This manual introduces the DNT2Mi-fp network terminal and provides information needed for its installation and use. This manual is intended for those who use DNT2Mi-fp as a network terminal. If you use it in a ACL2i-DNT2Mi-fp connection, refer to the ACL2i User Manual, which contains descriptions of the ACL2i, its functions and Q1 menus.
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...
6-pin modular jack, RJ-11 Figure 6. Power supply DNT2Mi-fp can be fed with either, 48VDC or remotely via ACL2i through the line. It is also possible to use a AC to DC converter (110/230VAC to 48VDC) to feed power to the DNT2Mi-fp.
DNT2Mi-fp Use of signal 108 when using MSTE If signal 108 is on it will disconnect the DNT2Mi-fp from the management network and no other network elements can be managed through the DNT2Mi-fp. If signal 108 is off then it is possible to manage the network elements through the DNT2Mi-fp.
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.
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). Management DNT2Mi-fp can be managed through the line connection or local management port LMI. The following items need to be checked:...
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. Line settings You have to check the following items:...
Basic frame of CRC multiframe (Q1: 6,4,1,2 or 6,4,1,3) Alternative if fractinal 2M is needed. In this case payload rate is n 31) and one time slot is reserved for framing. Frame is terminated at DNT2Mi-fp port interface. Port statistics is available.
Default password for DNT2Mi-fp protection is DNT2Mi, and it can change by menu option (Q1: 10,4,3). 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.
