How to integrate the VSG-1200, ES-3024 and VLC1124L
Here, we will guide you to configure the VSG-1200, ES-3024 and VLC1124L 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.
The DSLAM has two primary components in and of itself: a Splitter Chassis, and a Line Card Chassis.
Each component has a separate purpose and is needed for proper installation.
The splitter chassis contains splitter cards. Each splitter card has three Telco-50 ports, two in the rear,
and one in the front. One rear port acts as the input from the telephone PBX, while the other is the output
port which carries the voice/ data signal to the telephone room’s punchboard and, ultimately, to the
modem in each room. The front port connects directly to the line card in the Line Card Chassis.
