Host RJ-11 IP Gateway User Guide, version iii

CHAPTER 1 Introduction

Many existing meters, data loggers, RTU's, PLC's, point-of-sale, and other remote devices only
have physical interfaces designed to access the telephone network. They do not have serial or
Ethernet ports. They currently use analog cellular or standard phone lines to connect in circuit­switched mode for data transfer.

Analog cellular phone service is being discontinued. The combination of the Host RJ-11 IP Gate­way, RJ-11 IP Gateway, and the AirLink Raven-E enables remote connectivity between host appli­cations and these remote devices over cellular packet data networks. The RJ-11 IP Gateway
provides the bridge between a device requiring an RJ-11 interface and the Raven-E, with its Ether
net interface. The Host RJ-11 IP Gateway can provide Ethernet-based Internet connectivity to a
Legacy Host system with only RJ-11 ports.

Introduction

FIGURE 2. Host RJ-11 Gateway with an AirLink Raven-E and a Modem Router

Host RJ-11 IP Gateway Features

• One RJ-11 phone port

The phone port is a phone line designed to function just like standard wall-jack analog phone
line. It is designed primarily to connect dial-up devices, with internal modems, to the RJ-11 IP
Gateway, which then routes data from the devices over the network. The RJ- 1 1 IP Gat eway and
Host RJ-11 IP Gateway mimics the phone company, answering incoming calls and routing
them to an internal modem attached to the phone port, or generating calls from an internal
modem to an attached device.

Caution: The Host RJ-11 IP Gateway's RJ-11 phone port should never be con-

nected into the Public Switched Telephone Network (PSTN). This device is
designed to emulate the PSTN for other devices. The Host RJ-11 IP Gateway may
sustain damage not covered by warranty if it is connected to the Public Switched
Telephone Net work.

• One RJ-45 auto-sensing 10base-T Ethernet port

The Ethernet port is designed to be connected to either an AirLink modem with an Ethernet port
such as the Raven-E or Raven X or any Ethernet-based network. With the modem connected to
the cellular network, the communication from the device connected to the RJ-11 port can be
routed to the Internet and your remote host.

• One power connector

The Host RJ-11 IP Gateway uses a AC power adapter with an optional DC adapter available.

• Status LEDs

The Host RJ-11 IP Gateway status LEDs give clear and concise information about the operation
of the ports.

Host RJ-11 IP Gateway User Guide, version 4

CHAPTER 2 Installation

Configuring the Host RJ-11 IP Gateway to work with your network or Raven-E and your RJ-11
equipped device is easy. This chapter covers a basic configuration.

Caution: The Host RJ-11 IP Gateway’s RJ-11 port (labeled “Phone”) should not be

connected into the Public Switched T elephone Network. This port is the emulation
for a Phone that you would have been using with your device. The RJ-11 IP Gate
way will sustain damage not covered by warranty if it is connected to the Public
Switched Telephone Network.

Before You Start

-

Caution: If the Host RJ-11 IP Gateway and Raven-E (as applicable) are going to be

on a hub which is connected to a local network, you will need to be sure the
addresses you select are not used by any other device on the network. Consult with
your network administrator if you are unsure.

Software Required

• Wireless Ace - Graphical interface for configuring your Raven-E. Wireless Ace is located on

Host RJ-11 IP Gateway CD or you can download Wireless Ace from the AirLink website: http:/

/www.airlink.com/support/modems/utilities/. A default installation of this utility is assumed

later in these directions.
If you will not be connecting the Host RJ-11 IP Gateway to a Raven-E, you will not need Wire-

less Ace.

• Host RJ-11 IP Gateway Port Utility - Utility to establish an initial IP address for your Host

RJ-11 IP Gateway. The port utility is located on the Host RJ-11 IP Gateway CD or you can
download it from the AirLink website: ht tp://www.airlink.com/support/modems/rj-11-host.asp.
A default installation of this utility is assumed later in these directions.

If you will be connecting the Host RJ-11 IP Gateway to a Raven-E, you will not need the port
utility. If you can use the default IP address of the Host RJ-11 IP Gateway for the initial config
uration, you, also, will not need the port utility.

Hardware Required

• Ethernet Cable - A cross-over or straight through Ethernet cable.

-

Host RJ-11 IP Gateway User Guide, version 5

Installation

If you will be connecting the Host RJ-11 IP Gateway to a Raven-E, you will need a cross-over
Ethernet cable to configure your Raven-E unless your computer’s Ethernet port is auto-sensing.

The Host RJ-11 IP Gateway has an auto-sensing Ethernet port, you can use either a cross-over
cable or a straight-through Ethernet cable to connect the Host RJ-11 IP Gateway to the Raven-E
or your computer.

• Power supplies and a power source - Y ou will need a power supply and power source for both

the Host RJ-11 IP Gateway and the Raven-E (as applicable).

• PC or Laptop - To configure both the Host RJ-11 IP Gateway and the modem (as applicable),

you will need a computer with Internet Access, other than the cellular account, and an available
Ethernet port.

Cellular Account Required

• Cellular Account - If you will be connecting the Host RJ-11 IP Gateway to a Raven-E, you

need to already have an active account with a cellular provider and to have activated your
modem with that provider. The AirLink Raven-E is certified to work with a variety of cellular
providers.

If you need to activate your modem, you can use the Setup Wizard for your cellular provider
which you can obtain from the AirLink website: http://www.airlink.com/support/.

Important Information about Ports

• Port Blocking - Many cellular providers and other ISPs block ports below 1024 which are the

default ports for many server protocols (such as HTTP, telnet, and SSH). If your provider
blocks these ports, you will need to configure a port you can access.

Configuring your Raven-E for the Host RJ-11 IP Gateway

These steps are just a basic configuration to get you started and allow the Raven-E to connect with
the Host RJ-11 IP Gateway . Refer to the modem user guide for more configuration options for spe
cific environments.

Omit this section if you are not connecting your Host RJ-11 IP Gateway to a
Raven-E.

Default settings

• Management Interface IP Address: 192.168.13.31.

• Telnet and Wireless Ace password: 12345

• DHCP server: enabled.

• Public Mode - the IP Address assigned by the carrier is assigned to the Host RJ-11 IP Gateway.

http://166.213.236.221:9080

Commands

The Host RJ-11 IP Gateway can be configured to handle a variety of devices which need to connect
to an RJ-11 port.

If you’re using a Raven-E with the Host RJ-11 IP Gateway, for configuration
options for your Raven-E, refer to the modems’s user guide. All user guides are
available on the AirLink website: http://www.airlink.com/support.

Web-based Interface

Note: Screen shots in this guide are using Microsoft Internet Explorer, but you can

use any web browser to configure the Host RJ-11 IP Gateway.

The Host RJ-11 IP Gateway employs a web-based user interface. To access the web interface, you
will need to know the IP Address given to your Raven-E by the cellular carrier (or the modem
domain name if you have configured IP Manager settings for the modem). Type the IP address (or
modem domain name) into the Address bar of your web browser followed by “:9080” (see the
example below).

Since many cellular carriers block the standard web browser ports (80 and 8080),
the Host RJ-11 IP Gateway uses 9080 by default as a port for the web-based inter
face.

FIGURE 1. Web Browser: Enter the Location

The web interface for the Host RJ-11 IP Gateway, by default, has no security. If you made changes
to the security configuration (

Configuration Settings and Commands

• Ethernet Address: MAC Address of the Host RJ-11 IP Gateway.

• IP Address: The current IP Address of the Host RJ-11 IP Gateway and how the IP address was

assigned (in the example, a Raven-E in Public Mode used DHCP to give the Host RJ-11 IP
Gateway the IP addressed assigned by the cellular network).

• IP Netmask: The current subnetmask of the Host RJ-11 IP Gateway and how the device

obtained it.

Serial Settings

The Serial Settings page allows you to specify the baud rate, protocol, character size, parity, stop
bits, and flow control behavior for the RJ-11 port (Phone).

Note: For most configurations, the default settings (shown in the screen shots) are

best. Change these parameters only if you know the device you will be connecting
to the Host RJ-11 IP Gateway requires special settings.

FIGURE 4. Host RJ-11 IP Gateway: Serial Settings

• Enabling flow control enables it on both input and output.

• The inactivity time-out shuts down the service on the port if there is no input or output in the

specified time-out period.

Host RJ-11 IP Gateway User Guide, version 21

Configuration Settings and Commands

• With Modem Signal Loopbacks, the Host RJ-11 IP Gateway eliminates the use of specialized

cables required to change signal types and directions by performin g th e loopback of signal
types to other signal types internally.

• NativeCOM, (or any RFC-2217 Telnet client with COM-PORT-OP TION support) overrides the

baud rate, size, parity, stop bits and flow control parameters.

Port Services

By default, the RJ-11 port is configured to accept incoming TCP connections from TCP/telnet cli­ents with outgoing service based on phone numbers dialed by the attached device (Modem Ser­vice). You may configure the ports to initiate outgoing raw TCP or telnet connections to remote
servers. In addition, the modem emulation feature may be enabled to allow a serial port to mimic a
modem interface.

• When using the modem service on the port, the phone number will be translated to a host/port

pair then a TCP connection will be established to the remote host.

• When using outgoing connections on the port, the settings configured on the Serial Settings

page will be applied to the port, and a TCP connection will be established to the remote host.

• Once connected, data received on the port is sent to the remote server over the network connec-

tion and data received on the network connection is sent out the port.

FIGURE 5. Host RJ-11 IP Gateway: Port Services

• No Outgoing Service: Disables outgoing port services on the specified port. Incoming connec-

tions are still allowed. All port services options will reset to defaults.

• Modem Service: Enables modem emulation on both the incoming and outgoing network con-

nections. The target peer (specified in the Phone Number Translation table and configured in
the Protocol Settings page) determines the type of outgoing connection that will be made.

• Outgoing Network Connection: Enables an outgoing connection to the specified host.

• Outgoing Telnet Connection: Enables an outgoing telnet connection to the specified host.

• Modem Service Options: When Modem Service is selected, you may also configure the

Source TCP Port. In most cases, the value used for the source port is arbitrary and you can
leave this field set to 0 for “any”. However, if your server or firewall has specific requirements
you may specify an explicit source port number in the Source TCP Port field. If this port is not
available when the TCP service starts up, an error will occur and the TCP service will reset and
try again.

Phone Number Translation

This table can be used to translate phone numbers into IP addresses or Hostnames. If the attached
device dials one of the specified telephone numbers, the corresponding IP address and port are
used to make the TCP connection. Note that all non-numeric characters except the “,” (comma) in
the phone number are ignored.

When modem emulation is enabled, the Host RJ-11 IP Gateway can detect the phone number from
ATD commands. Although the IP address of the remote host can be embedded directly into the
ATD command, certain devices can't always be easily configured to do this.

FIGURE 6. Host RJ-11 IP Gateway: Phone Number Translation

The Default Translation entry is used if the dialed phone number is not found in the list. (The dial
backup number is not used in the Host RJ-11 IP Gateway.) The phone number table has a number
of features to ease initial configuration. When an attached device dials a number that is not in the
table, the device server creates a dummy entry in the table. This entry will consist of just the phone
number. Until you fill in the remainder of the entry (IP Address/Hostn ame an d Port) and save it,
this entry will not be used.

Once you have created and saved an entry in the table, a link to the associated entry on the Protocol
Settings page appears on the right. If the protocol is not yet defined, this link, “Define protocol”,
will create a new entry on the Protocol Settings page, otherwise the link will be “Edit protocol”.

The translation table screen allows you to add up to 5 new entries at a time. A total of 64 entries
may be configured including the default entry.

In the example above, if the attached device dials 18005551212, the port will be connected to the
host at 192.168.13.100 on TCP port 5004. This host is not yet defined, so it will use the default
TCP protocol. If the attached device dials any other number, the port will be connected to
default.eairlink.com:5003, whose protocol is defined. And the termin al has actually dialed 555­1212, generating an automatic, but not yet saved, entry.

Network Translation

The Host RJ-11 IP Gateway is capable of accepting incoming TCP connections and redirecting
them to remote TCP hosts. This functionality is called network translation and behaves much like a
TCP “pipe” between two systems. The Host RJ-11 IP Gateway also uses Network Translation to
allow connections to the web-base interface on a port other than the http protocol defined port of
80 which is frequently blocked by cellular carriers.

FIGURE 7. Host RJ-11 IP Gateway: Network Translation

It is also possible to modify the network protocol traveling through the TCP pipe by using the Pro­tocol Settings page to define the remote host's protocol requirements. The most common use for

this functionality is to add SSL encryption to an incoming TCP connection prior to sending it along
to the remote host.

The Network Translation table is used to define network mappings for TCP pi pe s. You must f irst
specify the incoming TCP port to which your device or application will connect. Then, you must
specify the outgoing hostname and destination TCP port for the TCP pipe.

You can also specify the source TCP port for the outgoing TCP connection. Usually , this should be
set to 0 to allow automatic selection of the source port. However, if you have a firewall that

Host RJ-11 IP Gateway User Guide, version 24

Configuration Settings and Commands

imposes limits on source TCP ports then you may need to set this to something specific. Note that
if you specify something other than 0, you will be limited to only 1 TCP pipe at-a-time for any
given destination port.

Protocol Settings

For each host (peer) you will make an outgoing connection to, you need to specify the protocol
options used for that host. For each host, select the Host from the “Edit settings for a different peer”
selection box. Select “Add a new peer definition” link to add a new host.

FIGURE 8. Host RJ-11 IP Gateway: Protocol Settings

The hosts are identified by their IP address or Hostname and TCP port. You may also specify wild
cards. Specific host names and/or port numbers take precedence over the wild cards. An asterisk
for the IP address/hostname (for instance “*:443”) means any other host when connecting on port

443. An asterisk for the port number (for instance “host.peer.com:*”) refers to any other port on
that host. And a double asterisk (“*:*”) refers to all other hosts.

Network Configuration

The Network Configuration group configures settings for the RJ-45 Ethernet port.

Network Settings

The Network Settings page allows you to set the IP address, the IP netmask, and the TCP keep­alive settings.

Every IP address contains two pieces of information: the network number and the host number. A
network number is assigned to each local area network and is shared by all the network devices on
that network. Each network device, or “host”, is assigned a unique host number. The IP netmask
defines which portion of an IP address contains the network number, and which portion contains
the host number. The default netmask depends on the “class” of the IP address that you are using.

Host RJ-11 IP Gateway User Guide, version 25

Configuration Settings and Commands

In one type of configuration, the Host RJ-11 IP Gateway has been designed to work in conjunction
with an AirLink Raven-E. The IP address for the Host RJ-11 IP Gateway and the IP address for the
Raven-E need to be on the same network. If you need to set a specific IP address for the Raven-E
and the Host RJ-11 IP Gateway , you will need to use Private Mode for the Raven-E. Setting Private
Mode is covered in the Raven-E User Guide.

FIGURE 9. Host RJ-11 IP Gateway: Network Interface Settings

TCP keep-alive is a standard feature of TCP/IP that can be configured to automatically monitor the
state of TCP connections. If one end of an idle TCP connection is severed (like by a network or
power failure), it is possible for the other end to remain open indefinitely. If a network host fails
while it has an open TCP connection to one of the device server’s serial ports, that serial port might
remain unavailable until it is manually reset.

The optional TCP keep-alive feature sends special “keep-alive” packets to the remote TCP host in
order to detect the situation where the remote host fails. If a failure is detected, the TCP connection
is reset to allow other hosts to access the serial port.

To enable TCP keep-alives on serial-related network connections, enter the total time (in seconds)
that you will allow TCP connections to remain idle before resetting them. The first keep-alive
packet will be sent after the connection has been idle for half of this total time. After that, four
more TCP keep-alive packets will be sent at regular intervals until a TCP response is received from
the remote host. If no response is received before the total keep-alive time runs out, the TCP con

-

nection will be reset.

Caution: Enabling TCP keep-alives will increase the amount of network traffic on

your network. Unless you have a specific need for this feature, it is best to leave it
disabled. If you do enable it, it is best to make the keep-alive time-out larger to
reduce network traffic.

Host RJ-11 IP Gateway User Guide, version 26

Configuration Settings and Commands

DNS Settings

The DNS Settings page allows you to specify a DNS name for your unit, specify the addresses of
DNS servers to resolve names, and to pre-define some host names. The DNS name and servers can
also be derived from a DHCP server.

FIGURE 10. Host RJ-11 IP Gateway: DNS Settings

If the device server is configured to use DHCP, it will try to get DNS configuration information
from the DHCP server. You may also manually set up static DNS entries on this page. Having DNS
configured allows you to specify names in place of IP addresses in your configuration.

The DNS Domain Name is used as the default domain for any names you specify. For instance, if
you specify the name “foo” in the ping command and the domain name “company.com” in the
DNS Domain Name above, the ping command will do a DNS lookup on the name “foo.com
pany.com”.

Host RJ-11 IP Gateway User Guide, version 27

-

Configuration Settings and Commands

The DNS Server IP Addresses are used to specify the addresses of one or more machines that can
be used to resolve names to IP addresses.

The Static Hosts entries are used to define local host name to IP address mappings.

IP Routing

The IP Routing page lets you configure network routes for accessing remote networks.

FIGURE 11. Host RJ-11 IP Gateway: IP Routing

If the device server is configured to use DHCP, it will try to get IP configuration information from
the DHCP server. You may also manually set up static routes on this page.

Each IP route consists of a destination IP address, a netmask, and a gateway IP address. Depending
on the netmask, the destination IP can specify one of two route types:

• Host route: This is a route to a specific IP host. The netmask is always 255.255.255.255.

• Network route: This is a route to an IP network. The netmask defines which portion of the des-

tination IP address contains the network number.

The current routing table is also displayed on this page for your reference.

Time Settings

The Time Settings page allows you to configure NTP or HTTP time-servers to get the system time
from. If you are using SSL for peer verification, the device server must obtain a valid time from an
external time-server to verify the peer.

Time is used in the system and other logs. Having the correct time can help to troubleshoot prob­lems or simply to track occurrences of particular events.

The current time is expressed in UTC (Coordinated Universal Time).

Host RJ-11 IP Gateway User Guide, version 28

Configuration Settings and Commands

FIGURE 12. Host RJ-11 IP Gateway: Time Settings

If the device server is configured to use DHCP, it will try to get NTP server information from the
DHCP server. You may also manually set up the addresses on this page. The NTP service uses
UDP port 123. If your device server is behind a firewall you may need to allow accesses to this port
through the firewall. Adding or changing the NTP server will trigger the Host RJ-11 IP Gateway to
get the time again.

The HTTP server you specify need not be a designated time server – just a reliable server. The
device server derives the system time from the HTTP header the server returns. Adding an HTTP
server will not automatically trigger getting the time. You must reboot for this to take effect.

Security Settings

The security settings page includes settings for the System Password and Network Isolation.

Host RJ-11 IP Gateway User Guide, version 29

Configuration Settings and Commands

FIGURE 13. Host RJ-11 IP Gateway: Security Sett ings

• System Password: The Host RJ-11 IP Gateway’s administrative functions can be protected by

a system password.
By default, no system password is configured. Once a password is set, your web browser will

prompt you for the system password whenever you try to access sensitive configuration pages.
The browser will ask for a username and password. The username is always “admin”. The pass
word will be what you configured.

• Network Isolation Configuration: By default, all network services are enabled. However, for

security, any or all listening services may be disabled. Unselect any services that you wish to
disable. These changes will not take effect until the next reboot.

Configuration Settings and Commands

Online Update

You may configure your device server to make a connection to an update server and obtain updated
software or configuration information from the server or send information to the server.

FIGURE 14. Host RJ-11 IP Gateway: Online Update -top half of the page P

T o configure updates, first, select the update server to use and the SSL parameters for connecting to
it. You may specify both the server name and the path for obtaining the updates. If the server
requires HTTP authentication from the device server, specify the username and password to use.

You can schedule the updates to happen periodically, or on every startup, or only when manually
selected. The automatic update capability can be used along with Network Isolation to provide a
way for the device server to “call out” to get updates if all the incoming connections are disabled.

FIGURE 15. Host RJ-11 IP Gateway: Online Update - middle of the page

Host RJ-11 IP Gateway User Guide, version 31

Configuration Settings and Commands

You can configure which items to send to the server or update from the server.

• Configuration Database – current settings on the unit

• System Log – trace activity

Items to Upload:

• Operating Software – the software running in the unit

• File System – SSL certificates

• Current Configuration – current settings on the unit

FIGURE 16. Host RJ-11 IP Gateway: Online Update - bottom of the page

• Test Configuration – check to make sure the settings are right and the server is available. This

will contact the server and go through the communication necessary to send and receive the
files without actually doing so.

• Update Now – contacts the server and sends and updates the files now.

• Save Changes – save changes for later.

Status and Logs

The status and log pages display system and operation information.

Troubleshooting

Significant events will be displayed for review. For a more complete report of events, see the sys­tem log.

System Log

By default, the device server stores informational and error messages in the system log. You can
also configure the device server to record debug trace data in this system log buffer (
and Settings” on page 35.). The log file is displayed with color-coding to make it easier to spot spe­cific entries.

See “Log Files

You can save the System Log to a file to review separately. You can also clear the log, but there is
no confirmation on clearing the stored log file.

FIGURE 18. Host RJ-11 IP Gateway: System Log

Port Status

The current status of the RJ-11 port is displayed.

Host RJ-11 IP Gateway User Guide, version 33

Configuration Settings and Commands

FIGURE 19. Host RJ-11 IP Gateway: Port Status

The DCD, RTS, CTS, DTR, DSR, and RI columns indicate the status of the modem signals for the
RJ-11 (phone) port. If the modem signal is present (either asserted if it is an outgoing signal, or
detected if it is an incoming signal) its name will appear in the corresponding column.

The State column indicates whether the port is open, closed, waiting for DCD, or experiencing any
notable conditions (such as flow control). The Serial Parameters column indicates the current set
tings for the port.

-

Note: The Serial Parameters column reflect the actual, real-time serial settings in

use by the port. The settings that are specified via the serial configuration pages are
applied each time the port is opened. If the port is closed, the serial parameters
reported by Port Status may not necessarily match the settings you configured until
the port is re-opened. Furthermore, some clients (like NativeCOM) can override
the configured settings.

The Input, Output, Parity Errors, Framing Errors, and Overrun Errors columns are tallies of activ­ity on the port. Under each port row is a field indicating the current TCP connection status on the
port.

The display will update automatically every few seconds. You can stop the automatic update by
selecting “Stop” from your browser. To restart the updating, select “Refresh” or “Reload” from
your browser.

OS and Network Information

The OS Information shows the current state of system and application tasks as well as memory
usage information.

The Network Information displays the status of network services and current connections. The
TCP Sockets section shows current connections and TCP listeners. The UDP Listeners section
shows UDP ports that are active.

The Network Interfaces displays the status of the currently active interfaces on the unit. This is
similar to the “ipconfig” command on a Windows machine or the “ifconfig” command on a Unix
machine. The current routing table is displayed as well.

Log Files and Settings

This page has two parts, Enabling Logging (Log settings) and Emailing Debug information.

By default, the Host RJ-11 IP Gateway stores informational and warning messages in the system
log. You can also configure the Host RJ-11 IP Gateway to save trace data in this system log buffer.

FIGURE 20. Host RJ-11 IP Gateway: Log Settings

Tracing is generally used for troubleshooting problems. For port tracing, you must select both the
port (phone) and the events that you want to trace.

You can also select additional log file generation, either a log file for the Ethereal Network Proto­col Analyzer or a WAV file for later analysis. Selecting “modem.wav” will record the latest modem
negotiation from the RJ-11 port (from the time it dials until it completes negotiation).

For the additional log file generation, you will need to specify an email address for the recipient as
well as your own email information.

allow relaying through their host.

Commands

The Host RJ-11 IP Gateway has some built in commands available.

Ping

You can use the Ping command to test a network connection.

FIGURE 22. Host RJ-11 IP Gateway: Ping

Enter the IP address to Ping or a Hostname and the Number of Pings then press the Ping button.
The command will display the results as follows:

Response from 209.75.217.6: icmp_seq=9, time=10.0 ms
10 packet(s) transmitted, 10 packet(s) received, 0% packet loss.

Not all hosts accept ICMP pings even if they are present on the network. However, the ping com­mand can serve two functions: 1) to test your general network settings – IP address, network mask,
gateway and DNS server and 2) whether the device server can reach a given host. Simply resolving
a name to an IP address effectively tests the first function.

Note: Some cellular carriers block ICMP pings on their cellular network.

Reset/Reboot

The Reset/Reboot page lets you reset the phone (RJ-11) port or the entire Host RJ-11 IP Gateway.

FIGURE 23. Host RJ-11 IP Gateway: Reset/Reboot

You can reset the phone port by selecting the port and pressing the Reset Port(s) button. This will
kill whatever service was on the port and reset it back to the current configuration settings.

You may reboot the entire device by pressing the Reboot button. This is the equivalent of power
cycling the unit.

APPENDIX B AT Commands

In addition to the web-based interface, you can use some typed AT Commands with the Host RJ-11
IP Gateway. To enter AT commands, you need to be connected to the device via telnet or by using
the RJ-11 port as you would a standard analog modem.

All AT command strings, with the exception of the break sequence (“+++”) and the repeat com­mand (“A/”), must be terminated with the command line termination character, defined in S3
(default is CR). All characters before 'AT' are ignored. Unsupported commands are ignored and
generate an “OK” result code. Multiple commands may be combined on a single line, however the
AT command string is currently limited to 40 characters.

Modem Signal Behavior

The RJ-11 IP Gateway is not a modem (DCE), but is a terminal (DTE) device. It is designed to be
connected to another DTE device via RJ-11 cable.The RI (Ring Indicator) signal does not have a
corresponding outgoing signal so it is not supported.

Specifically, the DTR, DSR and DCD signals should be crossed with the device as follows:

Device RJ-11 IP Gateway

DCD,DSR DTR
DTR DCD,DSR

To emulate a modem properly, the Host RJ-11 IP Gateway does the following:

Mode Modem DCD Settings Behavior

Command/Data Always on (&C0) DTR is asserted
Command/Data Follow connection (&C1) DTR is asserted only when TCP/IP connection is

present and has been accepted via ATA or auto­answer. DTR is de-asserted when connection is
lost

The device server monitors its DCD signal in order to detect changes in the device's DTR signal.
The following behaviors occur on loss of DCD only.

Mode Modem DTR Settings Response to loss of DCD

Offline AT&D0 Ignore
Offline AT&D1 Ignore
Offline AT&D2 Ignore
Online AT&D0 Ignore
Online AT&D1 Drop to command mode, preserving connection
Online AT&D2 Drop to command mode, terminating any connec-

tion

Phone Numbers

The “phone number” used in an outgoing connection for an “A TD” command may be a real phone
number that is translated to an IP/port pair (see Phone Number Translation) or it consists of an IP
address and optional port number. All leading non-numeric characters (such as the T or P dial mod
ifiers) are ignored. A number of formats are accepted for the “IP” phone number.

Format Example Notes

Dotted decimal a.b.c.d or 192.168.1.1 Numbers are from 0 to 255
