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
MSC Mode: multiple services over one connection. With the MSC Mode setting a single
PVC layer 2 interface is created upon which multiple WAN services may be created
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)
If Quality of Service (QoS) prioritization of IP traffic is needed, select Enable IP QoS
