Type

is the protocol used for connecting to your broadband Service Provider.

The available

options depend on the selection of the

WAN port

parameter. Please consult your Service Provider

about the option that must be selected.

The parameters appearing on the rest of the configuration page, depend mainly on the values of

the

WAN port

and

Type

parameters.

ATM Options

These parameters appear only for ADSL connections and define the ATM PVC over which the WAN

connection will be performed. From the drop-down list you can select an existing PVC or configure a

NEW

one providing values for the

VPI

,

VCI

and

Encapsulation

parameters.

When multiple DSL ports are present

(optional feature)

, the

P

x

characters indicate which DSL port

this ATM-PVC refers to (e.g.

P1

is port 1).

802.1Q VLAN

In case of

PPPoE

or

EoA

ADSL connections and of any type of VDSL or Ethernet connection, the Ethernet

frames can optionally by tagged with a 802.1Q VLAN ID. This way, multiple connections can share the

same ATM PVC, VDSL or Ethernet WAN port, separated at the Ethernet level using normal Ethernet

VLANs.

In order to activate this functionality for the connection, select the

Enabled

checkbox and

specify the corresponding

VLAN ID

. Valid

VLAN ID

values are

1

to

4094

.

Additionally, all outgoing Ethernet frames through this connection can also be marked with a specific

802.1p Class of Service (

CoS

) value for Quality of Service on the Ethernet level. Valid

VLAN CoS

values

are between

0

and

7

.

Modem Options

This provides the parameters required in the case of broadband access through a modem connected

to the USB port of the OxyGEN

mini

Office

(optional feature)

.

1.

External modem

is the USB modem used for this connection, or

ANY MODEM

in order to use the

first modem detected. Refer to section

External Modems

on page 67 for a description of the

configurations steps required in order to define an external modem.

2.

Profile

is the set of parameters used in case of a USB 3G modem. Pre-defined sets of parameters can

be selected, whereas

CUSTOM

allows the user to manually enter the modem-related parameters.

3.

APN

is the Access Point Name used to determine how the 3G modem of the OxyGEN

mini

Office

communicates via the GSM network to the Service Provider’s network.

4.

Init string

is the modem initialization string.

5.

Dial string

is the modem dial string.

WARNING

Please refer to your GSM/3G Service Provider in order to find the correct

APN

,

Init string

and

Dial string

values, in case you do not use one of the pre-defined profiles.

IPv6 Options

In case IPv6 functionality is enabled in OxyGEN

mini

Office (please refer to section

IPv6 Addresses

), there

are the following options:

1.

Operation

may be defined between plain

IPv4

, plain

IPv6

and

Dual Stack

.

2.

IPv6 Address

may be selected between

Auto Configuration

, which allows for WAN interface to

be autoconfigured for an IPv6 prefix through the remote server and

Link Local

, where the WAN

interface obtains only a link-local IPv6 address.

Figure 6.7: IPv6 Options

PPP Options

These are the PPP authentication parameters required in the case of a

PPPoE

,

PPPoA

or

USB PPP

connection:

1.

Username

is the username used for the PPP negotiation with your Service Provider. Please consult

your Service Provider about the correct value.

2.

Password

is the password used for the PPP negotiation with your Service Provider. Please consult

your Service Provider about the correct value.

3.

MTU size

is the Maximum Transmission Unit (MTU) size in bytes of the PPP connection interface.

4.

PPPoE passthrough

enables or disables the transparent forwarding of PPPoE sessions initiated from

a LAN host (e.g. a PC) towards the WAN in case of

RFC 1483/2684 bridged

ATM PVCs, VDSL or

Ethernet WAN

connections.

5.

Dial On Demand

enables or disables the "on-demand" functionality of the PPP session, to be

automatically activated when there is need for data traffic and deactivated when the connection

is idle.

WARNING

Do not modify the default MTU value, unless instructed so by your Service Provider. Invalid

MTU values can lead to loss of connectivity or degradation of service.

IP Options

This category provides the IP address configuration required in the case of non-PPP routed connections.

Available choices are: automatic configuration through

DHCP

, and

Static IP

address configuration. In

the latter case:

Gennet s.a.

63

OxyGEN

mini

Office

Administrator’s Guide

1.

IP Address

is the IP address used for the WAN interface.

2.

Netmask

is the corresponding subnet mask.

3.

Gateway

is the default gateway, used only if the

Default route

option described below is either

Yes

or

Backup

.

IP Routing

The

Default route

parameter defines if the connection will provide the default route for Internet

connectivity.

Available options are

Yes

, for a connection offering default route,

Backup

, for a

connection acting as a backup in case of failure of the default-route connection, and

No

, for any plain

connection without a default-route gateway.

Note

Only one connection is allowed to provide default route. Usually, this connection will be

the one providing Internet Data service.

DSL Line

In this configuration sub-menu, it is possible to modify the different parameters controlling the functionality

of the DSL modem embedded into the OxyGEN

mini

Office.

Figure 6.8: DSL Line Parameters

The following parameters can be configured:

Bitswap

: swap bits around different frequency channels, in order to adapt to changes of the line

conditions without retraining.

SRA

: seamless rate adaptation of the DSL data rate as a response to changes of the line conditions

in order to avoid dropping a connection.

Annex M

: a variation of the ADSL technology offering increased upload speed

(if supported by

your model of the OxyGEN miniOffice and by the ISP’s DSLAM - PSTN connections only)

.

Databoost

: a special, proprietary, mode of operation offering higher speeds of connection

(if

supported by the ISP’s DSLAM)

.

EC/FDM Mode

: choice between

echo-cancellation

(EC) or

frequency division multiplexing

(FDM)

mode of operation.

Coding Gain

: the increase in efficiency that the coded signal provides over an uncoded one.
