Preface This manual explains how to install, power up, and configure the 1010PA ISDN Network Termination Unit. Who is this manual for? This manual is for the person installing an ISDN NT1 unit. It contains everything an installer needs to know to power on the unit and confirm that it is functioning correctly. Who to call for assistance If you need assistance with this product, or have questions not answered by this manual, you are welcome to call our Technical Support service.
C H A P T E R 1 Introduction The 1010 is a compact, versatile, and affordable Network Termination 1 (NT1) device. The 1010 is used for connecting Integrated Services Digital Network (ISDN) voice or data Terminal Equipment (TE) to the ISDN line provided by the telephone company. The NT1 is pictured in Figure 1. Three LEDs on the front panel indicate the status of the power, the S/T & U interfaces, and Central Office (CO) loopback testing.
C H A P T E R 2 Setting up your hardware Taking inventory The 1010 package contains the following items: ■ One 1010 unit ■ One RJ11 to RJ45 cable ■ One RJ45 to RJ45 cable ■ One power supply unit (AD62010) ■ One plastic wall mount bracket ■ Two jumpers ■ Two screws and two plastic anchors for wall mounting ■ User’s Guide ■ One warranty card Front panel LEDs There are three (3) LEDs on the front panel of the 1010.
S/T&U LED The S/T&U LED will flash for a few seconds when the 1010 is first powered on. This LED will then go off, provided that the S/T & U interfaces are working properly. a If there is no ISDN line connected to the U-interface or the line is not activated, then the S/T&U LED will be on continuously. b If the U-interface is detected, but is not in sync., the S/T&U LED will flash eight times per second. In this case, the S/T device will not work until sync. is restored on the U-interface.
C H A P T E R 3 Installing your unit Rear panel 1 The 1010 rear panel (see Figure 3) has three RJ45 connectors, two for the S/T-interface and one for the U-interface. 2 The two RJ45 connectors for the S/T interface, located on the left side of the rear panel, are connected in parallel internally. When one RJ45 connector is being used, the maximum range is 3,300 feet (1,000 meters). When both RJ45 connectors are being used, the total range on both shall not exceed 660 feet (200 meters).
Table 2—U interface pin assignments Pin Function Pin Function 1 — 2 — 3 — 4 TIP 5 RING 6 — 7 — 8 — Power connector The 4-pin mini DIN power connector is located on the side of the 1010. This design will prevent the weight of the 1010 power adapter from accidentally pulling off, when the 1010 is wall mounted. The power connector pin assignments are shown in Table 3.
Internal jumper settings The 1010 is shipped with 100Ω Termination Resistance (TR). This TR is added to the S/T bus when dip switches 1 & 2 are set to the on position. If the installed S/T bus ISDN CPE provides 100Ω TR, dip switches 1 & 2 should be set to the off position to provide 0Ω. When the ISDN CPE provides 50Ω, the 1010 needs to be adjusted to provide the other 50Ω, instead of its default of 100Ω. Changing the 1010 TR is done through an internal jumper.
Wiring instructions Figure 4 shows the wiring diagram of the 1010 with the ISDN Customer Premise Equipment (CPE) and the Line Termination (LT). Follow the instructions given below to set up the 1010: Figure 4—Wiring diagram 10 1 Adjust the DIP switches for the desired S/T wiring setup (see Table 4). 2 Connect the DC power plug of the AD62010 to the power connector on the side of the 1010. 3 Plug the AD62010 into the AC power outlet.
Wall mounting instructions To mount the 1010 on a wall, follow these instructions. 1 Drill two holes in the wall corresponding to the holes on the wall mount bracket provided with the 1010. 2 Insert the plastic wall anchors into the wall holes, using a hammer if necessary. 3 Align the bracket with the anchors, and use the screws provided to mount the bracket on the wall. 4 Align the holes on the back of the 1010, with the hooks on the wall mount bracket.
C H A P T E 4 R S/T bus configuration The 1010’s dip switch settings relate to the five possible configurations of the S/T bus. The 1010 allows the user to adjust the S/T bus Termination Resistance (TR) and S/T bus timing. Figure 6—End of Passive Bus (P-P) DIP SWITCHES O1 N 2 3 TE. 1010 4 TR 3300 ft.
