Advanced Setup
This section contains advanced setup settings. To create a connection you need to define the
Layer 2 interface and the WAN service.
Configuration Types
ADSL is an ATM based technology. The 65xx family of routers support Bridging and Ethernet
over ATM (EoA) configurations and ATM based configurations:
Bridging
Bridging (Layer 2 MAC addressing); uses Ethernet frames.
PPPoE
Point to Point Protocol over Ethernet; encapsulates PPP packet in Ethernet. (RFC 2516)
IPoE
IP over Ethernet (Layer 3 Internet Protocol addressing in Ethernet frames)
PPPoA
Point to Point Protocol over ATM, encapsulates PPP frames in ATM adaption layer 5 (AAL5)
packets.
IPoA
IP over ATM (Layer 3 Internet Protocol addressing in AAL5 packets
To configure a connection, you first configure the connection type. EoA, PPPoA, or IPoA.
1.
Add a Layer 2 interface and select the connection type.
EoA is used for PPPoE, IPoE and Bridge connections. PPPoA and IPoA are AAL5 based
connections
2.
Set the WAN interface
The WAN interface options to select are determined by the Layer 2 interface type.
Add an ATM Layer 2 Interface
1.
In the left hand menu pane, click
Advanced Setup
.
2.
Under Advanced Setup, click Layer2 Interface then ATM Interface, then click the
Add
button.
3.
In the
VPI
and
VCI
text boxes enter appropriate VPI/VCI numbers.
VPI/VCI (Virtual Path Identifier/Virtual Circuit Identifier) values essentially define the “pipe”
which sends data from the upstream device to the modem/router. The VPI/VCI values will be
given to you by your ISP.
4.
Under
Select DSL Link
Type
select the appropriate DSL link type:

5.
For the EoA options you may select a connection mode:
Default Mode
: a single service over the one connection
VLAN MUX Mode
: multiple VLAN services over the one connection
6.
From the
Encapsulation Mode
drop down select the appropriate option
:
For
EoA
options (PPPoE, IPoE, Bridge) select
LLC/SNAP BRIDGING
For
PPPoA
select
VC/MUX
For
IPoA
select
LLC/SNAP ROUTING
7.
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)
8.
If using UBR without PCR, select the
IP Quality of Service (QoS) algorithm
. Either
Strict
Priority
or
Weighted Fair Queuing.
9.
Click
Apply/Save
to add the appropriate WAN service
Add an Ethernet Layer 2 Interface
The system allows you specify any Ethernet interface as a WAN interface.
