From the
Service Category
drop down select the type of service
The service category selection will be provided by your ISP. The service category defines
five classes of traffic:
UBR Without PCR
(Unspecified Bit Rate without Peak Cell Rate)
UBR service is
suitable for applications that can tolerate variable delays and some cell losses.
Applications suitable for UBR service include text/data/image transfer, messaging,
distribution, and retrieval and also for remote terminal applications such as
telecommuting.
UBR With PCR
(Unspecified Bit Rate with Peak Cell Rate).
Specify a Peak cell Rate Peak cell rate is 1-3442 (cells / sec).
CBR
(Constant Bit Rate)
used by applications that require a fixed data rate that is
continuously available during the connection time.
It is commonly used for
uncompressed audio and video information such as videoconferencing, interactive audio
(telephony), audio / video distribution (e.g. television, distance learning, and pay-per-
view), and audio / video retrieval (e.g. video-on-demand and audio library).
Specify a Peak cell Rate. The Peak Cell Rate is rate is 1-3442 (cells / sec).
Non Realtime VBR
(Non-Real-time Variable Bit Rate)
can be used for data transfers
that have critical response-time requirements such as airline reservations, banking
transactions, and process monitoring.
Specify a Peak cell Rate. 1-3442 (cells / sec).
Sustainable Cell Rate. 1-3442 (cells / sec).
Maximum Burst Size. The maximum number of contiguous cells that can be sent
at the Peak Cell Rate. 1-1000000 (cells / sec)
Realtime VBR
(Real-time Variable Bit Rate)
used by time-sensitive applications such
as real-time video. Rt-VBR service allows the network more flexibility than CBR.
Specify a Peak cell Rate. 1-3442 (cells / sec).
Sustainable Cell Rate. 1-3442 (cells / sec).
Maximum Burst Size. The maximum number of contiguous cells that can be sent
at the Peak Cell Rate. 1-1000000 (cells / sec)
If Quality of Service (QoS) prioritization of IP
traffic is needed, select
Enable IP QoS

On the
PPP Username and Password
page you will need the following information:
PPP Username
: Your account from ISP to access Internet.
PPP Password:
The password assigned by your ISP.
Note:
If you set the username/password to default/default, the modem will redirect the user to
a web page within the modem to change their password when they first log on.
PPPoE Service Name
: Server name of network ISP. No need to set.
Authentication Method
: Authentication mode of network ISP. Default is AUTO
Enable Fullcone NAT
: RFC 3489 defines four types of Network Address Translation
(NAT). Fullcone NAT. As with other types of NAT there is a mapping from a public IP
address to a private IP address. The external public IP address is extended with the
external port. With Fullcone NAT once the mapping is created any external host may
send packets to the private IP address by sending to the external IP address and port.
Other types of NAT have restrictions such as the sending IP address must initially have
had packets sent from the private IP address and port regardless of the external port, or
from the private IP address and the external port.
Enable NAT
must be checked for Fullcone NAT to be used.
MAC Clone
: Clicking the
Clone the PC MAC Address
button will use the MAC address
from the connected PC for the MAC address of the router.
Dial on demand
: When this mode is selected, the connection that has no traffic within
assigned disconnect timeout (e.g. 1 minute) will be automatically disconnected. The
connection will be activated again when traffic arrives. This function is advantageous for
Page 38 / 117
15xx-A1 Family Router Users Guide
38
users who are charged with online time. It should be noticed that some programs
automatically link to Internet. Computer will send data to network when infected by virus.
Connection will not be disconnected under these data streams.
Inactivity Timeout
: When
Dial on demand
is selected, this input box indicates that after
how long the connection will be disconnected in the absence of traffic. If the value is 0,
connection will not be disconnected.
MTU
: the Maximum transmission unit (MTU) value may be set for your needs. Higher
MTU can provide for a more efficient link because each packet will carry more data while
the overhead in the packet such as header information does not get larger with the size
of the packet. So the bulk throughput on the link will go up. Generally a large packet size
can occupy the time on the link, so the higher MTU can increase lag time and minimum
latency which is not appropriate for all applications.
Manual Connect
: connect/disconnect PPPoE connection manually
PPP IP extension
: Allows only one PC on the LAN. The public IP address assigned by
the remote using the PPP/IPCP protocol is actually not used on the WAN PPP interface.
Instead, it is forwarded to the PC's LAN interface through DHCP.
Only one PC on the LAN can be connected to the remote since the DHCP server within
the ADSL gateway has only a single IP address to assign to a LAN device. NAT and
firewall are disabled when this option is selected. The ADSL gateway becomes the
default gateway and DNS server to the PC through DHCP using the LAN interface IP
address. The ADSL gateway extends the IP subnet at the remote service provider to the
LAN PC. That is, the PC becomes a host belonging to the same IP subnet. The ADSL
gateway bridges the IP packets between WAN and LAN ports, unless the packet is
addressed to the gateway's LAN IP address.
Enable NAT
: To define NAT services in the
Advanced Setup | NAT
screens, NAT must
be enabled.
NAT Public Address
(available if NAT is enabled).
Automatic
means the modem will
use pubic IP addresses provided by the network;
Menu IP addresses
means that the
modem will use the addresses you specify.
Enable Firewall
: Enables Firewall.
Use Static IPv4 Address
: Defines a static IP address (v4) which you enter in the
IPv4
Address
text box which is displayed when the
Use Static IPv4 Address
check box is
selected.
Enable PPP Debug Mode
: Used to debug PPPoE issues. Use only when instructed by
your ISP.
Enable KeepAlive
: Enables/disables TCP keep alive packets.
Bridge PPPoE Frames Between WAN and Local Ports
: By default the bridge PPPoE
frame between WAN and local ports is on.
This allows a PC behind the modem to be the
PPPoE termination point. PPPoE authentication is passed on to the PC instead of to the
router. If there are multiple PCs then, each one will have a PPPoE authentication. Note
that this option is not applicable for PPPoA.
Enable IGMP Multicast Proxy
: Configures the router for IGMP snooping so the router
can keep limit multicast traffic.
