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 transmission capacity over each 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).

DNT2Mi used in a point-to-point application  
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.

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  
5.1  
Electromagnetic compatibility  
following conditions are fulfilled:  
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 DC-  
powered 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

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  
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!

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 (AC-powered unit)  
AC  
-20 to -75 V (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 (mains wire-in protector). This protection is not included in  
DNT2Mi.

Installing DNT2Mi  
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  
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  
In a DC-powered unit, the DC-power cable is connected and guided through the  
strain relief at the factory.

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  
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  
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.

Data Network Terminal Single-port and Multiport Operating Instructions  
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 can be managed through the line connection, 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 reserved for PC-TMC/STE use (general address for the  
PC interface unit).  
The address 0 is reserved for PC-TMC/STE use (default address for the PC  
interface unit).

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.  
Line settings  
You have to check the following items:  
Line interface (Q1: 6,3,3)  
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.

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 can map a certain amount of time slots from 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.

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.

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.

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 the non-  
volatile 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.

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.

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  
STU-C (6,3,3,1)  
This option defines the unit as a SHDSL Termination Unit (STU) Central  
office. It also sets the bit rate in the line as Fixed. STU-C determines line  
rate to the value given with the menu command Give line rate  
(6,3,3,1,2,1).  
STU-R (6,3,3,2)  
This option defines the unit as a SHDSL Termination Unit (STU) Remote.  
It also sets the bit rate in the line as Rate adaptive. If the line conditions  
(attenuation/noise) allow, STU-R adapts to the line rate set on the STU-C  
side.  
Two-wire (6,3,3,1,2)  
In the 2-wire option, only Line 1 is enabled. Line 2 is idle. See Figure 8 for  
line connector pins.  
Four-wire (6,3,3,1,4)  
In the 4-wire option, both lines (Line 1 and Line 2) are enabled. See Figure  
PSD mask: Symmetric  
Symmetric PSD mask defines the spectral shape of the signal transmitted  
to the line. The symmetric PSD is in use for both 2- and 4-wire modes  
(G.991.2 Annex B).

Give line rate (6,3,3,1,2,n; 6,3,3,1,4,n)  
This setting defines the maximum achievable bit rate in the line only if the  
STU-C option is taken into use.  
In the 4-wire mode, only even numbers for n are allowed (n = 6, 8, 10...32).  
Power backoff (6,3,6)  
ON (6,3,6,1)  
Select this option to enable transmit power reduction on short loops. The  
transmit power is reduced as a function of the line power loss shown in

Line length  
The maximal performance shown in Figure 77 is measured in ideal circumstances  
with the VMOHBU 0.4 mm cable. In a real case, you should reserve 3-6 dB noise  
margin due to changing circumstances in the line.

The maximum connection length of DNT2Mi is defined by the following  
variables:  
Cable attenuation  
The attenuation of a cable depends on thickness and pair capacitance. It  
also depends on impedance mismatching, resulting from connecting  
different types of cables, as well as from the reflections caused by this.  
Cable noise level  
Noise in a cable is mainly caused by cross talk between wire pairs. The  
main sources of noise are units using the same frequency band.

Using Q1 menus  
Cable impulse noise level  
Impulse noise in a cable can be caused, for example, by a telephone's pulse  
dialling signals and exchanges based on relay technique.  
Cable distortion  
DNT2Mi has an effective adapter equalizer, which corrects the distortion  
caused by the cable. However, if the connection is extremely long, the  
extent of the distortion may also restrict the length.  
Remote power feeding  
If a 110 V remote power is used, the maximum line length may be limited.  
If a 145 V supply voltage is used, remote power feeding does not limit the  
maximum cable length. However, the use of a 145 V supply voltage may  
be restricted due to local safety regulations.  
BER alarm limit (6,3,8)

The bit error rate (BER) alarm limit can be either 10 (E-3) or 10 (E-6).

Data Network Terminal Single-port and Multiport Operating Instructions  
This setting can allow the port to react to a RL request (ITU-T V.54) incoming  
from the line or prevent this to happen. If the RL control is allowed, a digital loop  
(loop to line) is established in the port if a request has been detected from the  
incoming data.  
V-type interface settings (6,4, port #,3)  
Synchronous or asynchronous (6,4, port #,3,1)  
The asynchronous or synchronous conversion according to ITU-T V.14. is  
possible using the V.28 adapter in multiport versions in port 2 or 3. The  
conversion is available when bit rates 1200, 2400, 4800, 9600, and 19200  
bit/s are used. No other adapter can be used for this purpose.  
This option allows you to use the asynchronous character length. The bit  
number includes start, data, and stop bits (8 bits: 1 start + 6 data + 1 stop).  
CT103 timing (6,4, port #,3,2)  
The timing of the data coming from DTE can be selected either by circuit  
113 (external, coming from DTE) or circuit 114 (internal generated by the  
This suboption, which does not force DNT2Mi to synchronise to an  
external clock source, allows you to select a clock to be used to get data into  
the DNT port.
