VDSL Point to Point Solution
The VDTU-101/201 works as Ethernet to/from VDSL subscriber-site conversion bridge. The
VDTU-101/201 uses QAM-based 4-band VDSL technologies. Which supports max distance
1.9Km (6333ft) at 5M/5M or 1.3Km (4333ft) at 15M/15M, or 800m(2666ft) at 25M/25M
symmetrical data service. The VDTU-201 also works with VRM-308/VRM-324 VDSL IP
DSLAM, together to form a cost-effective solution for services such as remote lecturing,
telemedicine, video conferencing, Video-on-Demand (VoD), IP-TV etc. Internet access, and
various high-speed data applications.
The front-panel provides LED indications of system and interface status. The built-in
POTS/ISDN splitter allows a standard POTS phone or ISDN device to be connected. Full or
half-duplex mode of LAN operations is automatically sensed and configured. VDSL link rates
are configured by local Modem or IP DSLAM over auto speed function.
Therefore, VDTU-101/201 supports auto-speed, plug & play operations on the subscriber-site,
and are part of an ideal solution for delivering cost-effective, high-performance
broadband/multimedia services to Multi-Dwelling Units (MDU) and Multi-Tenant Units (MTU)
environments such as hotels, campus, hospitals and telecom.

2. Installation
Hardware Installation
This chapter describes how to install the VDTU-101 & 201 MODEM and establishes
network connections. You may install the VDTU1-101 & 201 MODEM on any level
surface (e.g, a table or shelf). However, please take note of the following minimum site
requirements before you begin.
2.1 Pre-installation Requirements
Before you start actual hardware installation, make sure you can provide the right
operating environment, including power requirements, sufficient physical space, and
proximity to other network devices that are to be connected. Verify the following
installation requirement:
zPower requirements: DC5V/1Aor above.
zThe VDTU-101 & 201 MODEM should be located in a cool dry place, with at least
10cm/4in of space at the front and back for ventilation.
zPlace the VDTU-101 & 201 MODEM out of direct sunlight, and away from heat
sources or areas with a high amount of electromagnetic interference.
zCheck if network cables and connectors needed for installation are available

General Rules
Before making any connections to the MODEM, note the following rules:
zEthernet Port (RJ-45)
All network connections to the Modem Ethernet port must be made using Category
5 UTP for 100Mbps; Category 3,4 UTP for 10Mbps
No more than 100 meters of cabling may be use between the MUX or HUB and an
end node.
zPhone Port (RJ-11)
All Phone set connections to the RJ-11 Port made using 24~26 Gauge phone wiring.
Connecting the MODEM
The Modem has one Ethernet port which support connection to Ethernet operation. The
devices attached to these ports must support auto-negotiation or 10Base-T OR
100Base-TX unless they will always operate at half duplex.
Use any of the Ethernet ports to connect to devices such as NIC, Switch, bridge or router.
You can also connect to another compatible Modem to an RJ-45 port on the other device.
The RJ11 Line port is used to connect to the wall RJ-11 modular socket (outlet) which is
connect to VDSL 4-Band CPE Modem side (Point to point solution)
The RJ11 Phone port of the Modem can connected to a telephone and a computer sharing
one telephone wire for making calls and accessing the internet at the same time.
Connecting the RJ-11/RJ-45 Ports
1. The Modem’s RJ-11 ports supports max distance 1.9Km at 5M/5M or max speed
25M/25M symmetrical and distances up to 800m data service across existing
phone wiring, without interfering with standard voice transmissions, easy-to-use
does not require the installation of any additional wiring. Every RJ-11 modular
phone jack in the home can become a port on the LAN. Networking devices can be
installed on a single telephone wire that can span within 1.9Km or 800m (depend
on speed) between the two farthest points. (Figure 1.0).
2. VDTU-101/201 Modem has embedded Splitter between every VDSL side (Line) and
POTS (Phone) side. It permit you to deliver broadband service on the same lines as
Plain Old Telephone Service (POTS), PBX, ISDN traffic and VDSL Signal.

3.The RJ-11 port support max distance 1.9Km at 5M/5M or max speed 25M/25M
symmetrical and distances up to 800m data service. When inserting a RJ-11 plug,
be sure the tab on the plug clicks into position to ensure that it is properly seated.
4.Do not plug a RJ-11 phone jack connector into the Ethernet port (RJ-45 port). This
may damage the modem. Instead, use only twisted-pair cables with RJ-45
connectors that conform to Ethernet standard.
Notes:
1.Be sure each twisted-pair cable (RJ-45) does not exceed 100 meters (333 feet).
2.RJ-11 port use 24 ~ 26 gauge phone wiring, we do not recommend 28 gauge or
above.
3.We advise using Category 3,4,5 cable for Cable Modem or Router connections to
avoid any confusion or inconvenience in the future when you upgrade attached to
high bandwidth devices.
4.Be sure phone cable has been installed when VDTU-101 and VDTU-201 will be
power on.

4. Firmware Description
Auto Speed function description.
VDTU-101 is a 4band VDSL solution which supports auto speed function, they can
support 5M/15M/25M symmetrical data service depend on installing environment, they
will do auto speed function while phone cable be re-plug in between VDTU-101 and
VDTU-201, or both be re-power on. VDTU-101 will try to link with 25M/25M mode first, if
link fail will auto speed down to 15M/15M mode second, and if link fail again will auto
speed down to 5M/5M, then stay on this mode until re-plug in phone cable or re-power on
both.
Speed mode limitation :
5M/5M mode within 1.9km (6333ft)
15M/15M mode within 1.3km (4333ft)
25M/25M mode within 800m (2666ft)
Note : We recommend phone cable which must meet Cat. 3 standard or above and
without clustering, otherwise the above guarantee will be void.
Engineering Functions :
These functions is for maintaining and troubleshooting such as firmware upgrade,
command line, SNR indicator, Ethernet and VDSL port setting and status monitor
and so on. And it is supporting plug and play, so end user doesn’t have to need it.
