Chapter 1 Introduction
Dynamix UM-V2 VDSL LAN Extender is a long reach Ethernet media converter with one
Ethernet port (RJ-45 connector) and one VDSL port (RJ-45 connector) It is a bridge mode
modem, well accommodating VDSL2 (Very-high-data-rate Digital Subscribe Loop)
technologies to extend Ethernet service over single-pair phone line. Supporting both
symmetric and asymmetric transmission, it can reach up to 100/75 Mbps bandwidth (line
rate) within 300M or 10/10 Mbps (line rate) for 1 Km long range connections. By providing
ultra-high speed, Dynamix UM-V2 VDSL LAN Extender makes your telephone line achieve
its best performance than before. It has the advantage of minimum installation time (simply
as plug-n-play) and minimum expense by allowing video streaming and data to share the
same telephone pair without interference.
1.1 Features
ØCost effective bridge function to connect two Ethernet LAN
ØSupport flow control on Fast Ethernet port via PAUSE frame or Back Pressure
ØIEEE 802.1Q VLAN tag transparent
ØEasy installation via simple plug-and-play
ØSelectable CPE and CO mode via DIP switch:
Two working modes are built in the same unit, which keep the flexibility of
installation and easy provision of service but lower inventory of service provider.
ØSelectable fast and interleaved mode:
Fast mode guarantees a minimum end to end latency less than1 ms. Interleaved
mode provides impulse noises protection for any impulse noise with a duration
less than 250 us, Interleaved mode has a maximum end to end latency of 10 m
sec. Interleaved mode is the default mode.
ØSelectable target data rate and target SNR margin:
User has the ability to select fixed SNR margin (9 dB) or fixed target data rate.
When fixed SNR margin is selected, the systems will maintain the SNR margin at
9 dB across all usable loop length. When fixed target data rate is selected, the
system will lock the data rate up to 50 Mbps/30 Mbps whenever the calculated
SNR margin is higher than 9 dB. This gives best system stability and is the
default mode.
