Chapter 5 Broadband Table 6 Broadband: Add/Edit: Routing Mode (continued) LABEL Service Category DESCRIPTION Select UBR Without PCR for applications that are non-time sensitive, such as e-mail. Select CBR (Constant 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. Peak Cell Rate 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. Sustainable Cell Rate This field is not available when you select UBR Without PCR. 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 This field is available only when you select Non Realtime VBR or Realtime VBR. 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. PPP Information PPP User Name PPP Password PPPoE Service Name Authentication Mode This field is available only when you select Non Realtime VBR or Realtime VBR. This section is available only when you select Routing in the Mode field and PPPoE or PPPoA in the WAN Service Type field. Enter the user name exactly as your ISP assigned. If assigned a name in the form user@domain where domain identifies a service name, then enter both components exactly as given. Enter the password associated with the user name above. Type the name of your PPPoE service here. This field is available only when you select PPPoE in the WAN Service Type field. The ZyXEL Device supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol). CHAP is more secure than PAP; however, PAP is readily available on more platforms. Use the drop-down list box to select an authentication protocol for outgoing calls. Options are: AUTO: Your ZyXEL Device accepts either CHAP or PAP when requested by this remote node. PAP: Your ZyXEL Device accepts PAP only. CHAP: Your ZyXEL Device accepts CHAP only. MS-CHAP: Your ZyXEL Device accepts MSCHAP only. MS-CHAP is the Microsoft version of the CHAP. 72 P-2601HN(L)-F1 Series User's Guide

Service
Category
Select
UBR Without PCR
for applications that are non-time sensitive,
such as e-mail.
Select
CBR
(Constant 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.
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.
This field is not available when you select
UBR Without PCR
.
Sustainable
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.
This field is available only when you select
Non Realtime VBR
or
Realtime VBR
.
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.
This field is available only when you select
Non Realtime VBR
or
Realtime VBR
.
PPP Information
This section is available only when you select
Routing
in the
Mode
field and
PPPoE
or
PPPoA
in the
WAN Service Type
field.
PPP User Name
Enter the user name exactly as your ISP assigned. If assigned a name
in the form user@domain
where domain identifies a service name, then
enter both components exactly as given.
PPP Password
Enter the password associated with the user name above.
PPPoE Service
Name
Type the name of your PPPoE service here. This field is available only
when you select
PPPoE
in the
WAN Service Type
field.
Authentication
Mode
The ZyXEL Device supports PAP (Password Authentication Protocol) and
CHAP (Challenge Handshake Authentication Protocol). CHAP is more
secure than PAP; however, PAP is readily available on more platforms.
Use the drop-down list box to select an authentication protocol for
outgoing calls. Options are:
AUTO
: Your ZyXEL Device accepts either CHAP or PAP when requested
by this remote node.
PAP
: Your ZyXEL Device accepts PAP only.
CHAP
: Your ZyXEL Device accepts CHAP only.
MS-CHAP
: Your ZyXEL Device accepts MSCHAP only. MS-CHAP is the
Microsoft version of the CHAP.
