Table 11 - Data connection item details
Connecting to the mobile broadband network
The router supports the configuration of up to six APN profiles; these profiles allow you to configure the settings that the router will
use to connect to the broadband network and switch easily between different connection settings.
Manually configuring a connection profile
To manually configure a connection profile:
1. Click the Edit button corresponding to the Profile that you wish to modify. The data connection profile settings page is
displayed.
Figure 15 - Data connection profile settings
www.netcommwireless.com
NetComm Wireless 4G WiFi M2M Router
21
UM-00009
2. Click the Profile toggle key to turn the profile on. Additional settings appear.
Figure 16 - Data connection settings - Profile turned on
3. In the Profile name field, enter a name for the profile. This name is only used to identify the profile on the router.
4. Ensure that the Automatic APN selection toggle key is set to off. If it is not, click it to toggle it to the off position.
5. In the APN field, enter the APN Name (Access Point Name) and if required, use the Username and Password fields to
enter your login credentials.
6. Next to Authentication type, select either CHAP or PAP depending on the type of authentication used by your provider.
7. The Reconnect delay field specifies the number of seconds to wait between connection attempts. The default setting of 30
seconds is sufficient in most cases but you may modify it to wait up to 65535 seconds if you wish.
8. The Reconnect retries field specifies the number of times to attempt a network connection if the router fails to establish a
connection. It is set to 0 by default which causes the router to attempt to reconnect indefinitely.
9. The Metric value is used by router to prioritise routes (if multiple are available) and is set to 20 by default. This value is
sufficient in most cases but you may modify it if you are aware of the effect your changes will have on the service.
10. The MTU field allows you to modify the Maximum Transmission Unit used on the connection. Do not change this unless
instructed to by your carrier.
11. Use the NAT Masquerading toggle key to turn NAT Masquerading on or off. NAT masquerading, also known simply as
NAT is a common routing feature which allows multiple LAN devices to appear as a single WAN IP via network address
translation. In this mode, the router modifies network traffic sent and received to inform remote computers on the internet
that packets originating from a machine behind the router actually originated from the WAN IP address of the router’s
internal NAT IP address. This may be disabled if a framed route configuration is required and local devices require WAN IP
addresses.
12. Click the Save button when you have finished entering the profile details.

Connect on demand
The Connect on demand feature keeps the Packet Data Protocol (PDP) context deactivated by default while making it appear to
locally connected devices that the router has a permanent connection to the mobile broadband network. When a packet of interest
arrives or an SMS wake-up command is received, the router attempts to establish a mobile broadband data connection. When the
data connection is established, the router monitors traffic and terminates the link when it is idle.
Note: When interesting packets arrive, the recovery time for the wireless WAN connection is approximately 20-30 seconds.
Configuring Connect on demand
To configure Connect on demand:
1. Click the Networking menu item from the top menu bar.
2. On the Connect on demand page, click the Connect on demand toggle key so that it is ON. Extra options appear. See the
following sub-sections for further instructions.

Setting the router to dial a connection when traffic is detected on specific ports
In some situations, you may wish to have the internet connection disabled except at times when outbound traffic to a particular
external host’s port or group of ports is sent to the router. To use this feature, click Enable dial port filter and enter the port number
or list of port numbers separated by commas. When you select this option, all outbound ICMP/TCP/UDP packets to any remote
host on the specified port(s) will trigger the connection to dial. Note that when this feature is enabled, the options to ignore specific
packet types are not available.
Figure 21 – Connect on demand - Data activity triggered connection
You can allow Microsoft network awareness (NCSI) traffic through but if you prefer that they do not trigger the connection, click the
Ignore Microsoft network awareness (NCSI) traffic toggle key to set it to ON.
Figure 22 - Connect on demand - Ignore NCSI traffic
Excluding certain packet types from triggering the connection to dial
Depending on your environment, you might prefer to exclude certain types of traffic passing through the router from triggering the
data connection. You can tell the router to ignore outbound TCP, UDP or ICMP packets. When any of these options are checked
the router will not dial a connection when that type of outbound destined data packet reaches the router from a locally connected
device.
Figure 23 – Connect on demand - Excluding IP protocols
Excluding certain application types from triggering the connection to dial
Some devices may generate general traffic as a part of normal operation which you may not want to trigger the data connection.
You can set the router to ignore Domain Name System (DNS), Network Time Protocol (NTP) or Microsoft network awareness (NCSI)
traffic from devices behind the router. When you check the box for these options, it tells the router to ignore the request from that
application type and will not dial a connection when this data type is received.

DESCRIPTION
On data activity, stay online for at least
When traffic as per the configured settings above appear, the router will either continue to stay
online, or dial a connection and will not disconnect it for the specified time period (min. 1 minute,
max. 1 hour). This timer is continuously reset throughout the duration of a dial-up session, whenever
data activity is detected matching the rules above.
After connecting, stay online for at least
This timer configures the router to not hang-up the connection for the specified time period after
initially dialling the connection. This setting cannot be less than the keep online period above. This
timer affects the connection only once per dial up session, at the beginning of the session.
After hanging up, don’t redial for
After a connection has been disconnected, you can tell the router to rest for a period of time before
re-dialling.
Disconnect regardless of traffic after
Forces the router to disconnect the connection regardless of the traffic passing through it. The
default setting is
never
.
Connect regularly, every / Randomise
connect frequency by up to
If you want to have the router dial a connection at regular intervals, use Connect regularly, every to
specify the interval between dials. Setting this to
never
effectively disables this option.
The router also features the ability to randomise the time at which the first dial action is performed.
This is useful in situations such as where you have numerous routers in an area where a power
outage has occurred. Setting a random dial time helps to reduce network congestion when all the
routers are powered on so they do not all try to connect simultaneously.
When Connect regularly, every is set to at least 2 minutes, you are able to configure the router to
randomise the time it begins to dial. The randomised dial timer only affects the initial dial after the unit
powers on or after the settings are saved. For example, if you configure the router to dial every 2
minutes with a randomised dial starting time of 1 minute, the router waits for the Connect regularly,
every time (2 minutes) and then randomly selects a time less than or equal to the Randomise connect
frequency by up to time (1 minute). After the randomly selected time has elapsed, the router dials
the connection. After the first dial, the router dials the connection every 2 minutes, ignoring the
Randomise connect frequency by up to time.
Setting timers for connection and disconnection
The router has a number of timer settings which let you determine when a connection is dialled and when it is disconnected.
Figure 25 – Connect on demand - Connect and disconnect timers
Table 12 - Connect on demand - Connect and disconnect timers descriptions
Verbose mode
The router provides the option of logging all the data activity which matches the settings for the Connect on demand feature for
advanced troubleshooting purposes. To enable the logging of the Connect on demand feature, click the Enable verbose mode
toggle key to switch it ON. See the System log section for more information.

Operator settings
The Operator settings page enables you to select which frequency band you will use for your connection and enables you to scan
for available network operators in your area.
Figure 29 - Band settings
Note: In order to change the operator’s band settings, the data connection must be disabled. When you access this page,
you are prompted to disable the data connection if it is already active.
You may want to do this if you’re using the router in a country with multiple frequency networks that may not all support High Speed
Packet Access (HSPA). You can select the router to only connect on the network frequencies that suit your requirements.
Use the Change band drop down list to select the band you wish to use.
The following band settings options are available:
It is not necessary to change the default setting of All bands in most cases. In fact, locking to a particular band can cause
connection difficulties if the device is moved to a location where the forced band selection is no longer available.
When All bands is selected, the router attempts to find the most suitable band based on the available networks for the inserted SIM
card.
The “2G all”, “WCDMA all”, “LTE all”, “3G/2G all” and “LTE/3G all” options allow you to force the device to lock to those particular
networks only.
Click the Save button to save and apply your selection.
Operator settings
The operator settings feature allows you perform a scan of available networks, and to optionally lock to a particular network
returned by the network scan. To scan for available networks, set the Select operator mode from automatic to Manual then click the
scan button. This operation can take a few minutes and requires that the packet data session be disconnected prior to scanning.

b) Enter the PIN in the Current PIN field and then enter it again in the Confirm current PIN field to confirm the PIN.
c) If you are placing the router in a remote, unattended location, you may wish to check the Remember PIN option. This
feature allows the router to automatically send the PIN to the SIM each time the SIM asks for it (usually at power up). This
enables the SIM to be PIN locked (to prevent unauthorised re-use of the SIM elsewhere), while still allowing the router to
connect to the cellular service.
When this feature is enabled, the PIN you enter when setting the Remember PIN feature is encrypted and stored locally on
the router. The next time the SIM asks the router for the PIN, the router decrypts the PIN and automatically sends it to the
SIM without user intervention.
When this feature is disabled and the SIM is PIN locked and the PIN must be manually entered via the router‘s
configuration interface. In situations where the router will be unattended, this is not desirable.
Note: Select Remember PIN if you do not want to enter the PIN code each time the SIM is inserted.

LAN
LAN configuration
The LAN configuration page is used to configure the LAN settings of the router and to enable or disable DNS Masquerading.
Figure 38 – LAN configuration settings
The default IP of the LAN port is 192.168.1.1 with subnet mask 255.255.255.0. To change the IP address or Subnet mask, enter
the new IP Address and/or Subnet mask and click the Save button.
Note: If you change the IP address, remember to reboot the router and enter the new IP address into your browser address
bar.
DNS masquerading
DNS masquerading allows the router to proxy DNS requests from LAN clients to dynamically assigned DNS servers. When enabled,
clients on the router’s LAN can then use the router as a DNS server without needing to know the dynamically assigned cellular
network DNS servers.
With DNS masquerading ON, the DHCP server embedded in the NTC-140W Series router hands out its own IP address (e.g.
192.168.1.1) as the DNS server address to LAN clients. The downstream clients then send DNS requests to the NTC-140W Series
router which proxies them to the upstream DNS servers.
With DNS masquerading OFF, the DHCP server hands out the upstream DNS server IP addresses to downstream clients directly,
so that downstream clients send DNS requests directly to the upstream DNS servers without being proxied by the NTC-140W
Series router.
You may also override the DNS Masquerading option by specifying custom DNS Server IP addresses in the DHCP Server
configuration mentioned in the next section of this guide. In this case the DHCP server assigns downstream devices the manually
configured addresses and the DNS Masquerading option is ignored.
In most cases, it is not necessary to disable DNS masquerading but if you need to, click the DNS masquerading toggle key to turn it
OFF and then click the Save button.

DHCP
The DHCP page is used to adjust the settings used by the router’s built in DHCP Server which assigns IP addresses to locally
connected devices.
DHCP relay configuration
In advanced networks configurations where the NTC-140W Series router should not be responsible for DHCP assignment, but
instead an existing DHCP server is located on the Wireless WAN or LAN connections, the clients behind the NTC-140W Series
router are able to communicate with the DHCP server when DHCP relay is enabled. This enables the NTC-140W Series router to
accept client broadcast messages and to forward them onto another subnet.
To configure the router to act as a DHCP relay agent click the DHCP relay toggle key to turn it ON and enter the DHCP server
address into the DHCP server address field. DHCP relay is disabled by default.

Routing
Static
Static routing is the alternative to dynamic routing used in more complex network scenarios and is used to facilitate communication
between devices on different networks. Static routing involves configuring the routers in your network with all the information
necessary to allow the packets to be forwarded to the correct destination. If you change the IP address of one of the devices in the
static route, the route will be broken.
Some routes are added by default by the router on initialization such as the Ethernet subnet route for routing to a device on the
Ethernet subnet.192
Adding Static Routes
To add a new route to the static routing list, click the +Add button. The Static routes page appears.
1. In the Route name field, type a name for the route so that it can be identified in the static routing list.
2. From the Network interface drop down list, select the interface for which you would like to create a static route.
3. In the Destination IP address field, enter the IP address of the destination of the route.
4. In the IP subnet mask field, enter the subnet mask of the route.
5. In the Gateway IP address field, enter the IP address of the gateway that will facilitate the route.
6. In the Metric field enter the metric for the route. The metric value is used by the router to prioritise routes. The lower the
value, the higher the priority. To give the route the highest priority, set it to 0.

RIP
RIP (Routing Information Protocol) is used for advertising routes to other routers. Thus all the routes in the router’s routing table will
be advertised to other nearby routers. For example, the route for the router’s Ethernet subnet could be advertised to a router on the
PPP interface side so that a router on this network will know how to route to a device on the router’s Ethernet subnet. Static routes
must be added manually according to your requirements. See Adding Static Routes.
Note: Some routers will ignore RIP.

To enable Routing Information Protocol (RIP)
1. Click the RIP toggle key to switch it to the ON position.
2. Using the Version drop down list, select the version of RIP that you would like to use.

Redundancy (VRRP) configuration
Virtual Router Redundancy Protocol (VRRP) is a non-proprietary redundancy protocol designed to increase the availability of the
default gateway servicing hosts on the same subnet. This increased reliability is achieved by advertising a “virtual router” (an
abstract representation of master and backup routers acting as a group) as a default gateway to the host(s) instead of one physical
router. Two or more physical routers are then configured to stand for the virtual router, with only one doing the actual routing at any
given time. If the current physical router that is routing the data on behalf of the virtual router fails, an arrangement is made for
another physical router to automatically replace it. The physical router that is currently forwarding data on behalf of the virtual router
is called the master router.
Master routers have a priority of 255 and backup router(s) can have a priority between 1 and 254.
A virtual router must use 00-00-5E-00-01-XX as its (MAC) address. The last byte of the address (XX) is the Virtual Router Identifier
(VRID), which is different for each virtual router in the network. This address is used by only one physical router at a time, and is the
only way that other physical routers can identify the master router within a virtual router.
To configure VRRP, configure multiple devices as follows and connect them all via an Ethernet network switch to downstream
devices.
1. Click the Redundancy (VRRP) toggle key to activate VRRP.
2. In the Virtual ID field, enter an ID between 1 and 255. This is the VRRP ID which is different for each virtual router on the
network.
3. In the Router priority field, enter a value for the priority – a higher value is a higher priority.
4. The Virtual IP address field is used to specify the VRRP IP address – this is the virtual IP address that both virtual routers
share.
5. Click the Save button to save the new settings.
Note: Configuring VRRP changes the MAC address of the Ethernet port and therefore if you want to resume with the web
configuration you must use the new IP address (VRRP IP) or on a command prompt type:
arp –d <ip address>

Port Forwarding
The Port forwarding list is used to configure the Network Address Translation (NAT) rules currently in effect on the router.
Figure 62 – Port forwarding list
The purpose of the port forwarding feature is to allow mapping of inbound requests to a specific port on the WAN IP address to a
device connected on the Ethernet interface.
Adding a port forwarding rule
To create a new port forwarding rule:
1. Click the +Add button. The port forwarding settings screen is displayed.
2. Use the Protocol drop down list to select the type of protocol you want to use for the rule. The protocols selections
available are TCP, UDP and All.
3. In the Source IP Address field, enter a “friendly” address that is allowed to access the router or a wildcard IP address
(0.0.0.0) that allows all IP addresses to access the router.
4. The Source Port Range (From) and (To) fields are used to specify the port(s) on the source side that are to be forwarded.
This allows you to send a range of consecutive port numbers by entering the first in the range in the (From) field and the
last in the range in the (To) field. To forward a single port, enter the port in the (From) field and repeat it in the (To) field.
5. In the Destination network address field, enter the IP address of the client to which the traffic should be forwarded.
6. The Destination Port Range (From) and (To) fields are used to specify the port(s) on the destination side that are to be
forwarded. If the Source port range specifies a single port then the destination port may be configured to any port. If the
Source port range specifies a range of port numbers then the Destination port range must be the same as the Source port
range.

DMZ
The Demilitarized Zone (DMZ) allows you to configure all incoming traffic on all protocols to be forwarded to a selected device
behind the router. This feature can be used to avoid complex port forwarding rules, but it exposes the device to untrusted networks
as there is no filtering of what traffic is allowed and what is denied.
The DMZ configuration page is used to specify the IP Address of the device to use as the DMZ host.

Router firewall
The Router firewall page is used to enable or disable the in-built firewall on the router. When enabled, the firewall performs stateful
packet inspection on inbound traffic from the wireless WAN and blocks all unknown services, that is, all services not listed on the
Services configuration page of the router.
With respect to the other Routing options on the Networking page, the firewall takes a low priority. The priority of the firewall can be
described as:
DMZ > MAC/IP/Port filtering rules > MAC/IP/Port filtering default rule > Router firewall rules
In other words, the firewall is of the lowest priority when compared to other manual routing configurations. Therefore, a MAC/IP/Port
filtering rule takes priority in the event that there is a conflict of rules. When DMZ is enabled, MAC/IP/Port filtering rules and the
router firewall are ignored but the router will still honour the configuration of the Remote router access control settings listed under
Administration Settings.

MAC / IP / Port filtering
The MAC/IP/Port filter feature allows you apply a policy to the traffic that passes through the router, both inbound and outbound, so
that network access can be controlled. When the filter is enabled with a default rule of “Accepted”, all connections will be allowed
except those listed in the “Current MAC / IP / Port filtering rules in effect” list. Conversely, when the default rule is set to “Dropped”,
all connections are denied except for those listed in the filtering rules list.
Figure 66 - MAC / IP / Port filtering
Note: When enabling MAC / IP / Port filtering and setting the default rule to “Dropped”, you should ensure that you have
first added a filtering rule which allows at least one known MAC/IP to access the router, otherwise you will not be able to
access the user interface of the router without resetting the router to factory default settings.
Creating a MAC / IP / Port filtering rule
To create a filtering rule:
1. Click the MAC / IP / Port filtering toggle key to switch it to the ON position.
2. Using the Default rule (inbound/forward) drop down list, select the default action for the router to take when traffic reaches
it. By default, this is configured to Accepted. If you change this to Dropped, you should first configure a filter rule that
allows at least one device access to the router, otherwise you will effectively be locked out of the router.
3. Click the Save button to confirm the default rule.

VPN
A Virtual Private Network (VPN) is a tunnel providing a private link between two networks or devices over a public network. Data to
be sent via a VPN needs to be encapsulated and as such is generally not visible to the public network.
The advantages of a VPN connection include:
Data Protection
Access Control
Data Origin Authentication
Data Integrity
Each VPN connection has different configuration requirements. The following pages detail the configuration options available for the
different VPN connection types.
Note: The following descriptions are an overview of the various VPN options available. More detailed instructions are
available in separate whitepapers on the NetComm Wireless website.
IPSec
IPSec operates on Layer 3 of the OSI model and as such can protect higher layered protocols. IPSec is used for both site to site
VPN and Remote Access VPN. The NTC-140W Series router supports IPsec end points and can be configured with Site to Site
VPN tunnels with third party VPN routers.

7. From the Authentication type drop down list, select the Authentication type used on the server. If you do not know the
authentication method used, select any and the router will attempt to determine the correct authentication type for you.
There are 5 authentication types you can choose from:
CHAP – uses a three way handshake to authenticate the identity of a client.
MS-CHAP v1 – This is the Microsoft implementation of the Challenge Handshake Authentication Protocol for which
support was dropped in Windows® Vista.
MS-CHAP v2 - This is the Microsoft implementation of the Challenge Handshake Authentication Protocol which was
introduced in Windows® NT 4.0 and is still supported today.
PAP – The Password Authentication Protocol uses a password as a means of authentication and as such, is
commonly supported. PAP is not recommended because it transmits passwords unencrypted and is not secure.
EAP – Extensible Authentication Protocol. An Authentication protocol commonly used in wireless networks.
8. The metric value helps the router to prioritise routes and must be a number between 0 and 65535. The default value is 30
and should not be modified unless you are aware of the effect your changes will have.
9. The Use peer DNS option allows you to select whether the remote clients will use the Domain Name Server of the PPTP
server. Click the toggle key to set this to ON or OFF as required.
10. NAT masquerading allows the router to modify the packets sent and received to inform remote computers on the internet
that packets originating from a machine behind the router actually originated from the WAN IP address of the router’s
internal NAT IP address. Click the toggle key to switch this to the ON position if you want to use this feature.
11. Set default route to PPTP sets all outbound data packets to go out through the PPTP tunnel. Click the toggle key to
switch this to the ON position if you want to use this feature.
12. The Verbose logging option sets the router to output detailed logs regarding the PPTP connection in the System Log
section of the router interface.
13. The Reconnect delay is the time in seconds that the router will wait before attempting to connect to the PPTP server in the
event that the connection is broken. The minimum time to wait is 30 seconds so as to not flood the PPTP server with
connection requests, while the maximum time to wait is 65335 seconds.
14. The Reconnect retries is the number of connection attempts that the router will make in the event that the PPTP
connection goes down. If set to 0, the router will retry the connection indefinitely, otherwise the maximum number of times
to retry cannot be greater than 65335.
15. Click the Save button to save the changes. The VPN will attempt to connect after your click Save. Click the Status button

Data stream manager
The data stream manager provides you with the ability to create mappings between two endpoints on the router. These endpoints
may be physical or virtual, for example, a serial port connected to the router’s USB port could be configured as an endpoint or you
could configure a TCP Server as an endpoint. You can then configure a virtual data tunnel or “stream” between the endpoints.
The data stream manager provides a wide range of possibilities and expands upon simple PAD functionality to include the
forwarding and translation of data between any of the endpoints. For example, you could send the GPS data from the built-in
module to a TCP server running on the router. In each case, the logical flow of the stream is from Endpoint A to Endpoint B.
Customers interested in developing their own applications to create custom endpoints and streams can contact NetComm Wireless
about our Software Development Kit.
Endpoints
The first thing to be done in order to create a data stream is to define the endpoints. There are 6 types of endpoint that may be
configured:
Serial port (generic)
TCP Server
TCP Client
UDP Server
UDP Client
GPS Data (for devices with GPS receiver)
Figure 85 - Endpoints list

To create an endpoint:
1. Click the +Add button on the right side of the page. A pop-up window appears.
Figure 86 - Creating an endpoint
2. In the Endpoint name field, type a name for this endpoint. The name can contain alphanumeric characters only i.e. A-Z, a-
z, 0-9.
3. Use the Endpoint types drop down list to select the type of endpoint to configure.
Serial port (generic): When a USB to Serial cable is used, this creates a generic serial port as an endpoint defaulting to the
commonly used settings as shown below.
TCP server: This creates a TCP server endpoint with the following options available.

TCP client: This creates a TCP client endpoint with the following options available. The retry timeout period specifies the
number of seconds to wait between attempts to re-establish a connection in the event that it is lost. The client will attempt
re-connection indefinitely every Retry timeout interval.
Figure 89 - TCP client endpoint configuration
UDP server: This creates a UDP server endpoint with the following options available.

Notes on data stream operation:
When any changes to the Data stream manager configuration are detected, all data streams are stopped and
restarted as per the new configuration.
Multiple Modbus clients cannot connect simultaneously to Modbus serial slaves connected to the router.
GPS data: This creates a GPS data endpoint.
Figure 92 - GPS data endpoint configuration
4. Click the OK button. The router displays a screen with configuration options for your chosen endpoint type.
5. Enter the options for your endpoint as required.
6. Click the Save button. The Endpoints list is displayed with the newly created endpoint listed and a summary of the settings
your configured.
Figure 93 - Endpoints list
Streams
When you have created the required endpoints, you can then proceed to set up a data stream. A data stream sends data from one
endpoint to another, performing any transformation of the data as required. When a stream is added, an underlying process on the
router checks the validity of the stream, checking for conflicts and illogical configurations.
Every stream requires two endpoints, Endpoint A and Endpoint B. In all cases, the flow of data is from Endpoint A to Endpoint B.
To create a new stream:
7. Click the +Add button on the right side of the page.
The Edit data stream page is displayed.
8. In the Data stream name field, enter a name for the Data stream.
9. Under Endpoint A, use the Endpoint name drop down list to select one of the endpoints you created previously. This
endpoint should be the starting point of the stream. Use the Mode drop down list to select the mode of operation of the
endpoint. The mode can be thought of as a transformation of the data as it leaves this endpoint. For example, if Endpoint
A type is Serial port (generic), the Mode can be set to various Modbus server and client types. This means that upon arrival
at Endpoint A, the data will be transformed into the chosen Modbus format, ready to be sent to Endpoint B.

PADD
PAD Daemon is a tool used to encapsulate raw serial data into a TCP packet to be transported over IP to another end point. The
server receiving the TCP packets unpacks the data and the original raw serial data is passed out of its serial port to the attached
device, thereby creating an invisible IP network to the two serial devices.
The PAD Daemon runs as a background process which can be accessed via the web configuration interface. The PADD
configuration page is located under “Services > PADD”. The PADD is used usually with multiple connections or when redundant
connections are needed. The PADD has two modes: the PADD TCP/IP Server mode and PADD TCP/IP Client Mode. When PADD
is enabled, both the PADD server mode and PADD client mode can be run at the same time.
The PADD configuration page is shown below.

To access the TR-069 configuration page, click the Services menu item, then select the TR-069 menu item on the left.
The TR-069 (Technical Report 069) protocol is a technical specification also known as CPE WAN Management Protocol (CWMP). It
is a framework for remote management and auto-configuration of end-user devices such as customer-premises equipment (CPE)
and Auto Configuration Servers (ACS). It is particularly efficient in applying configuration updates across networks to multiple CPEs.
TR-069 uses a bi-directional SOAP/HTTP-based protocol based on the application layer protocol and provides several benefits for
the maintenance of a field of CPEs:
Simplifies the initial configuration of a device during installation
Enables easy restoration of service after a factory reset or replacement of a faulty device
Firmware and software version management
Diagnostics and monitoring
Note: You must have your own compatible ACS infrastructure to use TR-069. In order to access and configure the TR-069
settings you must be logged into the router as the root user.
Note: When a factory reset of the router is performed via TR-069, the TR-069 settings are preserved.

The New message page can be used to send SMS text messages to a single or multiple recipients.
A new SMS message can be sent to a maximum of 9 recipients at the same time. After sending the message, the result is displayed
next to the destination number as “Success” or “Failure” if the message failed to send. By default, only one destination number field
is displayed. Additional destination numbers may be added one at a time after entering a valid number for the current destination
number field. To add a destination number, click the button and to remove the last destination in the list, click the button.
Destination numbers should begin with the “+” symbol followed by the country calling code. To send a message to a destination
number, enter the “+” symbol followed by the country calling code and then the destination number.
For example:
To send a message to the mobile destination number 0412345678 in Australia (country calling code 61), enter
“+61412345678”.
After entering the required recipient numbers, type your SMS message in the New message field. As you type your message, a
counter shows how many characters you have entered out of the total number available for your chosen encoding scheme. When
you have finished typing your message and you are ready to send it, click the Send button.

Diagnostics
The Diagnostics page is used to configure the SMS diagnostics and command execution configuration. This allows you to change
the configuration, perform functions remotely and check on the status of the router via SMS commands.
To access the Diagnostics page, click on the Services menu item then select the SMS menu on the left and finally select
Diagnostics beneath it.
SMS diagnostics and command execution configuration
The options on this page are described below.
Enable remote diagnostics and command execution
Enables or disables the remote diagnostics feature. If this setting is enabled all incoming text messages are parsed and tested for
remote diagnostics commands.
If remote diagnostics commands are found, the router executes those commands. This feature is enabled by default. All remote
diagnostic commands that are received are stored in the Inbox.
Note: It is possible to adjust settings and prevent your router from functioning correctly using remote diagnostics. If this
occurs, you will need to perform a factory reset in order to restore normal operation.
We highly recommended that you use the white list and a password when utilising this feature to prevent unauthorised
access. See the White list description for more information.

UM-00009
Only accept authenticated SMS messages
Enables or disables checking the sender’s phone number against the allowed sender white list for incoming diagnostics and
command execution SMS messages.
If authentication is enabled, the router will check if the sender’s number exists in the white list. If it exists, the router then checks the
password (if configured) in the incoming message against the password in the white list for the corresponding sending number. If
they match, the diagnostic or command is executed.
If the number does not exist in the white list or the password does not match, the router does not execute the incoming diagnostic
or command in the SMS message.
This is enabled by default and it is strongly advised that you leave this feature enabled to maintain security.
Send Set command acknowledgement replies
The NTC-140W Series router will automatically reply to certain types of commands received, such as
commands. However acknowledgement replies from the NTC-140W Series router are optional with
Wakeup
SMS Wakeup command. If disabled, the router does not send any acknowledgement after execution of a
Wakeup command. All acknowledgment replies are stored in the Outbox after they have been sent. This can be useful to determine
if a command was received and executed by the router. This option is disabled by default.
Access advanced RDB variables
By default, this option is turned off and only allows access to the basic RDB variables listed later in this guide. If this option is
enabled, you are able to access the full list of RDB variables via SMS.
Allow execution of advanced commands
By default, this option is turned off and only allows execution of the basic commands listed later in this guide. If this option is
enabled, you are able to execute advanced commands such as those which are common to the Linux command line. For example:
“execute ls /usr/bin/sms*” to list the contents of the /etc folder on the router.
Send acknowledgement replies to
This option allows you to specify where to send acknowledgment messages after the execution of a
If a fixed number is selected, the acknowledgement message will be sent to the number defined in the Fixed number to send replies
to field. If the sender’s number is selected, the acknowledgement message will be sent to the number that the SMS diagnostic or
command message originated from. The default setting is to use the sender’s number.
Fixed number to send replies to
This field defines the destination number to which error messages are sent after the execution of a
field is only displayed when Send Error SMS to is set to Fixed Number.

are stored in the Outbox after they have been sent.
Send error replies to
When Send Error SMS for Get/Set/Exec Command is set to ON, this option is used to specify where the error SMS is sent. Use the
radio buttons to select either Fixed Number or SMS Sender Number. When set to SMS Sender Number the router will reply to the
originating number of the SMS diagnostic or command. When set to Fixed Number the router will send the error messages to the
number specified in the following field.
Send a maximum number of
You can set the maximum number of acknowledgement and error messages sent when an SMS diagnostic or command is
executed. The maximum limit can be set per hour, day, week or month. The router will send a maximum of 100 replies by default.
The number of messages sent is shown below the options. The total transmitted message count resets after a reboot or at the

White List for diagnostic or execution SMS
The white list is a list of mobile numbers that you can create which are considered “friendly” to the router. If Only accept
authenticated SMS messages is enabled in the diagnostics section, the router will compare the mobile number of all incoming
diagnostic and command messages against this white list to determine whether the diagnostic or command should be executed.
You may optionally configure a password for each number to give an additional level of security. When a password is specified for a
number, the SMS diagnostic or command message is parsed for the password and will only be executed if the number and
password match.
Figure 111 - White list for diagnostic or execution SMS
A maximum of 20 numbers can be stored on the router in the white list. To add a number to the white list, click the “+Add” button.
Figure 112 – Adding a number to the SMS white list
The White List numbers and passwords can be cleared by pressing the button to the right of each entry. To add a number to
the white list, enter it in the Destination number field and optionally define a password in the Password field. When you have finished
adding numbers click the Save button to save the entries.

Sending an SMS Diagnostic Command
Follow the steps below to configure the router to optionally accept SMS diagnostic commands only from authenticated senders and
learn how to send SMS diagnostic commands to the router.
1. Navigate to the Services > SMS messaging > Diagnostics page
2. Confirm that the Enable remote diagnostics and command execution toggle key is set to the ON position. If it is set to OFF
click the toggle key to switch it to the ON position.
3. If you wish to have the router only accept commands from authenticated senders, ensure that Only accept authenticated
SMS messages is set to the ON position. In the White list for diagnostic or execution SMS messages section, click the
+Add button and enter the sender’s number in international format into the Destination number field that appears. If you
wish to also configure a password, enter the password in the Password field corresponding to the destination number.
4. If you would prefer to accept SMS diagnostic commands from any sender, set the Only accept authenticated SMS
messages toggle key to the OFF position.
Note: An alternative method of adding a number to the white list is to send an SMS message to the router, navigate to
Services > SMS messaging > Inbox and then click the button next to the message which corresponds to the sender’s
number.
5. Click the Save button.
Types of SMS diagnostic commands
There are three types of commands that can be sent; execute, get and set. The basic syntax is as follows:
execute COMMAND
get VARIABLE
set VARIABLE=VALUE
If authentication is enabled, each command must be preceded by the password:
PASSWORD execute COMMAND
PASSWORD get VARIABLE
PASSWORD set VARIABLE=VALUE
The following are some examples of SMS diagnostic commands:
password6657 execute reboot
get rssi
set apn1=testAPNvalue
SMS acknowledgment replies
The router automatically replies to get commands with a value and execute commands with either a success or error response. Set
commands will only be responded to if the Send Set command acknowledgement replies toggle key is set to ON. If the Send
command error replies toggle key is set to ON, the router will send a reply if the command is correct but a variable or value is
incorrect, for example, due to misspelling.

Where “VARIABLE (x)” is the name of another value to be read
Where “VALUE” is the content to be written to the “VARIABLE”
Where “COMMAND” is a supported command to be executed by the device (e.g. reboot)
Where “PASSWORD” is the password (if configured) for the corresponding sender number specified in the White List
Multiple commands can be sent in the same message, if separated by a semicolon.
For Example:
get VARIABLE1; get VARIABLE2; get VARIABLE3
PASSWORD get VARIABLE1; get VARIABLE2
set VARIABLE=VALUE1 ; set VARIABLE2=VALUE2
PASSWORD set VARIABLE1=VALUE1; set VARIABLE2=VALUE2; set VARIABLE3=VALUE3
If required, values can also be bound by an apostrophe, double apostrophe or back tick.
For Example:
“set VARIABLE=’VALUE’”
“set VARIABLE=”VALUE””
“set VARIABLE=`VALUE`”
“get VARIABLE”

COMMAND NAME
DESCRIPTION
1
reboot
Immediately performs a soft reboot.
2
pdpcycle
Disconnects (if connected) and reconnects the data connection. If a profile number is selected in the
command, try to disconnect/reconnect the specified profile in case the profile is active. If no profile
number is selected, try to disconnect/reconnect the current active profile. Reports an error if no profile
number is selected and there is no currently activated profile.
3
pdpdown
Disconnects the PDP. If a profile number is selected in the command, the router tries to disconnect the
specified profile in case the profile is active. If no profile number is selected, try to disconnect the current
active profile. Reports an error if no profile number is selected and there is no currently activated profile.
4
pdpup
Reconnects the PDP. If a profile number is selected in the command, the router tries to connect with
the specified profile. If no profile number is selected, the router tries to connect to the last active profile.
The gateway will check the currently activated profile and disconnect this profile before executing the
command. The router reports an error if no profile number is selected and there is no stored last active
profile number.
5
factorydefaults
Performs a factory reset on the router. Be aware that this command also clears the SMS white list on
the router.
6
download
Performs a download and install of a Firmware Upgrade (.cdi), Config File (.tar.gz) or a help document
(.pdf) file.
If the file is a firmware image as in the case of a .cdi file, the router will apply the recovery image first and
then the main firmware image. The download location is specified immediately after the command and
may be from an HTTP or FTP source URL.
If the file is a .tar.gz file, the router will apply the file as a configuration file update for the device and
reboot afterwards.
If the file is a .pdf, the router will assume this is a user guide document and save it to the router and
make the file available for viewing via the help menu on the Web-UI.
Note: If your download URL includes any space characters, please encode these prior to transmission
according to RFC1738, for example:
ftp://username:password@serveraddress/directory%20with%20spaces/filename.cdi
Note: Authenticated FTP addresses may be used following the format as defined in RFC1738, for
example:
ftp://username:password@serveraddress/directory/filename.cdi
7
codconnect
Causes the router to activate the PDP context when the Connect on demand feature is enabled.
8
coddisconnect
Causes the router to de-activate the PDP context when the Connect on demand feature is enabled.
9
wakeup
This forces the default Data connection profile to connect if it is in a disconnected or waiting state.
There are two circumstances in which this command may be useful; where the default profile is enabled
but has been manually disconnected and if Connect on demand is enabled and the router is awaiting
packet of interest. In both of these situations, the wakeup command will cause the default PDP context
to activate.
10
ssh.genkeys
Instructs the router to generate new public SSH keys.
11
ssh.clearkeys
Instructs the router to clear the client public SSH key files.
A password (if required), only needs to be specified once per SMS, but can be prefixed to each command if desired.
“PASSWORD get Variable1”; “get VARIABLE2”
“PASSWORD set VARIABLE1=VALUE1”; “set VARIABLE2=VALUE2”
If the command sent includes the “reboot” command and has already passed the white list password check, the device keeps this
password and executes the remaining command line after the reboot with this same password.
For Example:
“PASSWORD execute reboot; getVariable1”; “get VARABLE2”
“PASSWORD execute reboot; PASSWORD get Variable1”; “get VARABLE2”
Note: Commands, variables and values are case sensitive.
List of basic commands
A list of basic commands which can be used in conjunction with the execute command are listed below:
“pdpcycle”, “pdpdown” and “pdpup” commands can have a profile number suffix ‘x’ added. Without the suffix specified, the
command operates against the default profile configured on the profile list page of the Web-UI.
