  • Page 11: Introduction To Dnt2Mi

    Introduction to DNT2Mi Figure 1. Nokia DNT2Mi is a single- or multiport (sp/mp) 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 up to three interchangeable DTE interface units.
  • Page 12 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.

  • Page 13: Applications

    The DNT2Mi Data Network Terminal can be used for Local Area Network (LAN) and Private Automatic Branch Exchange (PABX) connections (see Figure 2). The device can be controlled, configured, and tested either by using the front panel keys and the LCD display or via Nokia’s common network management system. PABX Figure 2.
  • Page 14 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. 14 (128) © Nokia Corporation DN01145897 Nokia Proprietary and Confidential Issue 2-0 en...

  • Page 15: Construction And Interfaces

    This chapter introduces the mechanical construction and interfaces of DNT2Mi. Front panel The front panel of DNT2Mi includes a display, LED indicators, push-button keys, and a local management connector. DN01145897 © Nokia Corporation Issue 2-0 en Nokia Proprietary and Confidential Construction and interfaces 15 (128)

  • Page 16: Indicators And Keys

    The local management interface is located behind the front panel door (see Figure 5). The interface is used to manage DNT2Mi with Macro Service Terminal Emulator (MSTE) running on a PC or with other Nokia management software. If signal 108 (DTR) is on, connecting the Service Terminal Emulator will disconnect DNT2Mi from the remote network management.
