1.1 Overview
1.1.1 Using IP Proprietary Telephones on a Local Office LAN
Panasonic KX-NT series IP proprietary telephones (IP-PTs) allow voice communication over the data
network by converting the voice into data. The following diagram shows a simple Voice over Internet
Protocol (VoIP) network using the IP-PTs at the local office.
Note
The example illustrations in Sections 1 and 2 use the KX-TDA200 PBX and IP-EXT16 card.
Network Parameters
You will need to have the following IP addressing and VLAN ID information to use IP-PTs on your network.
This information is typically supplied by a network administrator.

Network Parameters
To use IP-PTs at the remote office, you will need to have the IP addressing and VLAN ID information
described in "1.1.1 Using IP Proprietary Telephones on a Local Office LAN".
Types of IP Network
When using IP-PTs over LANs at different locations, first confirm the type of IP network connecting the
LANs. The speech quality depends on the type of IP network in use. Managed IP networks provide better
speech quality compared to unmanaged networks such as the Internet, where quality of service cannot be
guaranteed.
Note
Unlike an IP-VPN, which is set up over a network provider's own IP network, an Internet VPN is set up
over the Internet. Internet VPNs are not recommended for IP-PT communication because transmission
delays and loss of data are likely to occur.

1.2 Network Management
1.2.1 DHCP (Dynamic Host Configuration Protocol) Server
For IP-PTs to communicate over a network, an IP address must be assigned to each IP-PT to identify its
locations on the network. While these addresses can be assigned manually at each IP-PT, it is also possible
to use a DHCP server.
A DHCP server automatically assigns IP addresses to IP-PTs when they are connected to the network. An
IP-PT then uses the received IP address information to register to the IP-EXT card.
Using a DHCP server allows you to centrally manage and automate the assignment of IP addresses.
Notes
• The Hybrid IP-PBX is not able to act as a DHCP server. To use the DHCP client function of IP-PTs,
a separate DHCP server is required on the network, as shown above.
• The IP address for the IP-EXT card cannot be assigned automatically using a DHCP server. This
IP address must be assigned manually by using the Maintenance Console (PC programming
software of the Hybrid IP-PBX). For details, refer to "4.1 Programming the IP-EXT Card".
• An IP-PT cannot request an IP address from a DHCP server on another LAN (connected through
an IP network). An IP-PT can only receive IP address information from a DHCP server on its own
LAN. Therefore, when IP-PTs are located on several LANs, a DHCP server is required on each
LAN. If a DHCP server is not present on the LAN, IP addresses for IP-PTs on that LAN must be
assigned manually.

1.2.2 VLAN (Virtual LAN)
VLANs are logical segments within a corporate LAN. By assigning VLAN settings to IP-PTs, it is possible to
separate the packets transmitted by an IP-PT according to the type of data, and specify which VLAN each
data type will be sent over. This allows you to avoid generating unnecessary network traffic on each
segment, and to reduce the load on the network. As a consequence, speech quality can be assured.
Therefore, we recommend using the VLAN feature to perform VoIP communication effectively.
Some IP-PTs (e.g., KX-NT136) are equipped with 2 ports, primary and secondary, for packet
communication. Allocating these ports to different VLANs enables you to split the paths for packets
depending on whether the packet contains voice signals or data.
VLAN settings (VLAN ID and VLAN priority) for the primary port affect voice data transmitted by the IP-PT,
whereas VLAN settings for the secondary port apply to data transmitted by a PC connected to the IP-PT.
When sending packets, the IP-PT can attach information on which VLAN the packets are to be transmitted
over (VLAN Tagging). The switching hub that receives these packets reads the VLAN information and sends
the packets over the appropriate VLAN. This helps to ensure bandwidth for IP-PT voice transmissions.
In this way, an IP-PT with 2 ports can transmit voice packets from the primary port with higher priority than
other packets from the secondary port.
Notes
• This VLAN feature complies with IEEE (Institute of Electrical and Electronics Engineers) 802.1Q.

1.2 Network Management
10 Information about IP Proprietary Telephones
• The Hybrid IP-PBX receives VLAN settings only from the connected switching hub. Therefore,
VLAN settings for the Hybrid IP-PBX must be assigned at the switching hub.
• Some PC LAN cards allow VLAN settings to be assigned. However, when using a PC connected
to an IP-PT with 2 ports, the VLAN settings for PC communications must be assigned only to the
secondary port of the IP-PT. Any VLAN settings assigned to the PC LAN card must be disabled.
These settings can usually be identified by "802.1Q", "802.1p", or "VLAN" in their name.
• If you are using an IP-PT with a primary port only (e.g., KX-NT265), a PC cannot be connected to
the IP-PT.

Guidance for VoIP Installation

2.1 VoIP Requirements
12 Information about IP Proprietary Telephones
2.1 VoIP Requirements
2.1.1 Bandwidth Assessment
When using IP-PTs, 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 the network
can accommodate, speech quality will be compromised. In addition, there may be an 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.
Required Bandwidth per IP-PT for a Call
The required bandwidth depends on what combination of CODECs and packet sending intervals is used.
Keep in mind the following points about the type of CODEC and packet sending interval, in terms of speech
quality:
• The speech quality of the G.711 CODEC is higher than that of the G.729a CODEC.
• The shorter the packet sending interval, the higher the speech quality.
• The higher the speech quality the IP-PTs provide, the more bandwidth the IP-PTs require.
Required Bandwidth for Each IP-EXT Card
To allow all IP-PTs to make calls simultaneously, it is necessary to keep available the bandwidth required
by an IP-EXT card with the maximum number of IP-PTs connected.
Provided below is the formula to calculate the amount of bandwidth required for each card.
2.1.2 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 evaluated.
Is the IP network a managed network?
A VoIP network should be implemented on a managed IP network such as Frame Relay, Leased Line, or
IP-VPN (Virtual Private Network).
CODEC Packet Sending Interval
20 ms 30 ms 40 ms 60 ms
G.711 87.2 kbps 79.5 kbps — —
G.729a 31.2 kbps 23.5 kbps 19.6 kbps 15.7 kbps
When using the IP-EXT4 card:
Required Bandwidth = (Required Bandwidth per IP-PT × 4)
When using the IP-EXT16 card:
Required Bandwidth = (Required Bandwidth per IP-PT × 16)

2.1 VoIP Requirements
Information about IP Proprietary Telephones 13
An unmanaged network, such as the Internet (including an Internet VPN), cannot be used to employ a VoIP
network because delays and loss in data transmission can cause huge degradation in speech quality.
Is it possible to have static IP addressing?
IP-PTs on the network must always communicate with each other through the IP-EXT card, not directly.
Therefore, the card must be assigned a static IP address, which must be programmed to each IP-PT on the
network.
Note
When a DHCP server (which automates IP addressing of the IP-PTs on the network) is not used, static
IP addressing must also be enabled for all IP-PTs.
Does only a single router provide IP-PT access to the IP network?
In a dual network, 2 routers provide access to the IP network as shown in the diagram below. However, only
one router can be used as an access point to the network for all IP-PTs.
Therefore, in the diagram below, if router A, whose IP address is assigned as the default gateway IP address
of the IP-PT and IP-EXT card, fails, VoIP communications are no longer possible; they are not able to switch
their default gateway from router A to router B to access the IP network.

14 Information about IP Proprietary Telephones
Does the router not use network address translation (NAT/NAPT)?
If the router uses address translation techniques (e.g., NAT/NAPT) to convert between global and local IP
addresses, VoIP communications between the IP-EXT card and IP-PT cannot be carried out effectively.
Therefore, the routers used to access the IP network must not use NAT/NAPT. Generally, NAT and NAPT
are features that are available with routers.

2.1 VoIP Requirements
Information about IP Proprietary Telephones 15
Are the IP-EXT card and IP-PTs located appropriately?
Transmission delays can cause pauses and loss in VoIP communications. The more routers there are
between the IP-EXT card and IP-PTs, the longer the transmission delays. This is because a certain amount
of delay is inevitable when packets pass through each router.
Additionally, the more switching hubs between the card and IP-PTs, the longer the transmission delays,
because the switching hubs must also handle the network traffic generated by other terminal devices (e.g.,
PCs) connected to them.
To prevent unnecessary delays, it is recommended to connect the card and IP-PTs so that there are as few
network devices (e.g., routers, switching hubs) between them as possible.
2.1.3 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 evaluated.
Can the firewall pass packets from IP-PTs?
If the VoIP network contains a firewall, the firewall must be configured appropriately to allow VoIP packets,
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 3 switches used?
Use of repeater hubs can increase the network load, and therefore may result in degradation in speech
quality.
To ensure high speech quality, use only layer 2 or 3 switches when connecting the IP-EXT card to the LAN.
Use of layer 2 or 3 switches is also strongly recommended for connecting IP-PTs.
Note
Note that the port of the switching hub that connects to the IP-EXT card should be set to operate under
"Auto Negotiation" mode.
