Introduction to DNT2Mi-fp 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).

Front view of DNT2Mi-fp 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.
DNT2Mi-fp Data Network Terminal User manual • 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).

Commissioning 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 Data Network Terminal User manual 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.
Commissioning 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.
DNT2Mi-fp Data Network Terminal User manual Line alarms (Q1: 6,3,8 and 6,3,9) The BER alarm limit and alarm severity have to be checked. 6.4 Port settings You have to check the following items: Port framing (Q1: 6,4,1) Check that the 2M data interface settings are compatible with the equipment they are connected to. No frame (Q1: 6,4,1,1) Alternative if full 2M is needed and no framing is required. Port statistics is not available. Only UAT is calculated if there is no G.703 signal present at the port.
Commissioning Default password for DNT2Mi-fp protection is DNT2Mi, and it can change by menu option (Q1: 10,4,3). 6.6 Measurements After all the settings have been checked, it is recommended that you carry out a line quality and 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...4) Establish a link between two units.
