2 Introduction to DNT2Mi

Introduction to DNT2Mi

Figure 1. Single-port (above) and multiport (below) DNT2Mi terminals

Nokia DNT2Mi is a single- or multiport (sp/mp) data access network terminal intended for customer premises. It provides a two-wire or four-wire SHDSL line interface (ITU-T G.991.2) and up to three interchangeable DTE interface units. The following interface units are available (for more information, refer to Table

2):

• V.11

• V.28

• V.35

• X.21

• G.703/64k

• G.703/2M

DN01145897 © Nokia Corporation 11 (128) Issue 2-0 en Nokia Proprietary and Confidential

Data Network Terminal Single-port and Multiport Operating Instructions

• G.704/2M

• EIA-530-A

• Ethernet

•VF

• D2048

Single-port and multiport versions

The single-port version offers one of the DTE interface types mentioned above, whereas the multiport version can house up to three independent DTE interface types. Additionally, the multiport version includes Time Division Multiplexing (TDM), which allows dividing the transmissioncapacity overeach DTE interface according to application needs.

Power supply

DNT2Mi can be fed either with AC 90 to 264 V, DC -20 to -75 V, or remotely via ACL2i through the line.

Management

DNT2Mi can be managed locally with the front panel keys, Nokia’s hand-held Service Terminal, or with a Microsoft Windows-based Macro Service Terminal Emulator (MSTE) program running on a PC. For more information about supported Windows operating systems, refer to the Macro Service Terminal Emulator User's Manual.

DNT2Mi can also be managed remotely with Nokia's Network Management System (NMS).

Nokia Proprietary and Confidential Issue2-0en

3 Applications

The DNT2Mi Data Network Terminal can be used for Local Area Network (LAN) and Private Automatic Branch Exchange (PABX) connections (see Figure

2). The device can be controlled, configured, and tested either by using the front panel keys and the LCD display or via Nokia’s common network management system.

DNT2Mi provides an n x 64 kbit/s (n = 1 to 32) data access and enables TDM multiplexing of line rates to three n x 64k ports. It also incorporates V.110 rate adaptation enabling port rates lower than 64 kbit/s.

The line rate is n x 64 kbit/s (n = 3 to 32 in two-wire connection; n = 6 to 32 in four-wire connection but only even numbers can be used), and the Trellis Coded Pulse Amplitude Modulation (TC-PAM) coding is used for transmission.

5 Installing DNT2Mi

This chapter provides instructions on how to mechanically install and connect DNT2Mi. The menu settings required for bringing the unit into use can be found in Chapter 6.

5.1 Electromagnetic compatibility

DNT2Mi complies with EMC specifications (refer to Chapter 10) when the following conditions are fulfilled:

Installing DNT2Mi

• The securing screws of the multiport DNT2Mi cover are properly fastened.

• All multiport DNT2Mi ports are provided with adapters, or unused ports provided with dummy plates.

• The DTE cables and connectors are provided with reliable shielding.

• The connector’s connecting screws are properly fastened, so that shielding integrity from the metal housing of the equipment to the cable shield over the interconnecting interface is secured.

• A grounded 3-conductor mains cord and a grounded mains outlet for mains-powered DNT2Mi terminals, or a similar grounding for DCpowered versions, is used.

5.2 Grounding of DNT2Mi

The AC-powered version of DNT2Mi is grounded properly when the mains cord is connected to a grounded mains outlet.

The DC-powered version of DNT2Mi has a separate pin reserved for the ground connection, refer to Section 5.8.

Data Network Terminal Single-port and Multiport Operating Instructions

5.3 Clearances around DNT2Mi

When installing DNT2Mi on a wall or freely on a horizontal level, you must ensure that there is an adequate space for connecting cables. Recommended clearances are shown in Figure 11.

In a modem-shelf installation, slot sizing of the shelf ensures adequate horizontal clearances between the units.

Heat released from the unit is insignificant, and does not therefore set requirements on the clearances around the equipment. DNT2Mi is cooled through natural convection through air inlets and outlets located in the bottom and top of it.

Caution

Do not cover DNT2Mi. The air inlets and outlets must be unobstructed to maintain proper circulation of air.

Do not cover!

Approx. 100 mm

Approx. 440 mm

Figure 11. Clearances around DNT2Mi

Approx. 100 mm

Nokia Proprietary and Confidential Issue2-0en

5.4 Work order

First examine the unit and make sure that it has not been damaged during transportation. Also, check that you have the cables needed for connections (mains cable, DTE cable, line cable).

Then proceed according to the steps below:

1. Insert DTE interface units into the DNT2Mi terminal, if needed, refer to Section 5.5.

2. Insert DNT2Mi in a special shelf-like modem subrack or on a wall, if needed, refer to Section 5.7. Otherwise, proceed with the free-standing installation described in Section 5.6.

3. Plug the mains cord into a grounded mains outlet (AC version) or connect the DC power lines (refer to Section 5.8).

Installing DNT2Mi

4. Connect DNT2Mi to your DTE and to the line.

5. Switch on the power (AC or DC). The modem performs a self test.

6. Adjust the LCD contrast, if needed, refer to Section 5.9.2.

Then proceed to check that the main settings are correct (the settings are described in Chapter 6). The settings can be checked and altered using either the front panel keys and display (Chapter 8) or by using the Q1 connection (Chapter 9).

5.5 Inserting DTE interface units

Caution

The equipment is sensitive to static electricity. When handling the units you should follow the general instructions concerning handling of ESD-sensitive equipment. You should always take antistatic precautions (such as a wrist grounding) when handling a plug-in unit once it has been removed from its antistatic packaging.

If the DTE interface units are not pre-inserted or a unit needs to be changed, follow the instructions below.

Data Network Terminal Single-port and Multiport Operating Instructions

To insert DTE interface units:

1. Make sure that the power is switched off.

Caution

The multiportversion of DNT2Mi has threeslots and the DTE interface units that go to the upper slots (2 and 3) need to be inserted upside down.

2. Insert a DTE interface unit carefully into the slot.

3. Tighten the two screws.

Screws

Nokia Proprietary and Confidential Issue2-0en

5.6 Free-standing installation

Note

A free-standing installation of DNT2Mi is allowed only if permitted by the local electric safety regulations!

To install DNT2Mi free-standing:

1. Place DNT2Mi on a dry and clean horizontal level.

Caution

Make sure that the unit may not be dropped incidentally!

Installing DNT2Mi

2. Guide the strain relief as advised in Figure 24.

3. Take care of the grounding as advised in Section 5.2.

5.7 Installing DNT2Mi on a wall or into a rack

This section gives instructions for the mechanical installation of DNT2Mi into a 19-inch rack or on a wall.

The mounting accessories used are:

• DS 62000.1 Modem shelf for low housing (single-port, 7 units)

• DF 62001.1 Wall-mounting bracket

• DF 62010.1 DC-power rail.

5.7.1 Installing DNT2Mi on a wall

Note

When selecting an installation location, make sure that all cables can be easily connected. See Figure 11 for adequate clearances.

Installing DNT2Mi

2. Fasten the mounting bar into the opening in the bottom of DNT2Mi with the screw included. Use a Phillips screwdriver.

3. Mark fixing points on the wall for two screws using the wall-mounting bracket as schema (Figure 14).

- Position the bracket on the wall in horizontal position, its hooks

facing upwards. Use a spirit level to check that the bracket is in a straight position.
