VDSL2 IP DSLAM
The VS-2400S H is a VDSL2 IP DSLAM that aggregates 24 ports into Giga Ethernet uplinks for high-speed data/Internet services.
Based on DMT VDSL2 technologies, VS-2400S extends data service with line rate of solution for services such as remote lecturing,
telemedicine, video conferencing, Video-on-Demand (VoD), IP-TV, Internet access and other various high-speed data applications.
When the number of subscribers increases, the second uplink Giga Ethernet interface can be used to daisy chain to another
VS-2400S. Alternatively, multiple VS-2400S can be connected to another LAN switch to from a two-tier configuration, thus supporting
a lot more subscribers. The VS-2400S is an ideal solution for delivering cost-effective, high-performance broadband/multimedia
services to Multi-Tenant Units (MTUs) or Multi-Dwelling Units (MDUs) such as hotels, campus, hospitals and sscom.
The VS-2400S provides the important features necessary for robust networks
Key features and benefits :
Jumbo packet up to 9k bytes:
In computer networking, jumbo frames are Ethernet frames with more than 1500 bytes of
payload. Conventionally, jumbo frames can carry up to
9000 bytes
of payload, but variations exist and some care must be
taken when using the term.
The original 1500-byte payload size for Ethernet frames was used because of the high error rates and low speed of
communications. Thus, if one receives a corrupted packet, only 1500 bytes (plus 18 bytes for the frame header and other
overhead) must be re-sent to correct the error. However, each frame requires that the network hardware and software
process it. If the frame size is increased, the same amount of data can be transferred with less effort. This reduces CPU
utilization (mostly due to interrupt reduction) and increases throughput by allowing the system to concentrate on the data in
the frames.
IEEE 802.1q Q-in-Q VLAN for performance & security:
The VLAN feature in the switch offers the benefits of both security
