Section 1
Overview
Panasonic PBX with VoIP Gateway Card will allow
organisations to route both voice and fax communications
over digital data networks.
The VoIP Gateway Card, designed to be easily integrated into
existing IP networks, seamlessly bridges Public Switched
Telephone Network (PSTN) and analogue telephones with
digital data networks without interrupting pre-existing data
communications. Because communications do not take place
over conventional telephone networks, the high cost of long
distance communications is virtually eliminated.

1.1 Example Network Diagram
1.1 Example Network Diagram
The following diagram illustrates a simple VoIP network connecting PBXs at 2 locations. The VoIP
Gateway Card converts outgoing voice or fax signals into IP packets for transmission. On the
incoming side, it reverses this process and translates the packets back into appropriate voice or fax
signals.

1.2.1 Network Application
QSIG Network Interface
QSIG is a protocol based on ISDN (Q.931) that offers enhanced PBX features in a private network.
The QSIG network supports private communications by the TIE line service method. Implementation
of VoIP Gateway Cards provides a VoIP interface to employ a QSIG network between PBXs at
different locations by using an IP network instead of conventional telephone networks.
Types of IP Network
The VoIP Gateway Card's quality of performance depends on the type of IP network in use. Managed
IP networks provide better quality of service compared to unmanaged networks, where quality of
service is not guaranteed.
Examples of recommended IP networks
• Digital Leased Line
• IP-VPN (Virtual Private Network)
•Frame Relay
Notice
The performance of the VoIP Gateway Card may deteriorate when it is used on the Internet.
Delays and loss in data transmission can degrade speech quality, and impair the card's capability
to use the enhanced networking features of the PBX (for more information about these features,
refer to the relevant sections of the Hybrid IP-PBX documentation.)
Firewall
A firewall protects the internal networks of an organisation against unauthorised penetration from
outside. When routing a VoIP network through a firewall, some performance degradation may result.
If for practical reasons you must route the VoIP network through a firewall, refer to "A1.3 Network
Devices" for more details.
Using the KX-TDA0490 with Other KX-TDA Series VoIP Gateway Cards
When using the KX-TDA0490 in a network that contains other KX-TDA series VoIP Gateway Cards,
keep in mind the following points:
1. Making and Receiving Calls
Calls can be made and received between the KX-TDA0490 and other KX-TDA series VoIP
Gateway Cards. However, the KX-TDA0480 requires a special setting to be able to communicate
with the KX-TDA0490 on the network. Refer to "D1 Considerations in Installation" for more
details.
2. Using QSIG Services
All QSIG services available with the PBX can be used between the KX-TDA0490 and KXTDA0484/KX-TDA3480. However, CLIP service is the only available QSIG service between the
KX-TDA0490 and KX-TDA0480.

1.2.2 Numbering Plan Example
There are 2 methods to plan your numbering system, as follows:
In addition to the destination number, the caller dials the unique PBX code of the
PBX code
method
Extension
number method
This section provides a network numbering mechanism using the PBX code method based on the
previous example diagram. Configure your network referring to this example.
Note
An example using the extension number method is provided in "B Alternative Numbering Plan
Example".
PBX to which the called party is connected. Therefore, extension numbers at
separate PBXs in the network can overlap. For example, each PBX in the
network can have an extension whose number is 201.
The caller dials only the destination number of the called party to call through
PBXs at different locations (hence there are fewer digits to dial than with the PBX
code method). To employ the extension number method, no 2 PBXs can have
extensions sharing the same number. For example, if one PBX in the network
has an extension whose number is 201, no other PBX can have an extension
with the same number (201).

3.2.5 Programming the Address Translation Table
The function of an address translation table in a VoIP network is to provide 2-way translation of
telephone numbers and IP addresses
Gateway Cards in the network. Therefore, whenever the address translation table is changed, it is
important to update all the cards in the network with the latest information; otherwise VoIP
communications cannot be established.
It is possible, at one location in the network, to programme the address translation table that contains
information for the entire network. The completed address translation table can then be distributed
across the network, so that all the cards share the same information (see "3.2.6 Downloading the
Address Translation Table from the VoIP Gateway Card", and "Uploading Address Translation Table
to the VoIP Gateway Card" in "3.3 Programming the VoIP Gateway Card in the Chicago Office").
Note
The address translation table created for the KX-TDA0490 can be shared with the KX-TDA0484
and KX-TDA3480.
The procedure below demonstrates the process of programming the address translation table
necessary for VoIP communications between the Los Angeles and Chicago offices.

A1 VoIP Requirements
A1.1 Bandwidth Assessment
When using the VoIP Gateway Card, you must ensure that the IP network in use has enough
bandwidth to support VoIP communications. If the amount of bandwidth required for VoIP
communications is larger than what the network can accommodate, speech quality will be
compromised. In addition, there may be some adverse effect on the performance of other applications
(e.g., email or web applications) that use the same network. Therefore, care must be taken when
assessing bandwidth requirements.
Inform your network administrator of the required bandwidth, and make sure that the network can
support VoIP communications even under conditions of maximum network traffic.
Bandwidth Calculation
Provided below is the formula to find out the amount of bandwidth required for VoIP communications:
Required Bandwidth
= (No. of Fax Machines × Required Bandwidth for the G.711 CODEC) +
[(16 - No. of Fax Machines) × Required Bandwidth for Voice Communication]
Required bandwidth for one VoIP channel is shown in the tables below (for more details, refer to "2.2.3
Voice Communication Parameters" in the VoIP Gateway Card Programming Guide).
Required Bandwidth for One VoIP Channel
The required bandwidth depends on what combination of CODEC and packet sending interval is
used. Keep in mind the following points about the type of CODEC and packet sending interval, in
terms of the speech quality:
• The speech quality of the CODECs varies as follows: (High) G.711, G.729A, G.723.1 (Low)
• The shorter the packet sending interval, the higher the speech quality.
• The higher the speech quality the VoIP Gateway Card provides, the more bandwidth the
card requires.
Via LAN
CODEC
20 ms 30 ms 40 ms 60 ms 90 ms
G.711 87.2 kbps 79.5 kbps 75.6 kbps 71.7 kbps —
G.729A 31.2 kbps 23.5 kbps 19.6 kbps 15.7 kbps —
G.723.1 5.3 kbps — 20.8 kbps — 13.1 kbps 10.5 kbps
G.723.1 6.3 kbps — 21.9 kbps — 14.1 kbps 11.6 kbps
Packet Sending Interval

Page 47
Via WAN (PPP: Point-to-Point Protocol)
A1 VoIP Requirements
Example
CODEC
Packet Sending Interval
20 ms 30 ms 40 ms 60 ms 90 ms
G.711 84 kbps 77.3 kbps 74 kbps 70.7 kbps —
G.729A 28 kbps 21 kbps 18 kbps 14.7 kbps —
G.723.1 5.3 kbps — 18.7 kbps — 12 kbps 9.8 kbps
G.723.1 6.3 kbps — 19.7 kbps — 13.1 kbps 10.8 kbps
Consider the following case as an example:
• Communication: via LAN
• No. of Fax Machines: 2
• G.711 Packet Sending Interval: 20 ms (requiring 87.2 kbps per channel)
• G.729A Packet Sending Interval for Voice Communication: 20 ms (requiring 31.2 kbps per
channel)
In this case, the required bandwidth will be as follows:
Required Bandwidth
= (2 × 87.2) + [(16 - 2) × 31.2]
= 611.2 (kbps)
Therefore, inform your network administrator and make sure that the network can support a
bandwidth of 611.2 kbps even when the network is under conditions of maximum traffic.
Note
It is recommended that all cards in a VoIP network have the same packet sending interval.
Additional Information
As described above, it is possible to control the required bandwidth by selecting a certain combination
of CODEC and packet sending interval. However, it is also possible to control required bandwidth by
limiting the number of available VoIP channels.
The card supports a total of 8 ports, each having 2 separate channels. By disabling some of the ports,
you can reduce the bandwidth required for VoIP communications.
Getting Started 47
Page 48
A1 VoIP Requirements
To limit the number of VoIP channels:
• Set the status of the ports you wish to disable (starting from the highest-numbered port) to OUS.
For example, if you wish to use only 10 of the available 16 VoIP channels (i.e., disable 6
channels), set the ports 8, 7, and 6 to OUS as shown below:
In this case, the equation for bandwidth calculation, based on the previous example, will be changed
as follows:
Required Bandwidth
= (No. of Fax Machines × Required Bandwidth for the G.711 CODEC) +
- No. of Fax Machines) × Required Bandwidth for Voice Communication]
[(10
= (2 × 87.2) + [(10
= 424 (kbps)
- 2) × 31.2]
A1.2 Network Configuration
You must evaluate the structure of the existing network to see if a VoIP network can be implemented.
Below are the points that should be taken into your evaluation.
Is it possible to have static IP addressing?
Because the maintenance of the VoIP Gateway Card is carried out from a personal computer (PC)
through an IP network, the card must be assigned a static IP address.
Static IP addressing must be made possible even when the DHCP feature is used. For more details,
refer to "2.2.1 Network Parameters" in the VoIP Gateway Card Programming Guide.
48 Getting Started
Page 49
Is network address translation (NAT/NAPT) disabled?
In a network where address translation techniques (e.g., NAT/NAPT) are used to convert between
global and local IP addresses, VoIP communications based on the H.323 protocol cannot be carried
out appropriately. Generally, NAT/NAPT are features that are available with routers.
IP Network
Global IP Address Domain
A1 VoIP Requirements
(NAT/NAPT enabled)
Router
Local IP Address Domain
Note
If the router on the network supports the "H.323 NAT" feature, it may be possible to have VoIP
communications over the network. For more information, consult your network administrator.
Does only a single router provide access to the IP network?
In a dual network, 2 routers provide access to the IP network as shown in the diagram below.
However, the VoIP Gateway Card cannot take the advantage of having 2 routers as access points to
the IP network.
For example, if router A, whose IP address is assigned as the default gateway IP address of the card,
fails, VoIP communications are no longer possible; the card is not able to switch its default gateway
from router A to router B to access the IP network. For more details about the default gateway setting,
refer to "2.2.1 Network Parameters" of the VoIP Gateway Card Programming Guide.

A1 VoIP Requirements
Is there only a single IP network between 2 ends of a call?
A huge degradation in speech quality will be produced when calls are made through multiple IP
networks as shown below; therefore, it is recommended that you avoid establishing a VoIP network
in this fashion.

50 Getting Started
Page 51
Is the card located appropriately?
Transmission delays can cause pauses and loss in VoIP communications. The more network devices
(e.g., routers and switches) there are between the communicating cards, the larger the transmission
delays, because a certain amount of delay is inevitable when packets go through each network device
(hop).
One preventative measure is to install the card so that the number of transmission hops is kept to a
minimum. In the diagram below, the card is located as close to the IP network interface as possible.

A1.3 Network Devices
You must evaluate the network devices that are used in the existing network to see if a VoIP network
can be implemented. Below are the points that should be taken into your evaluation.
Can the firewall pass packets from the VoIP Gateway Card?
If the VoIP network contains a firewall, the firewall must be configured appropriately to allow VoIP
packets, which are listed in the table below, to pass through the network without being blocked by
filtering.
For more information, consult your network administrator.

Are layer 2 or higher switches used?
Use of repeater hubs can increase the network load, and therefore will result in degradation in speech
quality.
To ensure high speech quality, use only layer 2 or higher switches.
Note
Also note that the port of the switch that connects to the card should be set to operate under
"Auto Negotiation" mode. This will help assure error-free communication between the card and
the switch.
Are Category 5 (CAT5) cables used?
When connecting network devices, make sure to use CAT5 cables. If other types of cables are used,
communications may not be carried out normally.
A1.4 QoS (Quality of Service)
Some routers permit the configuration of priority control features. This allows the router to give higher
priority to voice packets and lower the rate of loss and delays during transmissions, hence improving
speech quality. It is strongly recommended that you use this feature, especially in networks where
traffic is heavy.
Typically, a router identifies what packets to pass in priority by checking the value in the ToS field of
the header of IP packets. The VoIP Gateway Card has the ability to set the ToS field of outgoing voice
packets (see "2.2.3 Voice Communication Parameters" in the VoIP Gateway Card Programming
Guide). When the card is appropriately configured, the router can give voice packets from the card
higher priority.
Consult your network administrator when setting the ToS field, as the setting value must conform to
the router's specifications.
Note
Some switches also permit the configuration of priority control features. For more information,
consult your network administrator.

B2 Programming for the Extension Number
Method
When programming the VoIP Gateway Cards and PBXs for use in a network configured for the
extension number method instead of the PBX code method, some of the steps in the programming
procedures require different setting values.
The following 2 sections provide specific steps that require different setting values. The steps other
than those provided here have common setting values, and are therefore omitted from this
explanation.
B2.1 Programming the VoIP Gateway Card
The hunt patterns and address translation table need different setting values for the extension
number method, as shown in the screen shots provided below.
Programming the VoIP Gateway Card in the Los Angeles Office
Create hunt patterns with the setting values shown below, following the procedure in "3.2.4 Assigning
the Hunt Pattern".

B2.2 Programming the PBX in the Los Angeles Office
The steps below are provided in substitution for steps 6 and 7 of the procedure detailed in "4.1
Programming the PBX in the Los Angeles Office". Programme the PBX in the Los Angeles office
using the extension number method, following these steps.
After programming the PBX in the Los Angeles office, follow the same procedure to programme the
PBX in the Chicago office with the appropriate setting values.
Step 6
Assign the PSTN trunk access number:
In the Idle Line Access (Local Access) box, type 92 (for Los Angeles office PSTN access).
Step 7
Assign the leading number used to reach the extensions of the remote PBX:
In the Other PBX Extension Numbering (TIE) box (01 and 02), type 3 (for the Chicago office
extensions) and 6 (for the Chicago office fax extensions).

Step 8
Assign the routing information to route calls to the remote PBX:
In the Leading Number box, type 3 (for the Chicago office extensions), 6 (for the Chicago office fax
extensions), and 93 (for Chicago office PSTN access).
Note
Do not set any value in the Own PBX Code box.

Provided below are the points to consider when the VoIP network contains both the KX-TDA0490 and
KX-TDA0480 VoIP Gateway Cards.
Adding the KX-TDA0490 to the Network Using the KX-TDA0480 Maintenance Console
Software
For the KX-TDA0480 to recognise the KX-TDA0490 in the network, you must add it as an "Other Unit"
in a Unit Group (network) when programming with the MCS as shown below:
Note
For programming instructions and other information about the KX-TDA0480, refer to the
documentation for the KX-TDA0480.
Restrictions on Feature Compatibility
Some restrictions exist when using the KX-TDA0490 with the KX-TDA0480, as detailed below:
• CLIP service is the only QSIG service available between the KX-TDA0490 and KXTDA0480. There is no compatibility for other QSIG services.
• Fax communications cannot take place between the KX-TDA0490 and KX-TDA0480.

Detailed Explanations
Gatekeeper
The following are the general functions of a gatekeeper:
• Dialled number-to-IP address translation
• Authentication
• Bandwidth control
It is possible to employ a VoIP network without the use of a gatekeeper, because the card is equipped
with internal address translation capabilities. However, should the network contain dozens of cards,
maintenance of address translation tables in individual cards can become a strain.
A gatekeeper is useful in this case, because with the gatekeeper it is possible to consolidate the
maintenance. (However, you still need to programme each card on the network with its own address
translation information. For details, refer to "2.2.6 Address Translation Table—GW Entry" and "2.2.7
Address Translation Table—DN2IP Entry".) For more information about gatekeeper functions, consult
the documentation of the gatekeeper.
When using a gatekeeper, make sure to choose a compatible model. For more information about
gatekeeper compatibility with the card, consult a certified dealer.

Jitter Buffer Settings
When voice signals are packetised and transmitted, individual packets can take different paths through the
network and arrive at the destination at varied timings. This is referred to as "jitter", and it can cause
degradation in speech quality. To compensate for jitter problems, the "jitter buffer" accumulates the packets
temporarily for processing.
The parameters below are used to adjust the size of the jitter buffer. However, in general, there is no need to
change the default values.

Echo Canceller Settings
Parameter & Description Default Value Range
Echo Canceller
Specifies the length of the echo canceller (in milliseconds)
when using the echo cancellation feature (G.168), or disables
the feature.
Echo is the audible duplication of a caller's voice on the return
path; when echo exists, the caller hears his or her own voice
after some delay. The echo canceller eliminates this echo.
Generally, the default length of 48 ms will suffice. However, if
an echo is still heard, it is recommended that you set the
length to 128 ms.
Note
There are various factors that may cause an echo. In
some cases, this feature does not eliminate the echo
entirely.

Voice Activity Detection (VAD) Settings
Parameter & Description Default Value Range
G.723.1/G.729A/G.711 VAD
Specifies the use of the VAD feature for each available
CODEC (G.723.1, G.729A, and G.711).
The VAD conserves bandwidth by detecting silent periods
during a call and suppressing the packets of silence from
being sent to the network.
Notes
• To use the VAD feature for a certain CODEC, be
sure to enable it for that CODEC on both the local
and remote cards.
• To use the VAD feature between the KX-TDA0490
and KX-TDA3480/KX-TDA0484, you must enable it
for the G.723.1 CODEC. Otherwise, the VAD feature
cannot be used between these cards (although calls
can be made and received as normal).

G.723.1 6.3 kbps — 19.7 kbps — 13.1 kbps 10.8 kbps
When assessing your bandwidth requirements, keep in mind that the longer the packet sending
interval, the smaller the amount of required bandwidth, and vice versa.
However, also consider that the shorter the packet sending interval, the clearer the expected speech
quality, because delays in packet transmissions will be small. When the packet sending interval is
long, delays are more likely to occur, resulting in overall degradation in speech quality with more
pauses and loss in voice communications.
Therefore, it is recommended that you select the shortest packet sending interval that network
bandwidth can accommodate.
DTMF Detection
A VoIP network does not guarantee accurate end-to-end transmission of DTMF signals because the
DTMF signals are coded/decoded during VoIP communications, in the same way as voice signals. In
addition, packets can get lost during transmission.
To compensate for this problem, it is possible to enable DTMF detection for the VoIP Gateway Card
to carry out accurate end-to-end DTMF relay over the network. Upon detecting DTMF signals from
the PBX, the card encodes the signals and then sends them to the destination, instead of as voice
signals. Then at the destination, the card regenerates the DTMF signals from the received encoded
signals, and then sends them to the PBX.
Note that when this feature is enabled, the sending of packets is delayed by approximately 30 ms.
Therefore, it is recommended that you disable this feature unless DTMF detection is necessary.
CODEC
Packet Sending Interval

FAX Signal Detection
When sending fax signals using a CODEC other than G.711, the signals cannot be received
accurately at the destination because they are coded/decoded over the VoIP network, in the same
way as voice signals.
To compensate for this problem, it is possible to enable fax detection for the card. Upon detecting fax
signals (CED tones) from the PBX, the card automatically switches the CODEC to G.711 to
communicate with the card at the destination. With the G.711 CODEC, it is possible to assure errorfree fax communications to a certain extent.
To further assure fax communications, it is strongly recommended that the communicating fax
machines be equipped with the ECM (Error Correction Model) feature, an automatic error correction
feature. When, for example, the receiving fax machine detects errors in transmission, it can have the
sending fax machine resend the relevant data.
When using the fax detection feature, the communicating cards must share the same value (either
"G.711Mu" or "G.711A") for the parameter Voice CODEC Priority (see "Voice CODEC Settings" in
"2.2.2 H.323 Parameters").
Notes
