Note
Measuring points of the working temperature and humidity of
theVG2000 series VoIP gateway in the equipment room mean the
values measured 1.5m above the floor and 0.4 m from the front of
the VoIP gateway when there are no protection boards;
The short-term working condition means less than 48h work
continuously and less than accumulative 15-day work in a year.
Extreme severe work environment generally means that
abnormal temperature and humidity may occur when the air
conditioning system of the equipment room is faulty. In this
situation, the gateway should restore to normal work range within
5h.
1.1.2 Cleanliness Requirement
Dust is harmful for the VG2000 series VoIP gateway operation.
Dust causes electrostatic absorption, which makes the poor
contact of metal connectors. Electrostatic absorption appears
especially when the temperature and humidity are lower, which
affects the device life and easily causes communication fault.
1.1.3 Anti-static Requirement
Although VG2000 series VoIP gateway adopts lots of anti-static
measures, it will still cause damage to the circuit and even the
entire device when the static exceeds a certain limit.
In the VG2000 series VoIP gateway communication network,
the electrostatic induction is mainly from two aspects: outside
electric field such as outdoor high voltage transmission line and
lightning and thunder, and interior system such as indoor
environment, floor material, and entire device structure.
