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).

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.
DN01145897 © Nokia Corporation 23 (128) Issue 2-0 en Nokia Proprietary and Confidential
Page 24

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!

5.8 Connecting power supply

This section specifies the requirements for the mains power supply of the site.
WARNING
MAINS VOLTAGE!
Follow the national legislation when working with the power supply. DNT2Mi must be permanently wired to a disconnect device (for example circuit breaker) in accordance with the current local and national wiring standards.
The following warning applies to the AC power supply:
The protective ground wire can only be used for protective conductor installations. Using the protective ground conductor for other purpose is dangerous to life. Ensure that the ground connection is established before the power outlet is connected to the power interface.
The power supply of DNT2Mi can operate at the following voltages:
90 to 264 V
-20 to -75 V
(AC-powered unit)
AC
(DC-powered unit)
DC
50 to 150 V (remote-powered via ACL2i).
Power interfaces are located on the rear panel of DNT2Mi.
AC mains is recommended to be protected with a lightning and transient overvoltage protector (mainswire-in protector). This protection is not included in DNT2Mi.
Note
In general, mains fuses and supply cables have to be rated according to the national electric safety regulations.
DNT2Mi can be connected either to a positive-grounded or to a negative­grounded DC power system. Principles of the DC powersystems are presented in Figures 20 and 21.

5.8.1 Troubleshooting

Remote-powered DNT2Mi
If there is a backlight but no menu on the display of DNT2Mi, the line is too long, or there is a line break on one of the pairs.
If the initial displays are shown, but the unit resets after a while, the situation may be due to the fact that the line is too long.
If there is no backlight to be seen, the line is too long, or the power supply is broken.
The status LED is red
Check the Status field of the top level menu display and check the Status and Alarm submenus under the Monitoring menu.
Location of error source
Test the connection according to information in Section 7.3.
Installing DNT2Mi
Note
The network terminal must be connected to a ground mains outlet.

5.8.2 Strain relief

In an AC-powered unit, guide the power cable through the strain relief located under the power interface to secure a firm connection (see Figure 24).
In a DC-powered unit, the DC-power cable is connected and guided through the strain relief at the factory.

6 Commissioning DNT2Mi
This chapter describes the most common items that need to be checked before DNT2Mi is taken into use.
DNT2Mi is ready to operate after the power supply (AC, DC, or remote power) and port and line cables are connected. However, identifications and settings should be checked and, if required, statistics and error counter should be reset.
DNT2Mi can be configured, tested, and controlled via:
Front panel LCD and keys

Commissioning DNT2Mi

Service Terminal (using Q1)
Macro Service Terminal Emulator running on a PC (using Q1).
Other Nokia management products, such as Nokia NMS, can be used for the same purpose.
Menu structure for the front panel menus is shown in Chapter 8. Menu structure for Q1 management is shown in Chapter 9.
The tables in Appendix A can be used to mark down information gathered during the commissioning procedure.
Note
It can take up to 60 seconds to save the altered settings. If the power is switched off during this time, the new settings will be lost. During the saving process, you can use the equipment normally.

6.1 Automatic power-up test

When the power is switched on, the unit performs an automatic self test, which is used to check the most vital operational functions of the equipment.
During the power-up test, the Status LED and the Test LED are lit.
DN01145897 © Nokia Corporation 39 (128) Issue 2-0 en Nokia Proprietary and Confidential
Page 40
After the automatic power-up test, the display indicates possible errors found during the test. More detailed information on the fault can then be found in the Self test menu.
The test ends automatically if no fatal errors were found.

6.2 Management

DNT2Mi canbe managed through the lineconnection, local management, or port connection.
The following items need to be checked:
Q1 transmission speed (Q1: 6,1,1)
The Q1 transmission speed needs to be set to match the system management speed.
Q1 address information (Q1: 6,1,2)
The equipment needs a Q1 address to be visible in the NMS systems. You must give a unique address to each equipment.
You can also enter a name for the equipment by using the command 4,7,2,1.
Q1 management path (Q1: 6,1,3)
The routing of the management must be defined to correspond with the system.
Note
The address setting has the following restrictions:
The address 4095 must not be given if the equipment is connected to an NMS bus. This address is a common (broadcast) address.
The address 4094 is reservedfor PC-TMC/STEuse (generaladdress for the PC interface unit).
The address 0 is reserved for PC-TMC/STE use (default address for the PC interface unit).

6.3 Timing source

Before connecting DNT2Mi to a network, you need to know how the network is timed.
DNT2Mi can receive timing information through the line and port interfaces. DNT2Mi can also be used as a network timing source using the unit’s internal timing circuits.
More information can be found in Sections 9.3.3 and 9.3.5.

6.4 Line settings

You have to check the following items:
Line interface (Q1: 6,3,3)
Commissioning DNT2Mi
The line interface settings determine line SHDSL mode, connection speed, and use of wires.
Typically, DNT2Mi is configured as STU-R, Rate Adaptive. The Rate Adaptive mode automatically adapts the requested fixed line rate to STU-C.
Power backoff (Q1: 6,3,6)
Select this option to enable or disable transmit power reduction on short loops.
Line alarms (Q1: 6,3,8 and 6,3,9)
The BER alarm limit and alarm severity have to be checked.

6.5 Port settings

Adapter unit types are automatically recognised by DNT2Mi and can be seen from the Identifications menu, for instance.
DN01145897 © Nokia Corporation 41 (128) Issue 2-0 en Nokia Proprietary and Confidential
Page 42
Port settings (Q1: 6,4, port#,3)
Different adapters include different configurable parameters. Check that port settings are compatible with the equipment they are connected to.
Note
There are some adapter settings that are done by changing the jumper settings on the actual adapter. For more information, refer to document DTE Interface Units for Nokia Data Network Terminals Operating Instructions.
Port alarms (Q1: 6,4, port#,5)
Check that the Q1 alarm visibility is set correctly, that is, enabled or disabled. If Q1 alarms are disabled, port alarms are not visible in the NMS system.
Also, the BER alarm limit and the alarm severity need to be checked.

6.6 Time slot settings (Q1: 6,5)

DNT2Mi canmap a certain amount of time slotsfrom the line connection directly to a port. Check and configure the time slot allocations, if necessary.
Note
Pay close attention to the mapping of time slot 0. For example, time slot 0 cannot be mapped with G.704 adapters.

6.7 Protection settings

Password (Q1: 10,1 and 10,4)
DNT2Mi settings can be protected with a password.
Front panel key rights (Q1: 10,5)
The front panel keys can be used to configure the equipment and to launch tests (Test activation). Both functions can be either enabled or disabled.

6.8 Measurements

After all the settings have been checked, we recommend that you carry out a line quality and a BER test.
Note
Before starting the BER test, reset all statistics and error counters. Read statistics and error counters after the BER test.
Noise margins, Rx and Tx line levels, and attenuations (Q1: 7,1...3)
Establish a link between two units. After the line is up, check the noise margin, Rx level, and line attenuation from the Measurements menu.
You can use Table 28 in Appendix A to mark down the results for line attenuation.
Commissioning DNT2Mi
Bit error rate test
We recommend you to perform a five-minute bit error rate (BER) test. For the test, you need an external test equipment.
You can use Table 27 in Appendix A to mark down the results.
After the tests
Check that all alarms have disappeared and the statistics are still correct.

8.2 Configuring DNT2Mi

When configuring DNT2Mi, take the following into account: at entering a menu level where you can change unit's configuration parameters, a configuration option on the bottom row starts to blink indicating that you are allowed to change it.
Note that the menu has an individual configuration parameter set for each port type.

Nokia Proprietary and Confidential Issue2-0en
Page 61
Using front panel menus
The modem automatically detects the port adapter type in use and shows the corresponding configuration parameters under the Configure: Port menu option.
Note
The text Save? (OK/Exit) appears in the display only when changes have been made to the edit buffer. If the OK key is pressed, the changes are stored and activated. Pressing the EXIT key ends the configuration procedure and nothing is changed.
Note
The asterisk(*) indicates whether a parameter value is currently stored in thenon­volatile memory (that is, the parameter value is used also the next time when the modem is switched on).
Note
If the port adapter is not in place, the menu shows the port parameters that were used previously or, alternatively, the V-type port parameters.

9.2 DNT controls (5)

The DNT controls menu (see Figure 58) contains all possible tests to be activated in DNT2Mi via the Q1 management.
It also shows if DNT2Mi in question is being tested. See the example below.
Display controls:
Port1: -- -­Port2: -- -­Port3: -- -­Line: G.704 --
The DNT Controls menu also has a Self Test submenu, which shows the result of the last self test and enables the activation of a self test. The activation of this test cuts off the connection between the network manager and the unit. The result of the self test can be read after the unit has performed the whole test. The test takes about 20 seconds.

Caution
The activation of a self test also cuts the data connection.

Using Q1 menus

9.3.2 Service options (6,1)

The Service options menu provides also the network manager with three Q1­specific configurable service options, that is, speed used on the management connection, Q1 address, and management path. All these options can be checked and changed.
Q1 speed (6,1,1)
The speed must be selected according to the speed used in the management network.
DN01145897 © Nokia Corporation 97 (128) Issue 2-0 en Nokia Proprietary and Confidential
Page 98
Q1 address (6,1,2)
The Q1 address must be selected before DNT2Mi can be accessed using management.
The address can range from 0000 to 4095. The last address (4095) is a universal address that cannot be selected by the Q1 manager.
Q1 management path (6,1,3)
A Q1 management source is selected from this menu. The source can either be:
Q1 via line, EOC
Local management interface
Q1 via Port1 (only with G.704 adapter).

9.3.3 Timing source (6,2)

This menu allows you to select a source for timing. The timing alternatives are:
Internal
Line
Port1
Transparent.
Figure 73 illustrates the principle of each alternative.
The timing of circuit 103 can be set either by the clock from DTE (113) or by the clock of the equipment (114). See Figures 78 and 79 in Section 9.3.5.
