4 Managing CPE Devices

The WiMAX CPE product supports three main management interfaces: TELNET, WEB and TR-069

management from local or from remote central offices.

AirStream 4000/4001 WiMAX CPE User Manual

User name and password are required for access to management functions. There are two levels or privileges:

administrators’ privilege and normal users’ privileges.

 Administrator’s privilege is designed for service providers to provision a CPE device before selling or

leasing out to end users. By supplying administrator’s user name and password, a technician has access

to all configurations of a CPE device. Default user name for administrator’s privileges is “admin”.

Default password is “admin”.

 Users’ privilege is provisioned for end users to make limited changes of configurations for a CPE

device. Most of other configurations are not visible when accessed with normal user’s privileges.

Default user name and password for user is “user”.

4.1 Managing CPE via Telnet Access

To Telnet into CPE device, the IP address of its WAN interface or LAN interface must be known:

 Default IP address for the LAN interface is 192.168.0.1, unless the configuration has been modified.

 The IP address for WAN interface is usually acquired from service provider’s network after CPE

connects to the WiMAX network.

4.1.1 Telnet Access to CPE from LAN Segment

The user may Telnet into the CPE by specifying the IP address of CPE LAN interface. The default IP Address of

the CPE LAN interface is 192.168.0.1.

The CPE acts as a DHCP server for hosts in LAN segment by default, unless this feature is disabled. Control

Station may dynamically acquires an IP address from CPE built-in DHCP server.

After IP connectivity is established between the Control Station and CPE, the user may Telnet into the CPE.

4.1.2 Telnet Access from Wireless Interface Segment

The user may also Telnet into the CPE by specifying the wireless IP address of the CPE device. Access from

Wireless interface is very helpful for remote troubleshooting.

The wireless IP address is usually acquired via DHCP once the CPE is connected into the service provider’s

network. To find out the wireless IP, Support technician may seek end user’s help to find out IP address of the

wireless interface of CPE located in customer premise. The easiest way for end users is to follow the

instructions outlined in Section 4.2.1. End users may be given a user name and password with lower privilege to

access limited information stored in the CPE.

CAUTION Telnet from remote location is not recommended as user name and password are

sent in clear text. Malicious users may sniff IP packets and find administrator’s

credentials easily.

4.2 Managing CPE via Web Browser

It is a preferred way to manage the CPE using a Web browser from a local or remote host, for example, Internet

Explorer in Windows operation systems.

The reader has the option to access the CPE using the LAN interface or wireless IP if it is known.

 The default IP address for the LAN interface is 192.168.0.1, unless the configuration has been modified.

 The WAN IP is usually acquired from service provider’s network after CPE connects to the network.

4.2.1 Access CPE from LAN Interface

Connect the LAN port of Control Station (a PC) directly to the LAN port of the CPE, or in-indirectly via an

Ethernet hub or switch. By default, the CPE will act as a DHCP server for hosts in the LAN segment unless this

feature is disabled. The Control Station can dynamically acquire an IP address from CPE’s built-in DHCP server.

After IP layer connectivity is established between the Control Station and the CPE, the user may launch a Web

browser and specify http://192.168.0.1 in the address bar. A window will pop up requesting user name and

AirStream 4000/4001 WiMAX CPE User Manual

password. If the device WiMAX WAN IP assigned is within the same subnet as the LAN IP, the LAN IP by

default will be automatically switched to 10.10.0.1.

Input user name and password, and then click on the “OK” button. After a successful log on, the welcome page

of web management interface will appear.

Figure 2. Logon Web Page

4.2.2 Access CPE Device from WAN Segment

Service providers may access the CPE Web management interface remotely, by specifying the CPE wireless IP

address obtained after connecting to the service provider network.

As the wireless IP address is dynamically assigned by the service provider, the support technician may seek end

user’s help to find out the IP address of wireless interface for the CPE located in customer premise. The end user

can retrieve the wireless IP by following the instructions outlined in Section 4.2.1.

 Identify or Network Address Identified (NAI)

 Inner Identity or User Name

 Password

6.5 Advanced Setting

Use the advanced setting to select IOT Mode and configure MS Capability and Network Access options.

IOT Mode can be enabled with a selection of more than 17 popular base station types. The “Unified” mode is

the default mode for IOT with many BS vendors.

The advanced setting also allow user to configure MS Capability and Network Access settings including auto

idle support, auto connect, and roaming and etc.

The MS by default supports IDLE, HANDOVER and IDLE. Depending on the BS type, these may need to be

disabled for better interoperability. For BS that support IDLE and SLEEP operation, the CPE should enable the

auto-idle and auto-sleep feature.

For Network Access settings, it is intended for service provider configuration. The auto-connect should be

always enabled to allow seamless user connection. Enable Roaming option to obtain the service roaming

capability. The rest of setting should be configured by the service operator and user should not alter them.

AirStream 4000/4001 WiMAX CPE User Manual

7 Network Configurations

This section discusses the configuration to establish connectivity between a CPE and wireless network. When

clicking on the Network Configuration link, the following menu will be displayed.

7.1 WAN Networking

Click on “WAN Networking” in the Configuration tree. The web page in the detailed configuration frame will

show WAN IP Address Setting and DNS Configuration. For WiMAX access, dynamic IP should be enabled for

WAN interface.

7.1.1 WAN IP Address Setting

The interfaces can be shut down or brought up at electrical level. When the interface is up, the interface can be

enabled or disabled at logical level. The interfaces may acquire an IP address dynamically, or be given a static IP

address.

7.1.2 DNS Configuration

When wan interface acquires an IP address from the network, it is likely that information of DNS servers is

provided by the DHCP servers in the network. Manual setting is not necessary. But it is also possible to

manually specify DNS server address in the table above.

Note NAT must be enabled if DHCP server is enabled. DHCP server is

enabled by default.

AirStream 4000/4001 WiMAX CPE User Manual

7.2 LAN Networking

An operation mode of Router or Bridge can be selected via Web management.

When choosing Router mode, you can also enable or disable DHCP Server, and configure LAN and DHCP

Server IP.

By default this DHCP server feature is enabled for LAN segment. A default IP address pool is allocated by the

CPE. It is not recommended to change this setting in general. If readers do wish to specify an IP pool manually,

please be reminded that the Gateway for LAN segment should be the IP address of CPE’s LAN interface.

Notice The Gateway for LAN segment is usually the LAN interface of the CPE. If the

IP pool for DHCP server is modified to other subnets, e.g. 192.168.1.0/24, the

Gateway and IP address for the CPE LAN interface should be modified

accordingly.

7.3 QoS & VLAN

The CPE data traffic are classified into three types and each can be marked with certain QoS priorities, at layer

two or layer three of the seven-layer OSI network model. At layer 2, 802.1p bits are used for QoS Marking. At

layer 3, the DSCP field in IP header is used for QoS marking as shown by the following diagram. Note that

DSCP and TOS marking cannot be configured at same time.

VLAN (Virtual Local Area Network) allows separation of traffic by a VLAN ID at layer two of the seven-layer

OSI network model. VLAN may facilitate implementation of security measures, and QoS treatment. The CPE

internally classifies traffic into three types, Voice (media and signaling), Data and Management traffic. The

traffic types can be tagged with designated VLAN ID. All ingress traffics from LAN port are treated as data.

VLAN tagging for CPE LAN traffic can be enabled or disabled. VLAN IDs for Voice, Data and CPE

Management traffic can be configured in this section. For the LAN port data, untagged LAN traffic will be

automatically tagged at the WAN interface according to the traffic type.

AirStream 4000/4001 WiMAX CPE User Manual

7.4 VPN Networking

To enable VPN networking for enterprise user, the CPE has integrated L2TP client function within the device.

To use the L2TP function, the user needs to enable and configure the L2TP client as the following. Once the

L2TP connection is established, all data from the LAN port will be forwarded to the L2TP server for processing.

AirStream 4000/4001 WiMAX CPE User Manual

7.5 Access Control

User can enable and setup MAC Filer to prevent computers with specified MAC address from accessing to CPE.

The operator can also configure the User Access Control to limit the device usage by the user. The Max User

Allowed, Highest Port Number Allowed and Minimum Inactive Timeout can be configured to restrict the LAN

device access.

8 Firewall Configuration

Click “Firewall configuration” on the left configuration tree. And then you have the access to Virtual Server and

IP Filtering Rules.

8.1 Virtual Server

Virtual Server function allows user to expose internal server to the Internet. The following configuration

can be used to expose certain server IP and port number to Internet and support DMZ functions. Three

traffic types (UDP, TCP, TCP&UDP) traffic types can also be specifed for virtual server mapping.

8.2 IP Filtering Rules

IP Filter capability provides user the filter out unwanted traffic for security management. Either black or white

rule can be specified for non-matching data traffic. The filtering rule can be created based protocol type, source

and destination IP and port ranges.

Note the IP filtering has a performance impact on the CPE processing capability. Therefore use is advised to

9 VoIP Configurations

9.1 SIP Configuration

SIP related configurations concern CPE as a SIP client, Registrar and Proxy Servers.

Click on “SIP Configuration” in the Configuration Tree to access the related web management page.

9.1.1 User Configuration

Internally FXS ports are counted from 0. Phone line 1 maps to FXS Port No 0. “User ID” maps to dial number.

Apply settings if changes are made in the above section.

Next comes to Registrar configurations.

When “Enable Register” is enabled, registration message will be sent out. However when “Use Proxy as

Registrar” is enabled, all registration message is sent to the IP address of the Proxy. When “Enable Register” is

disabled, the IX253P CPE may be configured for point to point communications, which is typically used by an

enterprise owning multiple office sites. Apply settings if changes are made in the above section.

AirStream 4000/4001 WiMAX CPE User Manual

Proxy can be enabled and configured. And if more than one Proxy Addresses are supplied, the CPE will try each

Proxy sequentially if a request to a Proxy times out with no responses. Apply settings if changes are made in the

above section.

After completing all settings, you may uncheck “Enable Register” and apply settings to de-register the FXS port.

Check “Enable Register” and apply settings again to perform another registration. If a registration is successful,

“Port Status” under “User Configurations” should show “Register Success”.

SIP Protocol parameters, such as Hook Flash, Max Forwards and Max Auth can be configured.

For service provider networks, the SIP control protocol is the mainstream protocol selected by the

telecommunication standardization bodies. For example, 3GPP and 3GPP2 have adopted SIP as the foundation

for future communication networks.

The CPE need not be reset if changes are made at application level, e.g. Proxy IP address change. However the

media protocol can be restarted to effect changes.

Different VoIP network equipment vendors may have implemented SIP protocol in different ways. Table below

summarizes the use of configuration values in various SIP messages.

In SIP standards, the “User ID” could be a mix of alphabetic and numeric digits. However, in a network with

analogue phones, “User ID” is recommended to use numeric digits only as the CPE takes user inputs from

phone pad to construct “User ID” of the called party.

The “User ID” field should consist of numeric digits only.

9.2 Number Analysis Configuration

The CPE collects dial numbers from external phone or fax. Dialed digits are analyzed before being sent out to

other element in a VoIP network. Dial numbers can be modified according to specific needs. Rules can be setup

to modify a dial number, if it meets certain condition.

Click on “Number Analysis Configuration” in the Configuration Tree. Conditions and associated actions on dial

numbers are displayed in the detailed configuration window.

The conditions are defined in Call Route Configuration section. The actions are defined in Number Change

Configuration section.

9.2.1 Conditions to Modified Dial Numbers

The Current Call Route List table shows conditions that triggers certain action on a dialed number string.

AirStream 4000/4001 WiMAX CPE User Manual

 “Number Prefix”, “Min Length of Number”, and “Max Length of Number” are used in combination to

define a condition.

 “Route Address” may specify another SIP capable node to route a call. If this field is left empty,

configuration in User Agents setup applies. This feature was widely used for point to point calls

without involvement of Proxy servers, in early years of VoIP network evolution.

 “Change Index” specifies the index of an action in “Current Change List” table to be taken, if a dial

number matches with the condition.

Example in the table shows that dial numbers starting with 021, is subject to the change defined in action 0

defined in the Current Change List.

9.2.2 Number Change Configurations

The “Number Change Configuration” section defines the actions to be taken, if a dial number meets certain

conditions defined in “Call Route Section”.

 “Index” defines the index of action.

 “Type” defines type of changes. Certain digits can be inserted into a dialed number. Digits in a dial

number can also be modified or deleted.

In the example, the change action, defined by entry with “Index” 0 in the “Current Change List”, inserts “8541

from the 3rd position of the number string.

AirStream 4000/4001 WiMAX CPE User Manual

So a dial number 0212401 is modified to 021 8541 2401 before the CPE device sends out a call invite.

9.3 Call Configuration

Call Configuration section defined a few behavior when a call is outgoing or incoming. Click on “Call

Configuration” in the Configuration Tree. The following sections will be displayed in the detailed configuration

window:

9.3.1 Dial Plan Configuration

The CPE collects dial numbers from external phone or fax. Dialed digits are collected as a whole before they are

encapsulated in a call Invite message.

By default the CPE takes five second idle time after the last punch, as completion of user input. Digit mapping

are introduced to allow faster recognition of dial completion. If the dialed digits, input by user from the phone

pad, map with any pattern of DigitMaps defined in this section, collected digits are immediately processed.

Maximum 500 digit maps can be defined. Each digit map may consist up to 2048 characters. In the “Dial Plan

(DigitMap) Configuration” textbox, each digitmap are separated by an “|” character. The string

“XX.T|XX.#|P|****” consists of four digit maps:

 “*XX” means an asterisk followed by 2 digit of any number. Dial strings matching this pattern are used

for service codes, which allows user interaction by end users, e.g disable or enable call forwarding.

Refer to 9.5.1 for more detailed information.

 In “XX.T”, “XX” means any digits. “.” means any number of digits. T means a timer. The entire string

means CPE wait for T seconds after the last user punch on phone pad.

 In “XX.#”, “XX” means any digits. “.” means any number of digits. The entire string means dialed

digits can be processed by press “#” button. Whenever CPE receives an “#”, CPE considers that user

inputs has completed, and start processing digits before “#” immediately.

 The last digit map “****” is defined for use by CPE itself. When user press “****”, the IP address of

the CPE is announced in the ear set of the phone.

When IP Dialing is enabled, the CPE also allows call origination to an IP address input by user from key pads of

a phone.

For example, call to 1000@10.3.50.55:5060 can be dialed by pressing the following numbers:

1000**10*3*50*55**5060.

9.3.2 Multiple Lines using a Single Account

Multiple phones may share one SIP address, or account. Port number 0-3 may use exactly the same “User ID”,

“Auth Username”, etc. Phones connected to any port can make outgoing calls.

In this scenario, if there is an incoming call to the “User ID”, which local phone should ring? This is defined in

“Call Parameter Configuration” in this section.

AirStream 4000/4001 WiMAX CPE User Manual

A few options are available in the drop down list of Port Select Mode in Group:

 Early Release First: the line which was released earliest receives an incoming call.

 Random: an incoming call is randomly dispatched to one of the lines.

 Order: an incoming call is dispatched to lines sequentially.

9.3.3 Call Timers

A few timers are defined in this section:

 Ringback Timer: A ringback tone, or audible ringing tone or ringback signal, is the audible ringing that

is heard on the telephone line by the calling party after dialing and prior to the call being answered at

the distant end. When A calls B from a CPE, if B does not answer the call, the “Ringback Timer”

defines the maximum waiting time after which the CPE should tear down the call, (if A does not hang

up the phone).

 Ring Timer: A ring tone is the sound made by a telephone to indicate an incoming call. When B calls A

at a CPE, if A does not answer the call, the “Ring Timer” defines the maximum waiting time after

which the CPE should tear down the call, (if B does not hang up the phone).

 Busy Timer: when A calls B, if B is busy, the “Busy Time” defines the maximum waiting time that the

CPE should tear down the call, (if A does not hang up the phone).

 Offhook Warning Time: The maximum waiting time after which the CPE should send warning signals

to the line.

9.4 DSP Configuration

Voice is sampled and coded into digital bit stream, before they are packetized into IP packets. The following

sections discuss various Codecs supported by the CPE

The parameters are explained in more details:

 DTMF Transfer Mode: DMTF stands for Dual-Tone Multi-Frequency (DTMF) signaling, which is used

for transfer of telecommunication signal over the line in the voice-frequency band in legacy PSTN

networks. In VoIP networks, legacy devices continues to use DMTF to send busy signal, Flash or

alphanumerical digits. For example, a user may be required to key in a password to join a conference

call, which is sent from legacy phone as DTMF signal, across the IX253P CPE, to the conference

bridge. There are a few ways to transport DMTF tones from legacy devices, over a VoIP network.

o Audio Stream: DTMF signals from legacy phones are packetized in RTP packets as audio

stream. Transporting DTMF user inputs as audio stream works well in a data network with

AirStream 4000/4001 WiMAX CPE User Manual

good quality. However, in networks with poor quality, packet losses or disordered delivery of

RTP packet may cause error. An alphanumerical digit input by the caller may be interpreted

wrongly as another digit.

o RFC2833: As a second option, the CPE can recognize the tones and translate them into a

name, such as numeric input, or Flash. RFC2833 defined payload format for named telephone

events, such as numeric input, or Flash.

o Signal: means the DTMF tones are translated to application level parameters such as SIP.

 Echo Cancellation: can be turned ON or OFF.

 Silence Suppression: can be turned ON or OFF.

 DSP Gain: Default value is 0. It may be adjusted to increase or decrease voice volume.

 Supported Codec: IX253P CPE supports automatic negotiation of codec with the network. The

Supported codecs, namely PCMa, PCMu, G.726, G.723, and G.729, are announced to the called party in

SIP Invite messages.

 Preferred Codec: Preferred Codec should be chosen in line with service provider’s strategy.

 Packetization Period: The period that a voice bit stream is packetized into an IP packet. The shorter the

period, the less delay of voice. Typical values are 5, 10, 20 milliseconds.

 G723 Rate: G723 supports two encoding data rate. This option allows the choices of encoding rate

using G.723 encoders.

 RFC2833 Payload: The payload value to send DMTF tones according to RFC2833.

 FSK Type: Frequency-shift keying (FSK) is a form of frequency modulation in which the modulating

signal shifts the output frequency between predetermined values. DTMF is one of the FSK applications.

It supports BellCore, ETSI, NTT options.

AirStream 4000/4001 WiMAX CPE User Manual

Information G.723 and G.729 cannot be enabled at same time. PCMu or PCMa Law can be

chosen in Line Configurations. Only one codec can be used at a time.

Most legacy fax devices adopt ITU-T Group 3 fax protocol published in 1990. The protocol is composed of

server standards that specify different parts the fax call. Amongst them T.30 specification defined procedure to

set up a fax call, determine the image size, encoding, transfer speed, the demarcation between pages, and the

termination of the call. T.30 also references the various modem standards for handshaking (V.21 Channel 2

Model at 300mbps), and for image transfer (V.27 Ter, V.29, V.17, and subsequently V.34).

The simplest approach to transfer fax over an IP network is the bypass mode. CPE or other gateway devices

simply samples all transmissions from fax machine using PCM (Pulse-code modulation) at 64kbps, and

transports the bit string to the other gateway at edge of the network.

Figure 4. Transfer of T.30 Faxes in Transparent Mode

Transparent transfer provides no protection to packet loss, and requires big buffer in the in the gateway device to

combat network delay jitter. Tolerance of round trip delay for the IP network is a stringent 2 seconds. Delay

longer than that will cause failure of fax transmission.

More reliable and preferred method of delivery fax via an IP network is fax relay. The T.38 fax relay standard

was devised in 1998 as a way to permit faxes to be transported across IP networks between existing G3 fax

terminals.

Figure 5. Transfer of T.30 Faxes using T.38 Fax Relay

AirStream 4000/4001 WiMAX CPE User Manual

The configurations are explained in more details:

 Fax Mode: Transparent or T.38. The later is more preferred.

 Rate Management: Local TCF, and Transferred TCF. At this moment only Transferred TCF is

supported.

 UDP Error Correction: Redundancy or FEC. At this moment, only Redundancy is supported.

Redundancy method means payload transmitted in previous IP packet is repeated in a later packet.

 Max Buffer: (100~65535)

 Max Datagram: (50~65535)

 Max Rate: 2400bps, 4800bps, 7200bps, 9600bps, 12000bps, 14400bps.

 Port Offset: (0~9)

 Send NAT T38: No or Yes. If an external session boarder gateway is implemented in the network,

choose No.

9.5 Enhanced Services

The CPE supports a rich set of supplementary services. Click on “Enhanced Services”, the following

Supplementary Service Subscription are displayed in the right frame of browser window:

The CPE provide three level of control to supplementary services:

 Is the service enabled? Typically this is controlled by the service provider.

 Is the service activated? Typically this is controlled by end user, e.g. he may activate “call forwarding

no answer” before he leaves his desk and goes home. Users may dial services codes to activate or

activate these features.

 What parameter should be used for certain feature, e.g. which number to forward a call? This is

AirStream 4000/4001 WiMAX CPE User Manual

specified by user by dialing the service codes, e.g. *90075533639088 specifies that incoming calls

should be forwarded to 075533639088.

9.5.1 Service Codes Configuration

Many of the enhanced services need to be provisioned with the proper activation codes to work with the soft

switch. The default service codes are displayed below. Service codes are configurable.

The Conference ID filed is used to set the corresponding network conference server name used in the network

3WC calling service (Applicable to Sonus Switch Only).

9.5.2 Use of Enhanced Services

The enhanced services are divided into local CPE terminal services and network services. Except Blind Call

Transfer, Call Park and Call Pickup service codes are network based service activation codes, all other service

codes are local CPE specific service codes. They are used by the user to activate or deactivate IAD local

services via telephone dialing.

The CPE allows user to use a combination of flash hook and service codes dialing to access the enhanced

services. The following combinations of operation are commonly used for user service operation.

Flash hook + press 1 – terminate the current call and connect to the held or new pending call.

Flash hook + press 2 – hold the current call and connect to the held call or new pending call.

Flash hook + press 3 – conference two calls that are being connected or held.

Some typical uses of the enhanced services are briefly described in the following as examples:

AirStream 4000/4001 WiMAX CPE User Manual

Call waiting:

For the second incoming call, the user has the following two options to take the new incoming call:

■ Option 1 - flash hook and press 1, the old call will be dropped and the new call will be connected.

■ Option 2 - flash hook and press 2, the old call will be hold and the new call will be connected. Flash

hook and press 2 again will switch the connection to the previous call.

Call Transfer:

After receiving the call from the first party, user can flash the hook and dial the second party. After the

second party answers the call, user has the following option to proceed:

■ Option 1 - hang up the phone and transfer the first call to the second party.

■ Option 2 - flash hook and press 1, the second party will be dropped and the first party will be

connected.

■ Option 3 - flash hook and press 2, the second party will be on hold and the first party will be

connected. Flashing hook and press 2 again will switch the connection to the second party and etc.

Local and Net 3WC:

After establishing the two calls (one on hold and one connected), the user can conference three parties by

flashing the hook and press 3. Of course, instead of conferencing, the user still has the option to switch

calls by flash hook and press 1or 2.

Blind Transfer:

After receiving the call from the first party, the user dials the blind call transfer service codes (e.g. *68) and

the second party number to transfer the call to second party. The user then hangs up the phone.

Call Park/Call Pickup:

After receiving an incoming, the user flashes hook and dials the call park service code (e.g. *98) + another

party number, the call will be parked for the second party in the network.

Another user can pickup the parked call by dialing the Call Pickup Service code of the call from the first

party, and the user dials the blind call transfer service code (e.g. *99) and the second party number to

retrieve the call.

If a parked call is not picked up within certain time, the call will be discarded by the system.

9.6 Line Features

User Settings specify user specific parameters for supplementary services. These settings will remain even their

associated features are deactivated, so that users are not required to set them next time.

Hotline refers to automatic dialing out to a pre-determined number, if a user takes a phone off hook but dials

AirStream 4000/4001 WiMAX CPE User Manual

nothing. Hotline is configured on per FXS port basis.

For each port, you are allowed to set the Whitelist and Blacklist. Blacklist gives the numbers which you are not

allowed to call, and Whitelist gives you the only numbers you are allowed to call. Type in the number in the

blank area directly, and a symbol “|” is used between two numbers.

9.7 Port Configuration

Port configuration defines physical and electrical layer parameters, such as port transmit power.

Click on “Port Configuration” in the Configuration menu to access management web page for port

configurations.

9.7.1 Port Attribute

Most of the configurations are self explaining in the port attribute section.

AirStream 4000/4001 WiMAX CPE User Manual

On Port Gain settings, the value before “/” is for transmission, the one after “/” is for receiving. The min and

max hook times are relevant to the detection of a flash. If the phone is put on and off hook quickly and the

duration is between min and max hook time, the operation is considered the same as pressing the Flash button.

9.7.2 Port Application Attribute

The CPE allows controlling fax function by each port. Configuration page is as follows:

9.7.3 Private Number

Private numbers were used for point to point VoIP call setups without the involvement of Proxy server. This is

not required for a service provider’s network where VoIP core network infrastructure is implemented.

In the scenario with no proxy servers and registrar, dial numbers must be planned carefully. Let us use an

example to elaborate this scenario.

9.7.4 Line Maintenance

The CPE may block some ports temporarily. This option maintains the user agent setting.

AirStream 4000/4001 WiMAX CPE User Manual

9.8 STUN Configuration

STUN (Simple Traversal of User Datagram Protocol (UDP) Through Network Address Translators (NATs)) is a

network protocol allowing clients behind NAT (or multiple NATs) to find out its public address, the type of NAT

it is behind and the internet side port associated by the NAT with a particular local port. This information is used

to set up UDP communication between two hosts that are both behind NAT routers.

Protocols like SIP use UDP packets for the transfer of sound and/or video and/or real-time text signaling traffic

over the Internet. Unfortunately as both endpoints are often behind NAT, a connection cannot be set up in the

traditional way. This is where STUN is useful.

STUN is a client-server protocol. A VoIP phone or software package may include a STUN client, which will

send a request to a STUN server. The server then reports back to the STUN client what the public IP address of

the NAT router is, and what port was opened by the NAT to allow incoming traffic back in to the network.

By default, a STUN server in the public domain larry.gloo.net has been configured as the secondary server. The

Service Provider may specify address of its own STUN server, if implemented, as a primary server.

The response also allows the STUN client to determine what type of NAT is in use, as different types of NATs

handle incoming UDP packets differently. There are four main types of NAT:

 full cone NAT,

 restricted cone NAT, and

 port restricted cone NAT.

 symmetric NAT (also known as bi-directional NAT)

The CPE has built in intelligence to work with three of four main types: full cone NAT, restricted cone NAT, and

port restricted cone NAT, by pre-adjust the outgoing SIP messages and voice using public IP address and source

port discovered.

The CPE will not work with symmetric NAT (also known as bi-directional NAT).

11.2 Load and Backup

This section demonstrates “Load” and “Backup” transaction via a web management interface. Let us start with

discussion of a few terminologies:

Program refers to the file which contains binary instruction sets that controls the CPE

system.

Data refers to the file which contains network and user specific configuration

Load refers to transferring of system program file or configuration data file from an

external host into a CPE.

Backup means saving of configuration data file from a CPE to an external host.

TFTP and HTTP protocols are supported to Load and Backup new firmware and/or system configuration files.

Configuration data can be backed up from CPE to an external host, or restored from external computer into a

CPE IAD. The external host must have IP connectivity with the CPE device.

11.2.1 Load or Backup over HTTP

Similarly, the system firmware and configuration files can be loaded into the CPE via HTTP protocol. The

configuration files can be backed from the CPE to the external host. The external host in this case is the

computer which runs the web browser to access the network management pages.

Information The external host in this case serves as a HTTP client. The CPE serves as a

HTTP server.

11.2.1.1 Load System Files to an CPE from a Web Browser
