Section 1 Overview Panasonic PBX with VoIP Gateway Card will allow organizations 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 analog telephones with digital data networks without interrupting pre-existing data communications.
1.1 Example Network Diagram 1.1 Example Network Diagram The following diagram illustrates a simple VoIP network connecting PBXs at two 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. PSTN (Public Switched Telephone Network) Switching Hub Voice signals are converted into IP packets.
1.2 Network Devices and Numbering Plan 1.2 Network Devices and Numbering Plan You will need to have network configuration information available to install VoIP Gateway Cards. Referring to this example diagram, consult your network administrator to obtain necessary information to configure your own VoIP network. Extn. 201 (200-299) Local Telephone 456-7890 G3 Fax Extn. 501 (500-599) PSTN (Public Switched Telephone Network) Subnet Mask: 255.255.255.0 Card IP: 200.45.11.
1.2 Network Devices and Numbering Plan 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.
1.2 Network Devices and Numbering Plan Note An example using the extension number method is provided in "B Alternative Numbering Plan Example". IP Addressing Information IP addressing information is typically supplied by a network administrator. Consult your network administrator for specific values.

A1 VoIP Requirements A1 VoIP Requirements A1.1 Bandwidth Assessment To establish a VoIP network, you must ensure that the network has enough bandwidth to support VoIP communications. 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.
A1 VoIP Requirements Required Bandwidth for Fax Communication Via LAN G.711 Packet Sending Interval FAX High Reliable Method 20 ms 30 ms 40 ms Don’t Use 87.2 kbps 79.5 kbps 75.6 kbps Use 224.8 kbps 213.9 kbps 208.4 kbps Via WAN (PPP: Point-to-Point Protocol) G.711 Packet Sending Interval FAX High Reliable Method 20 ms 30 ms 40 ms Don’t Use 84 kbps 77.3 kbps 74 kbps Use 221.6 kbps 211.7 kbps 206.8 kbps Example Consider the following case as an example: • Communication: via LAN • No.
A1 VoIP Requirements 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.
A1 VoIP Requirements Does only a single router provide access to the IP network? In a dual network, two routers provide access to the IP network as shown in the diagram below. However, the VoIP Gateway Card cannot take the advantage of having two routers as access points to the IP network.
A1 VoIP Requirements Is there only a single IP network between two 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.
A1 VoIP Requirements 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.
A1 VoIP Requirements *2 For the actual setting values, refer to "2.2.1 Network Parameters" in the VoIP Gateway Card Programming Guide. Are layer 2 or higher switches used? Use of repeater hubs can increase the network load, and therefore may result in degradation in speech quality. To ensure the performance, it is strongly recommended that you use layer 2 or higher switches. Are category 5 (CAT 5) cables used? When connecting network devices, make sure to use CAT 5 cables.
A2 VoIP Requirements Checklist A2 VoIP Requirements Checklist Use the following checklists to see if you can implement a VoIP network. The answers identified in underlined bold-face letters are the required answers for the corresponding questions. Bandwidth Assessment No. Question 1 Does the network have enough bandwidth to support VoIP communications? Make sure that there is more bandwidth available for VoIP communications than the amount actually required. Answer Memo • Yes • No • Ref.
A2 VoIP Requirements Checklist Network Devices No. Question 3-a Can the firewall pass packets from the VoIP Gateway Card? When a firewall is used, make sure to configure the firewall appropriately to allow VoIP packets to pass through the network without being blocked by filtering. 3-b 3-c Are layer 2 or higher switches used? Do not use repeater hubs as they can increase the network load. Are category 5 (CAT 5) cables used? Answer Memo Ref. Model of the firewall: Yes p.
