| 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 | |
ATM QoS | rtVBR (real time Variable Bit Rate) – This class is similar to | |
nrtVBR but is designed for applications that are sensitive to | ||
| ||
| with speech activity detection (SAD) and interactive | |
| compressed video. | |
| nrtVBR | |
| 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 | |
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. | ||
| ||
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. |
Encapsulation
The router can be connected to your service provider in any of the following ways.
| Parameter |
| Description |
|
|
|
|
| Dynamic IP Address |
| ISP will automatically provide an IP address. |
|
|
|
|
| Static IP Address |
| ISP has given users an IP address already. |
|
|
|
|
| PPPoE/PPPoA |
| PPPoE (PPP over Ethernet) and PPPoA (PPP over ATM) are |
|
| common connection methods used for xDSL. | |
|
|
| |
|
|
|
|
| Bridge Mode |
| Device will act as modem only equipment to prevent conflict |
|
| with other routers. | |
