2 Introduction to DNT2Mi-fp

Nokia DNT2Mi-fp is a fixed port 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 symmetrical 2M data interface (ITU-T G.704).

The DNT2Mi-fp Data Network Terminal can be used for example for BTS and PABX (E1) connections (see Figure 2). DNT2Mi-fp can be controlled, configured, and tested using Nokia’s common network management system (NMS). It can also be controlled locally using MSTE or Craft Terminal running on a PC or ST (hand held service terminal).

When power is switched on, the unit performs an automatic self test, which is used to check the most vital operational functions of the equipment. After the test, the device is ready for use.

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 others are off for 10 seconds during startup and self test.

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

The green DSL LED indicates state of the line.

• If there is no line signal, the DSL LED is off.

• If line is handshaking, the DSL LED is blinking.

• If the line is up and running, the DSL LED is lit.

The yellow Alarm LED indicates alarm situation.

• If there is no alarm situation, the LED is off.

• The Alarm LED is lit for instance if:

• no line signal or handshaking is ongoing or too high bit error ration (BER).

• no E1 data signal or framing error or too high bit error ration (BER).

For more information see the Maintenance chapter.
