■
Manual - Start in Last State
means that after re-booting the Router,
the Internet connection will stay in the previous condition before
the reboot.
5
If you want your Router to automatically disconnect from the Internet
after a period of inactivity, specify a time in the
Idle Time (Minutes)
field.
(Enter a value of 0 to disable this timeout).
6
Enter the
Maximum Transmission Unit (MTU)
value supplied by your ISP. If
you do not know this, leave it at the default value.
7
The Router supports the IP Control Protocol (IPCP) Subnet Mask Support
feature, check the
IPCP subnet
checkbox to enable it.
8
To use the IPCP Subnet Mask Support for the DHCP clients, check the
IPCP Subnet Populate DHCP Server
checkbox.
9
Enter the VPI and VCI values provided by your ISP in the
VPI
and
VCI
fields. You can click
Auto Search
to automatically find out this
information.
10
Select the encapsulation type (LLC or VC MUX) in the
Encapsulation
field.
This information should be provided to you by your ISP.
11
Select the type of Quality of Service (CBR, UBR or VBR) in the QoS field.
■
CBR (constant bit rate): the CBR service class is intended for
real-time applications, for example, those requiring tightly
constrained delay and delay variation, such as voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service.
■
VBR (variable bit rate): QoS class defined by the ATM Forum for
ATM networks. VBR is subdivided into a real time (RT) class and
non-real time (NRT) class. VBR (RT) is used for connections in which
there is a fixed timing relationship between samples. VBR (NRT) is
used for connections in which there is no fixed timing relationship
between samples, but that still need a guaranteed QoS. Compare
with ABR, CBR, and UBR.
■
UBR (unspecified bit rate): the UBR service class is intended for
delay-tolerant or non-real-time applications, for example, those
which do not require tightly constrained delay and delay variation,
such as traditional computer communications applications. The
UBR service may be considered as "best effort service".
12
Enter the PCR/SCR/MBS values. This information should be provided to
you by your ISP.
