6.3 The Advanced Screen
Use the
Advanced
screen to enable or disable ADSL over PTM, Annex M, DSL PhyR, and SRA (Seamless
Rate Adaptation) functions. The XMG supports the PhyR retransmission scheme. PhyR is a retransmission
scheme designed to provide protection against noise on the DSL line. It improves voice, video and data
transmission resilience by utilizing a retransmission buffer.
Type
Select
ADSL over ATM
as the interface that you want to configure. The XMG uses the ADSL
technology for data transmission over the DSL port.
Mode
Select
Bridge
when your ISP provides you more than one IP address and you want the
connected computers to get individual IP address from ISP’s DHCP server directly. If you select
Bridge
, you cannot use routing functions, such as QoS, Firewall, DHCP server and NAT on traffic
from the selected LAN port(s).
ATM PVC Configuration (These fields appear when the
Type
is set to
ADSL over ATM
.)
VPI
The valid range for the VPI is 0 to 255. Enter the VPI assigned to you.
VCI
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.
Encapsulation
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
Encapsulation
field.
•
VC/MUX:
In VC multiplexing, each protocol is carried on a single ATM virtual circuit (VC). To
transport multiple protocols, the XMG 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.
Service
Category
Select
UBR Without PCR
for applications that are non-time sensitive, such as e-mail.
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.
VLAN
This section is available only when you select
ADSL/VDSL over PTM
in the
Type
field.
Active
Select
Enable
to enable VLAN on this WAN interface.
802.1p
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame that
contains bits to define class of service.
Select the IEEE 802.1p priority level (from 0 to 7) to add to traffic through this connection. The
greater the number, the higher the priority level.
802.1q
Type the VLAN ID number (from 0 to 4094) for traffic through this connection.
OK
Click

to save your changes.
Cancel

to exit this screen without saving.
