PARAMETER

DEFINITION

Band

You can select 2.4GHz or 5GHz.

Channel

Fill in the appropriate channel to correspond with your network settings. All devices in your wireless network must use the

same channel in order to work correctly. This router supports auto channeling functionality.

Auto Channel Timer(min)

Specifies the timer of auto channelling.

802.11n/EWC

Select disable 802.11n or Auto.

Bandwidth

Select the bandwidth for the network. You can select 20MHz in Both Bands, 20MHz in 2.4G Band and 40MHz in 5G Band,

or 40MHz in Both Bands.

Control Sideband

If you select 20MHz in Both Bands or 20MHz in 2.4G Band and 40MHz in 5G Band, the service of control sideband does not

work. When you select 40MHz in Both Bands as the bandwidth, the following page appears. Then you can select Lower or

Upper as the value of sideband. As the control sideband, when you select Lower, the channel is 1~7. When you select

Upper, the channel is 5~11.

802.11n Rate

Select the transmission rate for the network. The rate of data transmission should be set depending on the speed of your

wireless network. You can select from a range of transmission speeds, or you can select Auto to have the Router

automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best

possible connection speed between the Router and a wireless client. The default value is Auto.

802.11n Protection

The 802.11n standards provide a protection method so 802.11b/g and 802.11n devices can co-exist in the same network

without “speaking” at the same time.

Support 802.11n Client Only

Only stations that are configured in 802.11n mode can associate.

Multicast Rate

Select the multicast transmission rate for the network. The rate of data transmission should be set depending on the speed of

your wireless network. You can select from a range of transmission speeds, or you can select Auto to have the Router

automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best

possible connection speed between the Router and a wireless client. The default value is Auto.

Basic Rate

Select the basic transmission rate ability for the AP.

Fragmentation Threshold

Packets that are larger than this threshold are fragmented into multiple packets. Try to increase the fragmentation threshold if

you encounter high packet error rates. Do not set the threshold too low, since this can result in reduced networking

performance.

RTS Threshold

This value should remain at its default setting of 2347.Should you encounter inconsistent data flow, only minor reductions are

recommended. Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is

recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be

enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a

data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right

to begin transmission. The RTS Threshold value should remain at its default value of 2347.

DTIM Interval

(Delivery Traffic Indication Message) Enter a value between 1 and 255 for the Delivery Traffic Indication Message (DTIM.) A

DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages.

Beacon Interval

A beacon is a packet of information that is sent from a connected device to all other devices where it announces its availability

and readiness. A beacon interval is a period of time (sent with the beacon) before sending the beacon again. The beacon

interval may be adjusted in milliseconds (ms).

Default (100) is recommended.

XPress Technology

Select Enable or Disable. This is a special accelerating

technology for IEEE802.11g. The defaule is Disabled.

Transmit Power

Adjust the transmission range here. This tool can be helpful for security purposes if you wish to limit the transmission range.

WMM (Wi-Fi Multimedia)

Select whether WMM is enable or disabled. Before you disable WMM, you should understand that all QoS queues or traffic

classes relate to wireless do not take effects.

WMM No

Acknowledgement

Select whether ACK in WMM packet. By default, the 'Ack Policy' for each access category is set to Disable, meaning that an

acknowledge packet is returned for every packet received. This provides a more reliable transmission but increases traffic

load, which decreases performance. To disable the acknowledgement can be useful for Voice, for example, where speed of

transmission is important and packet loss is tolerable to a certain degree.

WMM APSD

APSD is short for automatic power save delivery, Selecting enable will make it has very low power consumption. WMM Power

Save is an improvement to the 802.11e amendment adding advanced power management functionality to WMM.

Voice

This section explains how to configure the VoIP settings of the NF4V.

VoIP Status

The Voice Status page displays the registration status of your SIP accounts and the total call time of each account.

SIP Basic Setting

The SIP Settings page is where you enter your VOIP service settings as supplied by your VOIP service provider (VSP). If you are

unsure about a specific setting or have not been supplied information for a particular field, please contact your VOIP service

provider to verify if this setting is needed or not.

The individual fields shown above on the SIP Basic Settings page are explained in the following table.

OPTION

DEFINITION

Bound Interface Name

Select the Interface that the VoIP account will use to make a connection to the VoIP Service Provider.

SIP Local Port

Set the SIP local port of the gateway, the default value is 5060. SIP local port is the SIP UA (user agent) port.

SIP domain name

Enter the SIP domain name or IP address of your VoIP Service Provider here.

Use SIP Proxy

Select the checkbox of Use SIP Proxy, if your DSL router uses a SIP proxy. SIP proxy allows other parties to

call DSL router through it. When it is selected, the following fields appear.

SIP Proxy

The IP address of the proxy.

SIP Proxy port

The port that this proxy is listening on. By default, the port value is 5060.

Use SIP Outbound Proxy

Some network service providers require the use of an outbound proxy. This is an additional proxy, through

which all outgoing calls are directed. In some cases, the outbound proxy is placed alongside the firewall and it

is the only way to let SIP traffic pass from the internal network to the Internet. When it is selected, the following

fields appear.

SIP Outbound Proxy

The IP address of the outbound proxy.

SIP Outbound Proxy port

The port that the outbound proxy is listening on. By default, the port value is 5060.

Use SIP Registrar

Select this option if required by your VoIP Service Provider. Enter the SIP Proxy Domain Name and SIP Proxy

Port which is typically 5060.

SIP Registrar

The IP address of the SIP registrar.

SIP Registrar port

The port that SIP registrar is listening on. By default, the port value is 5060.

Account Enabled

If it is unselected, the corresponding account is disabled. You can not use it to initiate or accept any call.

Polarity Reverse Enable

Enable or disable this function.

Authentication name

Set the user name of authentication.

Password

Set the password of authentication.

Cid Name

User name. It is the Display Name.

Cid Number

Set the caller number. It must be a number of 0~9.

ptime

You can use it to set the packetization time (PT). The PT is the length of the digital voice segment that each

packet holds. The default is 20 millisecond packets. If selecting 10 millisecond, packets improve the voice

quality. Because of the packet loss, less information is lost, but more loads on the network traffic.

Priority

The priority of codec is declined from up to down. Codecs define the method of relaying voice data. Different

codecs have different characteristics, such as data compression and voice quality. For Example, G723 is a

codec that uses compression, therefore, it is good for use where the bandwidth is limited but its voice quality is

not good as other codecs, such as the G711. If you specify none of the codecs, using the default value

showed in the above figure, the DSL router chooses the codec automatically.

After entering your VoIP settings press the Apply button. Select Management > Save/Reboot and press the Reboot button. Once

the router restarts if there is a valid internet connection and the VoIP account settings are valid the VoIP service will start.
