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

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!

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 (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.
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 negative-
grounded DC power system. Principles of the DC power systems are presented in

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.

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.
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.

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.

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.

Figure 77. Maximal cable length
Factors limiting connection length
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.

•
•
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.
