and Built-in Switch
User Manual

Figure 36. Configuring Dynamic IP WAN connection. The expert settings mode. The
ATM
and
IP
sections.
Parameter
Description
Connection name
A name for connection for easier identification.
ATM
VPI
Virtual Path Identifier.
The valid range is from 0 to 250.
VCI
Virtual Circuit Identifier.
The valid range is from 32 to 65535.
Encapsulation Mode
Select
LLC
or
VC
from the drop-down list.
QoS
A class of traffic for this connection.
UBR
(
Unspecified Bit Rate
): The UBR service is used for applications
that allow various delays and losses of packets. It is appropriate to
use the UBR service for text/data/image transfer applications, as
well as messaging, distribution, retrieval, and remote terminal
applications.
UBR With PCR
(
Unspecified Bit Rate with Peak Cell Rate
): The UBR service is
used for applications that allow various delays and losses of packets.
The Peak Cell Rate is a determining factor in how often cells are
sent in an effort to minimize lag or jitter caused by traffic

inconsistencies. When you select this value from the drop-down list,
the
Peak Cell Rate
field is displayed. Specify a required value (in
cells per second).
CBR
(
Constant Bit Rate
): This service is used for applications that
require a constant data rate. It is mostly used for transferring
uncompressed audio and video, e.g. videoconferencing, interactive
audio (telephony), audio/video distribution (television, distance
education, e-shops), and retrieval (video-on demand, audio
libraries). When you select this value from the drop-down list, the
Peak Cell Rate
field is displayed. Specify a required value (in
cells per second).
Non Realtime VBR
(
Non-Real-time Variable Bit Rate
): This service can be used for
transferring data that have critical response-time requirements, e.g.
air ticket booking, bank transactions, and process monitoring. When
you select this value from the drop-down list, the
Peak Cell Rate
,
Sustainable Cell Rate
, and
Maximum Burst Size
fields are
displayed. Specify required values.
Realtime VBR
(
Real-time Variable Bit Rate
): This service is used for delay-
sensitive applications such as real time video. The Rt-VBR provides
higher network flexibility than the CBR service. When you select
this value from the drop-down list, the
Peak Cell Rate
,
Sustainable Cell Rate
, and
Maximum Burst Size
fields are
displayed. Specify required values.
IP
Vendor ID
The identifier of your ISP.
Optional

Parameter
Description
Ethernet
MTU

agreement.
Also you can set the address of a device connected to the router's
LAN at the moment. To do this, select the relevant value from the
drop-down list (the field will be filled in automatically).
