EX5301, EX5401-B0, EX5501, AX7501 and PX7501)
Use this screen to change your Zyxel Device's Internet access settings. The summary table shows you the
configured WAN services (connections) on the Zyxel Device. Use information provided by your ISP to
configure WAN settings.
Note: The difference of the broadband screens between EX3300-T0/EX3301-T0/EX5300-B3/
EX5301/EX5401/EX5501 and AX7501/PX7501 is the type of connection available. EX3300-
T0/EX3301-T0/EX5300-B3/EX5301-B3/EX5501-B0 have Ethernet connections. EX5401-B0
has Ethernet and SFP connections. AX7501 and PX7501 have AON or PON connection.

DESCRIPTION
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic).
Enter the VCI assigned to you.
Select the method of multiplexing used by your ISP from the drop-down list box. Choices are:
• LLC/SNAP-BRIDGING: In LCC encapsulation, bridged PDUs are encapsulated by identifying the
type of the bridged media in the SNAP header. This is available only when you select IPoE or
PPPoE in the Select DSL Link Type field.
• VC/MUX: In VC multiplexing, each protocol is carried on a single ATM virtual circuit (VC). To
transport multiple protocols, the Zyxel Device needs separate VCs. There is a binding between a
VC and the type of the network protocol carried on the VC. This reduces payload overhead
since there is no need to carry protocol information in each Protocol Data Unit (PDU) payload.
Select UBR Without PCR for applications that are non-time sensitive, such as email.
Select CBR (Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice or data traffic.
Select Non Realtime VBR (non real-time Variable Bit Rate) for connections that do not require
closely controlled delay and delay variation.
Select Realtime VBR (real-time Variable Bit Rate) for applications with bursty connections that
require closely controlled delay and delay variation.
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.
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 (MBS) refers to the maximum number of cells that can be sent at the peak rate.
Type the MBS, which is less than 65535.
