How to integrate the VSG-1200, ES-2008 and VES-1124
Here, we will guide you to configure the VSG-1200, ES-2008 and VES-1124 step by step. You can refer
these procedures to finish the environment easily, and provide the Internet service to your customer.
Before You Begin
Before you begin installation, it’s important to understand how the equipment is designed to work and
how it should be installed.
Why VDSL?
VDSL stands for Very fast Digital Subscriber Line. It is a form of DSL that allows for traffic throughput of
up to 15Mbps.
Although this is not as fast as the speed of Ethernet, which is usually 100Mbps and now available up to
1000Mbps, it can travel farther. Ethernet is limited to a maximum cable length of about 300 feet, whereas
VDSL can transmit on cable lengths up to about 4500 feet.
Like ADSL, VDSL allows use of voice and data on the same 2-conductor line. This means that a hotel
can leverage their existing cable infrastructure to provide guests with high-speed Internet, without the
additional cost of installing new wiring. Each room only needs a single pair of wire for both voice and
high-speed data.
Unlike ADSL, all configurations to the remote modems are done from the VDSL switch. This means that
there is less time spent configuring units, and fewer chances for miss-configuration. Customers also
cannot accidentally change the settings on the modem, since the VDSL switch programs the modem itself.
VDSL basics
To install VDSL, you must have two pieces of equipment:
A VDSL concentrator, also known as a VDSL Digital Subscriber Line Access Multiplexer
(DSLAM) or VDSL Central Office Equipment (COE)
A VDSL modem, also known as a VDSL Customer Premise Equipment (CPE)
The DSLAM is normally mounted inside a telephone closet, along with the hotel’s existing telephone PBX.
In each room, a VDSL modem is installed to which customers connect their computers via Ethernet port.
Normal DSLAMs require multiple chassis and cards to operate. However, the VES-1124 is a self-
contained DSLAM capable of connecting up to 24 VDSL modems to your Internet connection. The VES-
1124 requires no additional chassis or splitters for operation.
In each room a VDSL modem is placed. The modem has an input from the wall outlet, and two outputs:
one phone port for an analogue telephone, and an Ethernet port for a computer connection. Because all
of the parameters are programmed in DSLAM, the modem has no settings to configure.
