Step 2: Connect the DC power plug of the power supply to the power connector on the rear of the UT3620 as shown in Figure 4. Place the power cable into the wire clip to secure it. Figure 4. Power Connector Plug the power supply into an AC power outlet. - Page 11 This is illustrated in Figure 6 on the next page. The Line Status LED will illuminate solid green indicating that the TE has synchronized with the ISDN line. Repeat this step for the remaining S/T-Interfaces. UT3620 Triple NT1 Installation Guide...

If the LED continues to blink slowly, the TE has not synchronized. Note: Video Conferencing products often require the software to be operating to achieve synchronization. Check the RJ-45 to RJ-45 cable connections, and verify both RJ-45 ports for the S/T-Interface. Also, verify the S/T Bus Configuration is correct for the installation. -

Page 14: Appendix B: S/T Bus Configuration
Appendix B: S/T Bus Configuration Combinations of these settings and the wiring requirements of the installation determine the configuration for each line. Each S/T-Interface is configured separately to provide flexibility. Default Configuration: The manufacturer’s default DIP Switch configuration will work on almost all installations. No more than four terminals can be attached and each terminal must be the same distance away from the NT1, within 10 meters tolerance, to a... -

TR (or have a TR wired into the line just before the terminal). Up to eight terminals can be supported in this configuration. From NT1 to last TE is 200m TE with TR Figure 9. Short Bus Configuration UT3620 Triple NT1 Installation Guide... -
Page 16: Figure 10: Extended Bus Configuration
Extended Bus Configuration: This covers cases where more than 200 meters is required between the NT1 and the TE. Solution: Wire a TR a fixed distance from the NT1, or if only one terminal is needed, turn on a built-in TR. If a TR is wired into the line, up to four terminals can be supported as long as each is within 25 meters from the TR. -

25 meters of a TR. No TE symmetry is required, so one TR can have four terminals connected while the second only has one. From NT1 to TR is 140m Figure 11. Y-Bus Configuration UT3620 Triple NT1 Installation Guide... -
Page 18: Appendix C: Interface Pin Assignments
Appendix C: Interface Pin Assignments Each interface has specific pinouts which are important for electricians and technicians to know. Anyone installing wiring for the UT3620 should pay close attention to this information. All interfaces described here are located on the rear panel of the UT3620. -
