Network time server, a professional manufacturer of Jinan Weishang, Shandong
Network time server
is a layer 1
network time server independently developed and produced by Jinan Weishang Electronics Co., Ltd., which can It provides accurate and secure network synchronization time information inside the firewall. It uses
signal as the time synchronization source. This product integrates
receiving module and high-performance industrial-grade motherboard, which can be obtained through
network
Time information can be easily deployed anywhere with
signals, and is especially suitable for deployment in network communication equipment rooms where it is inconvenient to deploy outdoor
antennas. This saves you the hassle and extra expense of installing a rooftop antenna. In addition, because the antenna is conveniently placed indoors, damage to equipment caused by lightning weather can be completely eliminated.

One layer for most
Network time servers need to install rooftop antennas and require good visibility outdoors, but Weishang
products are not subject to this restriction because it obtains
time information through
mobile phone communication networks, which means This means that the antenna can be installed anywhere where there is a
signal, even inside the building, and it can provide
as accurate and stable
time synchronization information. In addition, because the antenna is conveniently placed indoors, damage to equipment caused by lightning weather can be completely eliminated.
Excellent network information security
Weishang
Network time server
Excellent network information security can resist any network attack. In general, only a few settings are required for the device and in most cases it is configured only once. All unnecessary protocols and services have been eliminated within the device to avoid exposing network security vulnerabilities. You can change the key settings of the network through the
or
protocols, and you can also monitor the device's alarm
status information through the
,
,
and other protocols. , customers with higher requirements for network security can disable all risky protocols such as
,
,

or restrict the use of
,
Permissions can also restrict
access to designated hosts.
