Each 8ATRU PCB connects 8 loop start CO trunks. Each 4ATRU PCB connects 4 loop start CO trunks.
To connect analog trunks (Figure 3-2):

ate 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.
Note: To connect T1 trunks, turn to T1 Trunk PCB on page 2-7.
