the strain relief (Figure 2-16). 3. If you are using non-A PCBs (e.g., 16DSTU PCB P/N 80021) in a 4 Slot Cabinet, be sure to install RFI Suppressor Assemblies on each station and trunk cable. Follow Figure 2- 17 and snap an assembly around each 50-pin cable.You cannot use non-A PCBs in an 8 Slot Cabinet. Making your own Cables (Figure 2-18) If you want to make your own cables (instead of using Installation Cable P/N 80892), follow the pinouts in Figure 2-18.
