Dynamix UM-V2 VDSL LAN Extender

User Manual, V100

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

Cost effective bridge function to connect two Ethernet LAN

Support flow control on Fast Ethernet port via PAUSE frame or Back Pressure

IEEE 802.1Q VLAN tag transparent

Easy installation via simple plug-and-play

Selectable 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.

Selectable 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.

Selectable 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.
