  2. Start up of IP-PT – CASE 1 Lost! Lost! Lost! Lost! Lost! Lost! Lost! PTAP (Start Request) PTAP (Start Request) PTAP (Start Request) PTAP (Start Request) PTAP (Start Request) PTAP (Start Request) PTAP (Start Request) 4sec 500ms 4sec 1sec 2sec 4sec Port 9301 Port 9301 Port 9301 Port 9301 Port 9301 Port 9301 Port 9301 Port 9300 Port 9300 Port 9300 Port 9300 Port 9300 Port 9300 Port 9300 CASE1: If the packet of PTAP is lost in the network… IP-PT DHCP IPEXT16 LCD Display Message Any Mode IPL Starting … Now loading SRC:0.0.0.0: port 68 DST:255.255.255.255: port 67 Searching … port68 port67 DHCP discover This process works only when you program DHCP=Enable port68 port67 DHCP response Searching …. 40sec POOR LAN CONNECTION If the response for Start Request does not come from IPEXT16, IP-PT continues the resending process of Start Request for 40sec totally. If still no response, “POOR LAN CONNECTION” is shown. CONFICENTIAL

  3. Start up of IP-PT – CASE 2 Then IPEXT16 rejects it. CASE2: If new IP-PT before the registration is Started-up… IP-PT DHCP IPEXT16 LCD Display Message Operation Mode IPL Starting … Now loading SRC:0.0.0.0: port 68 DST:255.255.255.255: port 67 This process works only when you program DHCP=Enable Searching … port68 port67 DHCP discover port68 port67 DHCP response PTAP (Start Request) Port 9301 Port 9300 Is MAC address registered? (“MAC Address”, “IP Address”, “Model Code” etc.) Searching …. It’s not registered. PTAP (NAK) Port 9301 Port 9300 UNREGISTERED TO SERVER When IP-PT (that wa not registered) start-up, IP-PT sends Start Request by PTAP. But IP-EXT16 rejects it after checking the registration of MAC Address of IP-PT. CONFICENTIAL

  4. Start up of IP-PT – CASE 3 CASE3: If new IP-PT is started up in the registration mode of IP-EXT16… LCD Display Message IP-PT DHCP IPEXT16 IPL Starting … SRC:0.0.0.0: port 68 DST:255.255.255.255: port 67 Registration Mode Now loading port68 port67 DHCP discover Searching … port68 port67 DHCP response Is MAC address registered? PTAP (Start Request) Port 9301 Port 9300 Searching …. PTAP (ACK) New MAC is registered. Port 9301 Port 9300 (transmitting resending interval of PTAP etc.) * If it’s not registered, IP-EXT16 understands as new registration of IP-PT in this mode. Registration OK! Server Connecting… MGCP call control process PTAP (Alive Check) Port 9301 Port 9300 * Every programmed periods, Alive Check process is inserted in the MGCP process. Alive Check PTAP (ACK) Port 9301 Port 9300 MGCP If IP-PT sends Start Request in the registration mode of IPEXT16, and if the MAC address of IP-PT is not registered, IPEXT16 registers it as new IP-PT. CONFICENTIAL

  5. Start up of IP-PT – CASE 4 CASE4: If the registered IP-PT is started up… LCD Display Message IP-PT DHCP IPEXT16 IPL Starting … SRC:0.0.0.0: port 68 DST:255.255.255.255: port 67 Operation Mode Now loading DHCP discover Searching … DHCP response Is MAC address registered? PTAP (Start Request) Port 9301 Port 9300 Searching …. (MAC address, IP address, Model Code, etc.) PTAP (ACK) New MAC is registered. Port 9301 Port 9300 Start OK! (transmitting resending inteval of PTAP, etc.) * If it’s registered, IP-EXT16 understands as re-connection of registered IP-PT. Server Connecting… MGCP call control process PTAP (Alive Check) Port 9301 Port 9300 * Every programmed periods, Alive Check process is inserted in the MGCP process. Alive Check PTAP (ACK) Port 9301 Port 9300 MGCP In the normal mode of IPEXT16, the Start Request from the registered IP-PT is responded by ACK. And please note that the IP address of IP-PT is always informed by Start Request. By this information, IPEXT16 does not necessary to re-register the IP-PT, even if the IP address is changed by DHCP. CONFICENTIAL

  6. Default Port Number Protocol Description TCP/UDP Default Port Number RTP (IP-EXT16) Real-time Transport Protocol. Used for voice data transmission. UDP 8000 to 8063 RTP (IP-PT) UDP 8000 to 8063 Maintenance (IP-EXT16) Panasonic proprietary protocol. Used for communication parameter negotiation with the PBX, download of country/area data, confirmation of connection with the PBX, and notification of error messages and statistical information to the PBX. UDP 9300 Maintenance (IP-PT) UDP 9301 MGCP (IP-EXT16) Media Gateway Control Protocol. Used for call control command data and LCD/LED data transmission. UDP 2727 MGCP (IP-PT) UDP 2747 DHCP Dynamic Host Configuration Protocol. Used for receiving an IP address from a DHCP server. UDP 67, 68 FTP (Port mode) File Transfer Protocol. Used for receiving a data file from a FTP server to upgrade the firmware version. UDP 20, 21 CONFICENTIAL
