5.2.1. Internet 
 
 
 
z ATM VC 
 
Parameter Description 
Virtual Circuit  VPI (Virtual Path Identifier) and VCI (Virtual Channel 
Identifier define a virtual circuit. 
  
VPI 
 VPI is a virtual path determines the way an ATM cell 
should be routed. The VPI is an 8-bit (in UNI) or 12-bit (in 
NNI) number that is included in the header of an ATM 
cell. The valid range for the VPI is 0 to 255. Enter the VPI
assigned by the ISP. 
 
 
  
						

							 25
Parameter Description 
VCI  VCI is the label given to an ATM VC to identify it and 
determine its destination. The VCI is a 16-bit number that 
is included in the header of an ATM cell. The valid range 
for the VCI is 32 to 65535. Enter the VCI assigned by the
ISP.
  
  
ATM QoS  CBR (Constant Bit Rate) – This class is used for 
emulating circuit switching. The cell rate is constant with 
time. Select CBR to specify fixed (always on) bandwidth
 for voice or data traffic.  
 
UBR (Unspecified Bit Rate) – Select UBR for applications 
that are non-time sensitive, such as e-mail. 
 
rtVBR (real time Variable Bit Rate) – This class is similar 
to nrtVBR but is designed for applications that are 
sensitive to cell-delay variation. Examples for real-time 
VBR are voice with speech activity detection (SAD) and 
interactive compressed video. 
 
nrtVBR (non-real time Variable Bit Rate) – This class 
allows users to send traffic at a rate that varies with time 
depending on the availability of user information. 
Statistical multiplexing is provided to make optimum use 
of network resources. Multimedia e-mail is an example of
 nrtVBR. 
  
PCR  Divide the DSL line rate (bps) by 424 (the size of an ATM 
cell) to find the PCR (Peak Cell Rate). This is the 
maximum rate at which the sender can send cells. 
  
SCR  SCR (Sustain Cell Rate) is the average rate, as 
measured over a long interval, in the order of the 
connection lifetime.  
						

							 26
Parameter Description 
MBS  MBS (Maximum Burst Size) refers to the maximum 
number of cells that can be sent at the peak rate. Type 
the MBS, which is less than 65535.

surf the Internet. “Close if idle for xx minutes” is set to 
stop the connection when the network traffic is not 
sending or receiving after an idle time. 
 
  Connect Manually – After you have selected this option, 
please go to Status page. You will see the “Connect”
button, click it and the router will connect to the ISP. If 
you want to stop the connection, please click 
“Disconnect” button.  
  
TCP MSS Option  The “TCP MSS Option” enables the configuration of the 
maximum segment size (MSS) for transient packets that 
traverse a router, specifically TCP segments in the SYN 
bit set, when PPPoE is being used in the network. Please 
specify the MSS range from 100 to 1452 bytes or 0 byte
 as the default value.

NAT  NAT (Network Address Translation), an Internet standard 
that enables a local-area network (LAN) to use one set of 
IP addresses for internal traffic and a second set of 
addresses for external traffic. When NAT is enabled, the 
router will help to make all necessary IP address 
translations for the PC connected to the router to access 
the Internet. 
  
Default Route  When “Default Router” is enabled, all the packets for 
destinations not known by the routers routing table are 
sent to the default route.  By default, it is enabled.
