We
would like to make simple LAN installation,
can you show us some application?
|
|
Pls
refer the following LAN application for your
information: |
|
|
|
|
|
|
VLAN
divides a single LAN into'X" number of Virtual
LANs.
VLAN technology creates virtual LANs that utilize
the benefits of independent Lans, while retaining
access to the entire LAN.
A virtual Lan removes selected trafffic and places
it within a virtual LAN
The resutl is less traffic on the entire LAN |
|
|
|
|
|
What
is the difference between Layer2 and Layer3 Swtiching
hub?
|
|
|
The
benefit of Trunking is to be able to group multiple
lower speed links into one higher speed link. For
example, 4 Full-Duplex 100/10Mbps ports operating
as four 200Mpbs links can be used as a single 800Mbps
link.
This is very useful for Switch to Switch, Switch to
Server, and Switch to Router applications. |
|
|
|
|
|
This
option allows the user to limit the amount of broadcast
traffic into the Switch.
User can program the threshold that triggers broadcast
frame filtering. |
|
|
|
|
|
What
is the difference between Layer2 and Layer3 Swtiching
hub?
|
|
|
There
are 7 network Layers-
1. Physical
2. DataLink
3. Network
4. Transport
5. Session
6. Presentation
7. Application
The only difference between Layer 2 and Layer 3 is
that Layer3 switching hub support IP routing function. |

What
are equipment required for a simple SOHO usage? |
|
|
Pls
refer this application. In Taiwan, ADSL modem
is offered by the ISP. You don't to buy ADSL
modem. You just need to apply for the ADSL at
home then the ISP will come to your home or
office to make the instanllation including one
ADSL modem. ADSL can connect to PC directly
There are 2 kinds of applicaton: One is PPPoE
ADSL(Dynamic IP) or Cable(Dynamic IP). Another
is Static IP ADSL. |
|
|
|
|
|
|
Do
we need ADSL modem to use with ADSL service?
|
|
|
Depend
on the ISP's policy. Most of the ISP offers the ADSL
modem to end-user. |
|
|
|
|
|
Infosmart
have some Routers, are they the one to use with ADSL?
|
|
|
Our
broadband router series support xDSL without any problem.
|
|
|
|
|
|
Why
Infosmart using the term xDSL or DSL alone but not
ADSL? What is difference? |
|
|
| ADSL
has speed limited.. Some ISP PROVIDE VDSL OR..
They are different... ADSL is the slowest one...
Please refer to the attachment. For example,
our NFR3100 supports the high throughput over
91Mbps. That is, the NBR1014 can support ADSL,
VDSL.... |

|
|

Please
refer to the attachment. Broadband connectivity have
two different type: xDSL and Cable.
xDSL have many different speed.(512/64,
768/384, ..........12M, 16M, 20M) Cable have 2M, 6M,
8M. |

Major
difference between SOHO router and firewall router?
When should I use firewall router?
|
|
|
Just
for the security issue. Firewall technology can provide
the better protection to prevent unexpected attack
from Internet hacker. |
|
|
|
|
|
What
is major difference between NFR3014 and NVR3015?
|
|
|
The
NFR3014 is a better firewall router. And its throughput
is about 15Mbps. The NVR3015 is a VPN Firewall Router
with Brecis ARM9 CPU. It will create the VPN tunnel
with the remote site via encryption IPSec tunnel mode.
The NFR3014 is a Firewall Router with ADMtech(Conexant)
ARM7 CPU. It won't create any VPN tunnel, just let
the VPN packet pass-through |
|
|
|
|
|
When
I (SOHO user) rent a ADSL service from ISP, what kind
of connection cable they will mostly give to me (using
same telephone cable, or a special kind of cable),
what kind of connector using with that cable?
|
|
|
The
ISP will give you a ADSL modem and a twistpair cable
to connect your LAN card of PC. |
|
|
|
|
|
Any
advise from you with technical view point for ADSL?
|
|
|
The
ADSL connectivity is very popular in the world. Especially
in Japan, Korea, Hongkong and China. They provide
the lower cost and high speed DSL connectivity to
user. That is, user can use the VoIP, video conference
in the smoth speed. |
|
|
|
|
|
What
is the difference between NVR3015 and NFR3014, cause
it seems both are VPN Router??? |

The
comparison between NSR3100PU / NFR3100P |
|
|
SPI
Firewall Router with 2 Print server /4 port Switch.
Pls the following comparison between this SPI firewall
router and NAT firewall router than our NFR3100P.
Normally, NSR3100PU is a very new router in the
market, cause most of router that only provide one
USB print server but our new version of Firewall
router has support up to 2 port print server (1
x USB and 1 Parallel)
