6 Commissioning

This chapter describes the most common items that need to be checked before DNT2Mi-fp is taken into use.

DNT2Mi-fp is ready to operate after the power supply (AC/DC converter, 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-fp can be configured, tested and controlled via:

Commissioning

• Service Terminal (using Q1)

• Macro Service Terminal Emulator or Craft Terminal running on a PC (using Q1)

• Other Nokia management products, such as Nokia NMS, can be used for the same purpose.

Menu structure for Q1 management is shown in chapter Factory Settings.

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.

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 LEDs are lit in the following sequence:

1. All 3 LEDs are lit for 10 seconds.

2. The green power LED is blinking and other are off for 10 seconds during startup and self test.

3. The green power LED is lit and DNT2Mi-fp is ready for use.

DN0445814 © Nokia Corporation 27 (60) Issue 2-0 en Nokia Proprietary and Confidential

If errors were found during the power-up test, more information on this can be found in the Self test menu (Q1: 5,4,0).

6.1 Management

DNT2Mi-fp can be managed through the line connection or local management port LMI.

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 (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.

DNT2Mi-fp Data Network Terminal User manual

You can also enter a name for the equipment by using the command 4,7,2,1

Q1 management via line (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).

6.2 Timing source

Before connecting DNT2Mi to a network, you need to know how the network is timed.

DNT2Mi-fp can receive timing information through the Line or Port interfaces.

28 (60) © Nokia Corporation DN0445814

Nokia Proprietary and Confidential Issue2-0en

DNT2Mi-fp can also be used as a network timing source using the unit's Internal timing circuits.

DNT2Mi-fp can also be used as Transparent timing. This means that both E1 transmission directions are independent.

6.3 Line settings

You have to check the following items:

Line interface (Q1: 6,3,3)

The line interface settings determine line SHDSL mode, connection rate and use of wires.

Typically, DNT2Mi-fp is configured as STU-R, Rate Adaptive. The Rate Adaptive mode automatically adapts the requested fixed line rate to STU-C.
