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
