2. Quick Installation

2. 1 Connectors

There are five connectors on AX-112, and you can find them on the two
side panels. These two side panels can be distinguished by the arrow icon,
the upward arrow indicates the WAN side, while the other downward arrow
indicates the LAN side.

2.1.1 WAN side connectors

PWR

DC power jack

Use the universal power adapter included in the package. The adapter is a
high quality switching power device which accepts 100~240VAC input, and
5VDC output with 2A rating. If you have to use a substitute power adapter,
use an adapter of good quality and with the correct rating. Incorrect voltage
adapter output may damage the AX-112, and poor quality adapter may induce
unacceptable ripple noise to the phone set.

PSTN
(FXO)

WAN

RJ45 WAN

Normally, this port is connected to your broadband Ethernet port which could be

xDSL, cable modem or your ofce LAN. You have to assign an IP to the WAN port

of AX-112, or enable its DHCP client to get an IP from your DHCP server.

RJ11 line port

The line port is used for connecting to the PSTN line. It is also called as the Foreign

Exchange Ofce (FXO) port. This line port on AX-112 only has bypass function

without the DAA circuit. This means that it can relay the incoming call from PSTN
to the phone set connected to the phone port, but the VoIP call can not go through
by this line port.

LAN

PHONE (FXS)

LAN

Normally, you can only have one Ethernet cable at your desk. If you also have
to use your PC or notebook while the VoIP device is running, then an extra LAN
port is necessary for this purpose on AX-112. The LAN port has bridge capability
to WAN port and allows the connected device to be able to access the network
easily without other settings.

RJ11 phone port

AX-112 needs an ordinary phone set to work as an IP phone, and the RJ11
phone port is used for this purpose. Any ordinary analog phone set could be plug
into this jack. Then you may make the VoIP call, or switch the connection to the
PSTN (Public Switched Telephone Network) line and make a normal local phone
call. You can make the connection switch from the VoIP to the PSTN line through
pressing the special codes on the phone keypad. The default PSTN access code

is “*0” and it is user congurable.

Reset button

You may nd the Reset button at the bottom of the case. Press the button, with a

small rod or pen, and hold for 5 seconds to restore the factory default settings.

2. 2 Hardware connection

• Use a standard Category 5 (CAT5) Ethernet cable with RJ45 jack to
connect the WAN port of AX-112 to the LAN port of your ADSL modem or
router.

• Use another Ethernet cable to connect your PC or notebook to the LAN
port of AX-112 if necessary.

• Use an ordinary phone cable with RJ11 jack to connect the phone-set to

AX-112’s phone port.

• Use another phone cable with RJ11 jack to connect the AX-112’s line port

to your PSTN jack if necessary. The PSTN jack is normally on the wall.

• Connect the power adapter, and then refer to the next section for how to
assign an IP address to the WAN port for future operation.

2. 3 WAN IP assignment

After you have correctly set up the hardware connection, the next step is

the WAN port IP assignment. You may assign a xed IP address to AX-112

or enable its DHCP client to get an IP address from your DHCP server.

At the rst stage of assigning an IP address to the WAN port, you may get the IP

address by using the phone-set and entering the proper DTMF code command.
AX-112 will the report the WAN address for you by voice. You may access the

WAN port’s IP address via IVR. Follow the instructions below:

1. Pick up the phone and dial “****”; and

2. After hearing the voice menu, dial “100#”. You should hear the WAN

status reported by voice.

By default, the AX-112’s WAN port is set to the DHCP client mode. If there is no
DHCP server in your network, you can assign a xed IP address for AX-112 via
IVR. Refer to the Chapter 4 for more information on how to congure the IVR.

Chapter3-Conguration

3. Conguration

In an Internet browser, enter the WAN IP address that you got either via the

DHCP server or the IVR). You will be taken to the AX-112’s web conguration
page, which consists of ve menu items for future settings.

3. 1 Status

In this page, you will see all the system
status including WAN port status,
IP/MAC address, system uptime and

rmware version.

3. 2 WAN

You can either choose to statically

congure or to dynamically congure

the WAN interface (via a DHCP server
on the network, or via PPP if you are
using PPPoE),

If you wish to statically assign the WAN
interface settings: enter the IP address, the subnet mask, the default gateway
IP address, and the DNS server IP address. It is also recommended that the
network domain name be provided as well, to ensure correct DNS operation.
Press “Apply” to save and apply the new settings.

3.2.2MACspoong

This eld allows the user to set the Ethernet hardware/MAC address to be used
by the WAN interface. This is typically done to mimic (‘spoof’ or ‘clone’) the MAC

address of one of the devices connected to the private LAN interface. To do this,
follow these steps:

1. Enter the 12 digits hardware address to assign to the WAN interface; andEnter the 12 digits hardware address to assign to the WAN interface; and

2. Press the “Apply” button to save and apply the new settings.

3. 3 SIP

3.3.1 SIP proxy server

Enter the SIP server’s address and port

value. The address may either be an IP

address or the server’s name. If you wish

to specify a special SIP domain name,
you may enter the domain name here.
If no domain name is entered, the SIP
domain name will be set to that of the
network (i.e. that which is obtained via

DHCP, or specied on the LAN settings

page).

Select whether or not to send a Registration Request to the SIP server by
assigning a value (in seconds) for the “Registration Expiration”. Enter the line
phone number, the Caller-ID Name, the signaling port value, the authentication
username and the password.

There are two groups of SIP server IP and account data elds for user to enter,
AX-112 will try to register with the rst one and if the rst registration failed, it will
try the second SIP server IP, if you have entered the conguration data. If both

of the SIP servers IP failed to register, you will hear a busy tone when you pick
up the phone-set. Otherwise, you will hear a normal dialing tone if the registration
is successful.

3.3.2 Outbound proxy

If you need to use outbound proxy, assign the outbound proxy server IP and its
port number.

Chapter3-Conguration

3.3.3 NAT traversal setting

Select the NAT traversal type. You may check the uPnP button if your NAT/Firewall
supports uPnP SIP ALG, or assign the STUN server IP if you are using STUN
service. You may also assign the RTP port if there is port enabling on your router
settings.

3.3.4 ToS/DiffServ settings

This sub-page is used to congure the Type-of-Service/Diffserv byte values. These

values are to be used in the IP header of all transmitted SIP signaling packets and
RTP packets. The ToS/DiffServ byte values are entered as a two-digit hexadecimal

value. If no special ToS/DiffServ value is to be used for a particular trafc type,

enter “00” or leave the setting empty.

3. 4 Advanced setting

There are ve sub-pages in the advanced settings page. Basically, this page is for

the advanced users. Most of the time, the default settings should work for normal

application unless your service provider needs special conguration.

3.4.1 CODEC & Packet

English

CODECconguration

Choose which codecs are to be supported. For SIP protocol, the G711U and
G711A protocols are always supported by default. You can select which complex
codec is to be supported in AX-112. But due to memory limitations, it is not possible
to select more than one complex codec at the same time.

You can also select to enable or disable the silent suppression function for each
codec type. To do this, just click on the checkbox beside a codec type.

AX-112 Analog Telephone Adapter 15

Chapter3-Conguration

English

Packetization period

Select the packetization period to be used for each selected CODEC. Each codec
has a different basic packetize period (usually it’s 30ms for G.723, 10ms for G.729).
You can select longer time period to increase the transmission efciency. But,
longer packetization time will cause longer delay time.

3.4.2 DTMF & Gain & Dialling

DTMF

This eld allows conguration of the

DTMF signaling options for SIP. Select
whether the OOB (Out-Of-B and)
telephone event signaling is to be done
using the SIP INFO message; or to be
done via RFC2833 RTP signaling; or
select in band audio which will directly
transmit out the DTMF tone.

Jitter buffer

The Jitter Buffer settings apply to all active CODEC decoders. You may choose

an adaptive jitter buffer or a xed length jitter buffer. For an adaptive jitter buffer,
choose the maximum allowable play out delay (in milliseconds). For a xed jitter
buffer, choose the xed play out delay (in milliseconds). Finally, select whether

or not a decoder should automatically switch from an adaptive jitter buffer to

a xed jitter buffer upon fax/modem tone detection. Adaptive jitter buffers are

sometimes detrimental to fax transmission over G711 CODECs if they have to
adapt too rapidly or too extensively due to inconsistent and widespread packet

delays. In these adverse network conditions, a xed jitter buffer provides superior

performance when handling incoming fax transmissions over G711 CODECs.

Tx/Rx Gain

You can adjust the VoIP voice transmission and receive volume by adding or
decreasing the db value. The adjustable range is from –12db to +18db.

Actually , this is a very wide range for gain adjustment; the default value is 0 db
for both direction. To set the gain too high may cause echo, voice distortion or
DTMF tone will not be able to send the correct errors. Normally, it is reasonable
to make the adjustment between –6db to +6db range.

16 AX-112 Analog Telephone Adapter

Chapter3-Conguration

Phone default connect to

You can select the connection state of the phone set to VoIP FXS codec circuit

or to the PSTN port when the line is idle. It is set to ‘FXS’ by factory default for

normal usage. For one special case, when the caller ID signal from PSTN line

comes before the rst ring, then you may select the phone set to be connected

to PSTN as default and ensure all the caller ID signal pass to the phone set.

When you select the option “Phone default connect to PSTN”, you must make

sure your PSTN line is properly connected to the RJ11 jack of the line port and it is

working properly. If your PSTN line is not working with proper voltage on line, the

phone set will not operate properly.

Dialing plan

A dialing plan gives the unit a map to determine when a complete number has
been entered. Dialing plans are expressed using the same syntax as used by

MGCP NCS specication. The formal syntax of the dialing plan is described by

the following notation:

Digit ::= “0” | “1” | “2” | “3” | “4” | “5” | “6” | “7” | “8” | “9”
Timer ::= “T” | “t”
Letter ::= Digit | Timer | “#” | “*” | “A” | “a” | “B” | “b” | “C” | “c”| “D” | “d”

Range ::= “X” | “x” --matches any digit | “[“ Letters “]” --matches any of the specied

letters
Letters::= Subrange | Subrange Letters

Subrange::= Letter --matches the specied letter | Digit “-” Digit --matches any digit
between rst and last

Position::= Letter | Range
StringElement::= Position --matches any occurrence of the position | Position “.” -­matches an arbitrary number of occurrences including 0
String ::= StringElement | StringElement String
StringList::= String | String “|” StringList
DialPlan::= String | “(“ StringList “)”

English

A dialing plan, according to this syntax, is dened either by a (case insensitive)

string or by a list of strings. Regardless of the above syntax a timer is only allowed
if it appears in the last position in a string (12T3 is not valid). Each string is an
alternate numbering scheme. The unit will process the dialing plan by comparing

the current dial string against the dialing plan, if the result is not qualied (partial

matches at least one entry) then it will do nothing further. If the result matches or

is over-qualied (no further digits could possibly produce a match) then sends

out the string and clear the dial string. The Timer T is activated when it is all that
is required to produce a match. The period of timer T is 4 seconds. For example
a dialing plan of (xxxT|xxxxx) will match immediately if 5 digits are entered, it will
also match after a 4 second pause when 3 digits are entered.

Simple dial plan

Allows dialing of 7 digit numbers (e.g. 5551234) or an operator on 0. Dial plan
is (0T|xxxxxxx) .

Complex dial plan

Local operator on 0, long distance operator on 00, four digit local extension number

starting with 3,4 or 5, seven digit local numbers are prexed by an 8, two digit star
services (e.g. 69), ten digit long distance prexed by 91, and international numbers

starting with 9011+variable number of digits. Dial plan for this is:

(0T|00T|[3-5]xxx|8xxxxxxx|*xx|91xxxxxxxxxx|9011x.T)

Quick dial key

This function lets you to select if you want to use the “#” or “*” key as end of

DTMF input key, it’s useful especially when the dialing number length is not
xed. Pressing the “#” can notify AX-112 to stop waiting any more DTMF input

and sends the numbers out.

For system dialing plan, you may need to send the “#” and “*” key as part of the
dialing number. You may check the buttons to enable or disable this option.

Caller ID type

You can select the AX-112 output caller ID type to t to different phone-set. AX-

112 can show the incoming call ID to your phone set LCD. There are four types
supported that you can choose from. Refer to the list below.

Service code

This sub-page is used to congure the service code. After the service code
has been dened, you can subscribe to a call service by setting it through the
keypad. You must have dened the parameter of these elds before using

relative command by phone set. Click “Apply” to make save and apply the new
settings.

ASUS recommends that you change the service code values only if there is a

conict with the setting of your service provider. Refer to Chapter 4: Operation

for more information.

Chapter3-Conguration

Speed dial & phone book

AX-112 supports eight speed-dial and eight phone book entries for easy call

operation. You may enter the SIP extension number in the speed-dial elds. By
dialing the speed-dial prex code (default is ‘*68n’) dened in the “Service Code”

with the speed dial index number (1~8), AX-112 will send out the call invitation
through the registered SIP server.

The phone book has almost the same function as the speed-dial. The difference
is, it needs a user ID, an IP address, and a port number to send out call invitation.
This means you can not send out call invitation to different IP addresses through
the registered SIP server. Click the “Apply” button to save and apply the new
settings.

Tone

The various tone patterns generated by the AX-112 are all congurable via the
standard conguration variable process. This section describes how to congure

the commonly used tones. The “language” for specifying the tone components is
quite simple. Basically, the language is a combination of frequency, duration and
amplitude and it is known as ABNF. Please refer to the following examples:

Example 1: European dialtone

425Hz @ -5dbm0, tone repeats indenitely. In this case, the value of the ON time (i.e.

1000) is irrelevant, but MUST be greater than zero.

DIALTONE = 425@-5#ON(1000),R

Example 2: US ringback tone

440Hz @ -19dbm0 + 480Hz @ -19dbm0, with the following play out sequence being
repeated indenitely: ON for 2s, OFF for 4s.

RINGBACK = 440@-19+480@-19#ON(2000),OFF(4000),R

Example 3: Custom tone with repeated states.

In this case, a tone of two frequencies (440Hz@-5dbm0 + 1200Hz@-5dbm0) is played

out according to the following timing sequence: ON for 500ms, OFF for 500ms, ON for

500ms, OFF for 500ms, ON for 500ms, OFF for 500ms, ON indenitely (the value of
the last ON is irrelevant, but must be non-zero).

CUSTOM_1 = 440@-5+1200@-5#[ON(500),OFF(500)]3,ON(1000),R

Chapter 5 - Troubleshooting

5. Troubleshooting

5.1 General Troubleshooting

There is no LED activity at power on.

• Check that the power supply unit (PSU) is properly connected.

• Check if the ‘Phone default connect to’ option at ‘Advanced’ setting page. If it
were set to “PSTN’ and your PSTN line is not wired properly (without voltage

presented), then there will be no dialing tone at all. If you have no PSTN line

connected to the AX-112 line port, please set the ‘Phone default connect to’

option to “FXS”.

5.2 Network Troubleshooting

General network activity problems. The device does not appear to be
performing any network related functions.

• For Ethernet devices, make sure that the Ethernet connection is secure, and
the Ethernet cable quality is good.

• Try pinging the device’s IP address from any Unix or Windows machine

connected to the same network.

Input: ping www.xxx.yyy.zzz [Enter]

(where www.xxx.yyy.zzz is the IP address of the unit).

English

The automatic DNS discovery process for a VoIP server does not
appear to work.

• Ensure that the DNS server is capable of servicing DNS TXT or SRV
queries, and that it is configured to respond with the correct server
information when queried.

• If the device is configured via DHCP, ensure that the DHCP server has provided
the correct DNS server and the domain name information.

English

Thedevice’sWebpagesarenotaccessible.

• Try pinging the device’s IP address.

• The unit is trying to acquire a DHCP IP address. Make sure that the Ethernet
cable connection is secure.

• Verify that the DHCP server on the network is functioning.

• If you do not have a DHCP server or want to use a fixed IP address instead,
you need to reconfigure the device to use a static network assignment.

• If the device network information has been statically assigned (i.e. not via
DHCP), ensure that the DNS server IP address is correct, and that the network
domain name has been provided and is correct.

The web browser complains often about errors on the page.

• Ensure that the web browser supports frames and that javascript is enabled.

Although the device’s internal web pages should be accessible from most

modern web browsers, we recommend using Microsoft IE 5.0 (or later version)
or Netscape4.0 (or later version) for optimal results.

TheinterfaceisconguredforPPPoE,butisnotworking.

• If authentication is required, check that the username and password are
correct.

• The PPPoE server may require special Service Name or AC Name tags.
Check with the server if these tags are required and make sure the appropriate
values are configured.
