CHAPTER
1Introduction
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.
This installation guide describes how to install the 1010 for use with ISDN TE(s).
The 1010 may be mounted on a wall or simply placed on a desktop.

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.

When the 1010 is plugged into the wall outlet, the POWER LED will be on.

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 prop-
erly.
aIf there is no ISDN line connected to the U-interface or the line is not acti-
vated, then the S/T&U LED will be on continuously.
bIf 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.
cIf the U-interface is in sync., but the S/T-interface is not, then the S/T&U
LED will flash once per second. There must be an S/T device connected to
the S/T-interface before this light will go off.
dOnce both the S/T- and U-interfaces are in sync., the S/T&U LED will go
off.
Loopback LED
The U LOOP BACK LED will light only during a telephone company full "2B+D"
loopback test. The ISDN line will not be available until this testing is completed.

Rear panel
1The 1010 rear panel (see Figure 3) has three RJ45 connectors, two for the
S/T-interface and one for the U-interface.
2The 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 connec-
tor 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). The RJ45 pin connector assignments for the
S/T interface are shown in Table 1.

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.
Table 3—Power connector pin assignments
DIP switch setting
A block of four DIP switches is located on the bottom of the 1010. Use the DIP
switches to configure the 1010 according to the settings shown in Table 4. For S/T
wiring configuration, please refer to Chapter 4.

Internal jumper settings
The 1010 is shipped with 100ΩTermination 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 100ΩTR, dip switches 1 & 2 should be set to the off posi-
tion 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. Following is the procedure to change the
internal jumper.
WARNING!
Always disconnect all telephone lines at the network interface,
and power connections from the wall outlets before servicing
or disassembling this equipment.
1To open the 1010, remove the four corner screws from the bottom of the
1010.
2On the component side of the printed circuit board, locate JP3 & JP4 (in
the middle of the board). Table 5 shows the setting of the dip switch 1 & 2
for different Termination Resistance settings.

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
1Adjust the DIP switches for the desired S/T wiring setup (see Table 4).
2Connect the DC power plug of the AD62010 to the power connector on the
side of the 1010.
3Plug the AD62010 into the AC power outlet. The POWER LED will light
and the S/T&U LED will light or flash depending on the line status.
4Connect one end of the RJ45 cable into the U-interface connector on the
1010. The other end goes into the U-interface wall outlet.
5Switch on the power to the ISDN terminal equipment. Connect one end of
the RJ45 cable provided, to one of the S/T connectors on the 1010, and
connect the other end to the ISDN TE.
6If a second ISDN TE will be used, repeat step 5 to connect the second ter-
minal to the second S/T connector.
7The S/T&U LED may begin to flash for a few seconds. The LED will go
off when the communication paths have linked. When the LED goes off,
the ISDN CPE is ready for communication.

Wall mounting instructions
To mount the 1010 on a wall, follow these instructions.
1Drill two holes in the wall corresponding to the holes on the wall mount
bracket provided with the 1010.
2Insert the plastic wall anchors into the wall holes, using a hammer if neces-
sary.
3Align the bracket with the anchors, and use the screws provided to mount
the bracket on the wall.
4Align the holes on the back of the 1010, with the hooks on the wall mount
bracket.
5Press the 1010 gently but firmly onto the mounting bracket. Then slide the
1010 down gently until it hooks onto the bracket and locks into position.

Power source
Use the 1010 only with power adapter model AD62010. The power adapter sup-
plies power to the NT1 only.
