NT1 ACE3 User Manual Unit Overview The ADTRAN NT1 ACE3 provides up to three basic rate interfaces between customer ISDN terminal equipment (S/T) and the ISDN network (U). Figure 1-1 is an illustration of the NT1 ACE3. 3 2 1 READY ERROR READY ERROR READY ERROR NT1 ACE3 Figure 1-1 ADTRAN NT1 ACE3 12VDC 3 POWER S/T 2 U S/T 1 U S/T U Figure 1-2 Interface Connectors The three RJ-45 connectors labeled U connect to the ISDN network.
NT1 ACE3 User Manual The U-interface complies with ANSI T1.601 and ITUTI.430 recommendation Standard. The S/T-interface complies with ANSI T1.605 and ETSI ETS 300012 Standard. The ADTRAN NT1 ACE3 is a stand-alone unit. An external power source is provided for the NT1 ACE3. External power is supplied by the ADTRAN Power Supply, part number 336012VUR01. LED Indicators Table 1-A describes the status of the LEDs located on the front panel of the NT1 ACE3.
NT1 ACE3 User Manual network problem. A slower 1 Hz rate (1 flash per second) indicates an S/T interface problem. If an ERROR indicator is not illuminated and the READY indicator is flashing, then a network test is in progress. Network command tests cause a faster 8 Hz flash rate. Inspection After unpacking the unit, immediately inspect it for possible shipping damage. If damage is discovered, file a claim immediately with the carrier; then contact ADTRAN Customer Service.
NT1 ACE3 User Manual Maintenance The ADTRAN NT1 ACE3 requires no routine maintenance to operate. In case of equipment malfunction, refer to the sections Remote Testing on page 4 and Repair and Return on page 4 or remove the unit and replace it with another unit optioned in an identical manner. Remote Testing Network test features include a loopback test initiated at the central office. This test confirms network integrity to the NT1 ACE3. Repair and Return Repairs should not be performed in the field.
NT1 ACE3 User Manual Connections The NT1 ACE3 is optioned for standard 100Ω termination. Tables 1-B and 1-C give the connector pin assignments, and Figures 1-3 and 1-4 show the connectors.

NT1 ACE3 User Manual Powering with the NT1 ACE3 Power Supply The ADTRAN NT1 ACE3 Power Supply, part number 336012VUR01, provides power to the NT1 ACE3. To connect the NT1 ACE3 to the external power supply, perform the following steps as illustrated in Figure 1-5. 1. Connect the Power Supply to the NT1 ACE3 at the POWER jack located on the NT1 ACE3 rear panel. 2. Plug the Power Supply into the nearest wall outlet supplying 120 VAC, 60 HZ. 3. On the NT1 ACE3, verify that the ERROR indicators are illuminated.
NT1 ACE3 User Manual Connecting the Terminal Equipment After successfully powering up the NT1 ACE3, the ERROR indicators should be on and the READY indicators should be flashing. Make sure that terminal equipment (TE) is properly terminated. Plug each TE into one of the S/T connectors at the rear of the unit. The ERROR indicators should extinguish a few seconds after power is applied to the TE. If the ERROR indicators fail to go out, see the section Troubleshooting on page 10.
NT1 ACE3 User Manual Typical Configuration This configuration allows you to connect up to three TEs at ranges up to 3000 feet from the NT1 ACE3, as shown in Figure 1-6. A termination resistor should be centrally located to the TEs. The NT1 ACE3 TERMINATION is set to 100 Ω. The TEs should be set to 100 Ω.
NT1 ACE3 User Manual Troubleshooting If your NT1 ACE3 does not operate properly, please check the list of symptoms and solutions below. For further assistance, please contact ADTRAN Technical Support at 888 4ADTRAN. ERROR and READY indicators not illuminated. • Check the power source to the NT1 ACE3 for sufficient power. • The NT1 ACE3 power supply may be defective: Call ADTRAN Technical Support. • The NT1 ACE3 may be defective: Call ADTRAN Technical Support.
NT1 ACE3 User Manual ERROR indicators illuminated, READY indicators flash at a slower 1Hz rate. Local bus failure: • TE not connected: Connect TE. • TE not receiving power from NT1: Consult TE documentation. • TE not terminated properly: Correct termination. • TE ISDN parameters not configured properly: Reconfigure TE (SPIDs, LDNs, switch type, etc.). READY indicators do not illuminate. • Problem with ISDN network: Contact telephone company. • ISDN line not plugged into U jack: Plug ISDN line into U jack.
