It is the responsibility of the network operator to provide end-to-end connectivity
throughout the network on these virtual channels. Due to regional differences or
because of the specific policy of your local operator, specific VPI/VCI values may be
required. In this case, the network operator, ISP or corporate administrator will
provide the correct values.
The VPI can range from 0 to 15, VCI from 32 .. 511.
QoS Book The QoS Book table displays following parameters:
Name :
The name of the new QoS entry.
txctd
:
The name of the Connection Traffic Descriptor (CTD) for the transmit
(upstream) direction.
rxctd
:
The name of the CTD for the receive (downstream) direction.
Interfaces The Interfaces tab allows you to configure:
Name :
The name of the ATM interface to be configured.
Destination
:
The WAN destination for this ATM interface. Typically, an ATM phonebook
entry.
Qos name :
The name of the Quality of Service (QoS) book entry to apply on this ATM
interface.
Encapsulation
:
The type of encapsulation to be used for this ATM interface. Choose between:
llc : Logical Link Control (LLC) / Sub Network Access Protocol (SNAP)
vcmux : Virtual Channel MUltipleXing (VCMUX).
auto : the SpeedTouch™ will determine the encapsulation method to use.
Number of retries :
A number between 0 and 65535. Represents the number of times the
SpeedTouch™ retries to set up a WAN connection before giving up.
FCS
:
Enable or disable the inclusion of the Ethernet Frame Check Sequence (FCS) in
the packet header on the WAN side (only used for llc encapsulation for mac).
Upper layer protocol :
Select the Upper Layer Protocol (ULP) for this interface. Choose between:
ip
(for a Routed IPoA interface).
mac
(for a Bridged Ethernet, Routed ETHoA, Bridged PPP over Ethernet
(PPPoE), Routed PPPoE or a PPPoE Relay interface).
ppp
(for a Routed PPP over ATM (PPPoA) interface).
If your SpeedTouch™ is equipped with an ATMF-25.6Mb/s interface, VPI 0 to
7 (included) are cross-connected between the DSL port and the ATMF-
25.6Mb/s port. Unless these cross-connects are deleted using the CLI, these
VPI values (0 ... 7) cannot be used.
This parameter is normally left disabled.
