    MPGHDSL is the N 64K high-speed digital loop transmission device researched and developed by Maipu Communication, which is convenient in long-distance transmission and low-bit error rate.


    MPGHDSL Modem (Front)

    Key Features
    • Speedy digital transmission
      • GHDSL realizes N 64KbpsN=1~32 two-way user digital transmission on one pair of line
    • Distance
      • For the local telephone cable, its relay-free transmission distance reaches 3.6~6.2Km (0.4mm wire diameter)
    • Advanced Technology
      • GHDSL adopts advanced digital signal processing technology (self-adapt equalization and echo cancel) and super-scale integrated circuit technology with high reliability and good stability
    • Economical & Practical
      • GHDSL is applicable to all non-loading loops and does not require the line repeater and its corresponding devices
      • No need for engineering design and cable renovation
      • Reduces project investment
    • Flexible Operation
      • GHDSL can quickly open all kinds of telecom services on all available cables as per the requirement. Installation and removal are very convenient.
    • Good Performance
      • GHDSL bit error rate reaches 10-8 improving transmission quality of optical fiber
      • Applicable to all kinds of telecom services for transmitting of frequency, data and image
    • Good Maintainability
      • GHDSL possesses comparatively strong functions of performance monitoring, diagnose and maintenance management
      • Users conveniently acknowledge with the status of equipment startup, operation status, line failure and 2M port failure on equipment panel
      • When the system fails, it conveniently locates the failure through loop test
      • Connects with PC as per requirement to realize the high-level maintenance management
    • NMS
      • GHDSL can be managed, configured or loop tested from central AccessManager (network management software), while it is connected with MP94GHDSL card in MP9400 series
