Section 1

Overview

Panasonic Hybrid IP-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 LAN/WAN environments, seamlessly bridges Public Switched Telephone Network (PSTN) and analogue telephone with digital data networks without interrupting or compromising ongoing data communications. Because communications do not take place over conventional telephone networks, the high cost of long distance communications is virtually eliminated.

Getting Started 5

1.1 Example Network Diagram

1.1 Example Network DiagramThe following diagram illustrates a simple VoIP network connecting Hybrid IP-PBXs at 2 different locations. The VoIP Gateway Card converts outgoing voice or fax signals into IP data 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 Line Service InterfaceQSIG line service allows PBX to support communications with other company members in a private network where the PBX is included. Implementation of VoIP Gateway Cards provides a VoIP interface to employ QSIG line service between Hybrid IP-PBXs at different locations by using IP network instead of conventional telephone networks.

Types of IP NetworkThe VoIP Gateway Card's quality of performance depends on the type of network in use. Manageable networks in which static*1 IP addresses can be used provide better quality of service compared to unmanageable networks such as the Internet, where quality of service is not guaranteed.

FirewallA 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 network through a firewall, refer to "A2 Firewalls" for more details.

1.2.2 Numbering Plan Example

There are 2 methods to plan your numbering system as follows:

This section provides the network numbering mechanism using the PBX Office Code method (see "A1 Numbering Plan Example Alternative" for the example using the Extension Number method) based on the previous example diagram. Configure your network referring to this example.

*1 Dynamic IP addressing (using DHCP/BOOTP) is not supported.

Examples of recommended IP network

• Digital Leased Line

• IP-VPN

• Frame Relay

Not recommended

• Internet(Delays and loss in data transmission can cause degradation in speech quality.)

PBX Office Code method

In addition to the destination number, the caller dials the unique Office Code of the PBX to which the called party is connected. Therefore, each PBX in the network can have the same extension numbering scheme. That is, for example, each PBX in the network can have an extension whose number is 201.

Extension Number method

The caller dials only the destination number of the called party to call through PBXs at different locations (hence there are less digits to dial than with the PBX Office Code method). To employ the Extension Number method, no 2 PBX can have extensions sharing the same number. That is, for example, if 1 PBX in the network has an extension whose number is 201, no other PBX can have an extension with the same number (201).

3.3 Configuring Domain Name System (DNS) Data

3.3 Configuring Domain Name System (DNS) DataThe function of a DNS in a VoIP network is to provide telephone number-to-IP Address translations*1. The VoIP Gateway Card has internal DNS capabilities that can contain a maximum of 511 units in the network. DNS is to be owned jointly by all units in the network. Therefore, whenever the DNS is changed, you must update every unit with the latest DNS; otherwise the VoIP communication cannot be established.

For example numbering plan, refer to "1.2 Network Devices and Numbering Plan".

3.3.1 Creating DNS Data

The MCS permits DNS data to be entered and edited while off-line. Transfer the data over the network to all units only after it is fully configured (instructions will be given in "3.5 Transferring Data to the Units").

*1 IP address-to-telephone number translation can also be handled by using an H.323 Gatekeeper device. To configure Gatekeeper devices, refer to the manufacturer's documentation. This manual focuses on the method using the VoIP Gateway Card internal DNS capabilities.

3.6 Synchronising Time and Date of the UnitsLoss of clock synchronisation of the unit will produce alarm indications under 2 conditions: (1) when the VoIP Gateway Card is newly installed to the Hybrid IP-PBX, or (2) when it has been disconnected from a power source for more than two months, causing the battery discharge. However the alarm indications do not affect the VoIP operations, they should be corrected following the procedure below.

3.6.1 Synchronising Time and Date

When synchronising time and date, the VoIP Gateway Card must be connected to a PC (see "2.2.2 10BASE-T Cable Connection"). The VoIP Gateway Card's time and date will be synchronised with those of the PC with which the card is connected.

1. a. Click the desired units.

b. Click "Unit" "Time sync..." from the menu bar.

2. Confirm the units, and click [Execute].

A2.1 Firewalls

It is generally preferable that a IP Gateway network installation be connected with the IP network outside of any existing firewall installation. When for practical or policy reasons an installation must be routed through a firewall, some performance degradation may occur.

In the above example, the VoIP Gateway Card is routed through a firewall. The Router IP address no longer serves as the VoIP Gateway Card’s Default Gateway IP address. Instead, the internal IP address of firewall becomes the Default Gateway IP address to be associated with the VoIP Gateway Card.

Also, when installing the IP Gateway network within a firewall, voice and fax packets must be routed through specified firewall ports, using the information in the following table:

A3 Optimising Performance

A3 Optimising PerformanceAlthough the features of the VoIP Gateway Card go a long way toward assuring clear voice communications and error free fax transmission over digital data networks, some network conditions can cause performance degradations.

Common causes include:

• Voice PAD settings not correctly configured.

• Many collisions among packets within the Local Area Network (LAN).

• Number of hops packets go through is too large.

• High traffic conditions are prevalent on the network.

• Routing through a firewall.

• Wide Area Network (WAN) transmission delays.

• Internet Service Provider (ISP) has inadequate service characteristics.

The methods used to prevent problems and optimise performance depend on the type and configuration of the network equipment in use. Below are some suggestions that may prove useful.

A3.1 Voice Volume

In some applications, voice volume may be either too low or too high. The gain control feature operates on both the incoming and outgoing sides and is referred to as the PAD control. The VoIP Gateway Card is able to optimise the gain or loss level of the voice signals.

In most cases, it should not be necessary to modify the default PAD In (PAD value of the voice signals coming in to the unit)/PAD Out (PAD value of the voice signals going out from the unit) settings. Indications that some adjustment is required are:

Voice level too low: Increase gain by decreasing PAD level.

Voice loud/distorted: Decrease gain by increasing PAD level.

Excessive background noise: Decrease gain by increasing PAD level.

To configure, refer to "4.9.1 Configure Gateway Units (KX-TDA0480)" in the VoIP Gateway Card Installation Manual.

A3.2 Transmission Delays

Transmission delays can cause pauses and loss in voice communications and may result in delays and loss of fax transmissions. These conditions typically arise when there are high traffic loads (congestion) on the LAN and/or WAN. In the case of the LAN, the network design affects performance. In the case of the WAN, the local router, the link to the ISP (i.e. ISDN, FR, F/T1, and T1), and the Internet Service Provider (ISP) facilities also affect performance.

Transmission delays are caused by excessive packet collisions. The probability that this condition will affect the VoIP Gateway Card performance can be minimised by taking steps to

Getting Started 45


provide the VoIP Gateway Card with clear transmission paths.

VoIP Gateway Card LocationOne preventative measure is to install the VoIP Gateway Card so that the number of transmission hops is kept to a minimum. In the figure below, the VoIP Gateway Card is located as close to the WAN interface as possible.

A3.3 Priority Control

Some routers permit the configuration of priority control features. This allows the router to be configured to give higher priority to packets with high priority flags. The priority control feature should be used when available.


A3.4 Recovery Delay and Jitter Buffer

When voice signals are packetised and transmitted, individual packet can take different paths through the network and arrive at the destination at varied timings (Jitter). The VoIP Gateway Card supports a secondary Jitter Buffer (max. 1920 ms) in which the packets are accumulated temporarily for processing to compensate for network congestion problems.


A3.5 Internet, Intranet, and Virtual Private Networks (VPN)

Manageable networks (e.g., Intranet, Leased Lines, VPN) provide better quality of service compared to unmanageable networks such as the Internet.

When implementing a VoIP network, care must be taken when assessing bandwidth requirements. The VoIP Gateway Card uses 12 kbps per call when in use by default. Serialisation delays to the WAN are lower when higher bandwidths are used.

When using the Internet/VPN, the ISP plays an important role in reducing the variable delay in the WAN. A regional or national ISP will usually have better connectivity with the backbone and will be able to guarantee greater service reliability than a local city ISP. When using VPN facilities, delays may be introduced due to the additional processing time required for encryption processing.
