7.6 WAN More Connections
The ZyXEL Device allows you to configure more than one Internet access connection. To
configure additional Internet access connections click Network > WAN > More
Connections. The screen differs by the encapsulation.
ATM QoS Type Select CBR (Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice
or data traffic. Select UBR (Unspecified Bit Rate) for applications that are non-time
sensitive, such as e-mail. Select VBR-RT (real-time Variable Bit Rate) type for
applications with bursty connections that require closely controlled delay and delay
variation. Select VBR-nRT (non real-time Variable Bit Rate) type for connections
that do not require closely controlled delay and delay variation.
Peak Cell Rate Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak Cell
Rate (PCR). This is the maximum rate at which the sender can send cells. Type the
PCR here.
Sustain Cell Rate The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can be
transmitted. Type the SCR, which must be less than the PCR. Note that system
default is 0 cells/sec.
Maximum Burst
Size
Maximum Burst Size (MBS) refers to the maximum number of cells that can be sent
at the peak rate. Type the MBS, which is less than 65535.
Zero
