NV-802S 8 Ports VDSL2 Managed IP DSLAM with 2 Giga Ethernet USER’S MANUAL Ver.B2
systems, are not limited to short loops or MTU/MDUs only, but can also be used for medium range applications.
VDSL2 IP DSLAM
The NV-802S utilize Lantiq(Infineon) Vinax VDSL2 Chipset, which is a VDSL2 IP DSLAM that aggregates 8 ports into Giga Ethernet
uplinks for high-speed data/Internet services.
Based on DMT VDSL2 technologies, NV-802S 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
NV-802S. Alternatively, multiple NV-802S can be connected to another LAN switch to from a two-tier configuration, thus supporting a
lot more subscribers. The NV-802S 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 telecom.
The NV-802S provides the important features necessary for robust networks
Key features and benefits :
Jumbo packet up to 9k byte: 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
