Interface Explanation DC Power External DC Power Supply Input. (DC 5V) Interface Explanation DC Power External DC Power Supply Input. (DC 5V) STOP Ensure the AP200 VoIP Gateway is in a dust-free environment before and after installation. If a static prevention waist strap is available, strap it around the wrist and earth the cord before operating the equipment. The console terminal should be configured as: 9,600 Baud, No Parity, 8Bits Data, One(1) Stop Bit. The VoiceFinder AP200 Gateway is set to operate with the configurations above. Therefore, these settings are required for communication between the Gateway and the console terminal.

The DHCP function provides following benefits. Define the DHCP-list type to use in the Gateway. Create a DHCP-list defining DHCP-list number, DHCP mode to use in the Gateway, or DHCP address pool. The domain name and the IP address are given together to DHCP clients. Also, to manage networks, the VoiceFinder AP200 Gateway supports Bridge MIB that is defined in RFC 1286. The bridge functions that the VoiceFinder AP200 Gateway supports are as follows: Complying with IEEE 802.1D standard. If the interface using the bridge is frame-relay, this command sets the map in a way that the bridge maps can be sent through this interface. The default value is 30 seconds. Address type status Port 1111.1111.1111 static bppu0 FFFF.FFFF.FFFF static our mac AA11.0000.1111. Elements configuring an SNMP system to manage the network include the SNMP Manager, the SNMP Agent and the Management Information Base (MIB.) According to the request of the SNMP Manager, the SNMP Agent gives or sets these data. However, if the SNMP Agent sends information without receiving any request from the SNMP Manager, it is called “Trap.”. Set a SNMP community. Set the host to receive SNMP trap. Set SNMP related parameters. Moves to the IP configuration mode. Apply the queue-group that has been set to the corresponding serial interface. The AP200 Gateway provides “show” commands, “Debug” commands and “logging” commands for fault handling. For more information, see DHCP Configuration in the previous chapter.AddPac Technology Co.,Ltd. Therefore, the manager can check whether the network or device has been normally set up or not. Details of each option is as follows: 1) arp: Decodes and shows ARP packets. 2) icmp: Decodes and shows ICMP packets. Therefore, the Gateway manager shall remember the password and keep it confidentially. See the following figure. System Boot Loader, Version 1.10a Copyright (c) by AddPac Technology Co., Ltd. Since 1999.

However, if the connection device of the other side supports only the AUI port, 10 Base-T Medial Attach Unit (MAU) shall be used in the other side. If a PPP encapsulation option is given to the VoiceFinder AP200 Gateway, PPP operation is possible. Current software installed in the Gateway supports. Give PPP encapsulation protocol to the interface. Move to the IP configuration mode. Give an IP address to the interface. Enable CHAP or PAP authentication. (Optional) Set CHAP or PAP parameters. This is because the Gateway shares the PPP registered user database and the Gateway user database. The static route is used. Enable the static Gateway process. Set the source address and the static route for the destination network. Use “show” command and check if the route is correctly set in the routing table. Create an access-list defining the access-list number and access conditions. Go to the interface configuration mode. Enter into the IP configuration mode. Extended IP Access-List: To check access conditions, the extend IP access-list uses source IP address, destination IP address, protocol ID, application port number and establishment status. The Network Address Translation (NAT) changes uncertified address that is used in the inside network into another IP address (usually, registered address) when the address goes outside. The VoiceFinder AP200 Gateway usually supports both of NAT function and Port Address Translation (PAT) function. NAT function converts several internal, unregistered IP addresses into several external, registered IP addresses. AddPac Technology Co.,Ltd. If software of the VoiceFinder AP200 Gateway does not respond to the request of DHCP through the database that is set in the Gateway, the Gateway will send the request to another DHCP server that the network manager has set. The DHCP function of the VoiceFinder AP200 Gateway complies with DHCP of RFC 2131, BOOTP of RFC 951 and Bootstrap Specifications of RFC 1542.

For example, operation of dial-peer hunt 0 decides the first priorities according to the longest matching, checks the preference order within the same longest match priority, and then randomly selects the dial peer in the same preference order. AddPac Technology Co.,Ltd. The following figure shows PSTN rerouting. When the number for the outbound POTS peer is forwarded, only digits except fixed digits of the destination-pattern of the outbound POTS peer are forwarded. Voice over IP can be configured to recognize extension numbers and expand them into their full E.164 dialed number by. Extension Destination Pattern Num-exp Command Entry 5.408115.num-exp 5 408115 6.408116.num-exp 6 408116 7.408117.num-exp 7 408117 1. 729555. For example, “show translation-rule 100” command will show rules of the translation rule set 100. To view the translation result, enter the number to test. To delete the call diversion configuration, use the no call-diversion command. However, if call-forwarding loop is existed or cascaded VoIP gateway performs the call forwarding continuously, VoIP inbound call fall in deadlock. However, if analog phone is connected to VoIP gateway’s FXS ports directly, AddPac VoIP gateway supports the call transfer function for PBX’s call transfer function role. The first type, confirmed method represents. However, if analog phone is connected to VoIP gateway’s FXS ports directly, AddPac VoIP gateway supports the call pickup function for PBX’s call pickup function role. If you need to change the default configuration for these voice ports, perform the following tasks. To do fax relay in this mode voice channel shall be opened with g711alaw or g711ulaw. The AP200 Gateway can set static IP address in the VoIP peer and operate without any gatekeeper. Designates the gatekeeper ip address. In the voice service VoIP setup mode, users can select the fast start procedures by using “h323 call start”. When a user. The tag is a user class identifier. Sets the password.

It is recommended for the existing users to upgrade software in this method. If any fault occurs in the currently running Gateway program, upgrade software image by the procedure explained above. However, sometimes it is necessary to back up the configuration file or restore the backed up configuration file. Waveform CODECs are compression techniques that exploit the redundant characteristics of the waveform itself. The quality of transmitted speech is a subjective response of the listener. A common benchmark used to determine the quality of sound produced by specific CODECs is the mean opinion score (MOS). Handling delays have a significant impact on voice quality in a packetized network. CODEC-induced delays are considered a handling delay. Table 5-2 shows the delay introduced by different CODECs. POTS peers point to a particular voice port on a voice network device. Voice ports for both the AP200 VoIP Gateway provides support for three basic voice signaling formats: FXO---Foreign Exchange Office interface. They are Ethernet Interface and Information loop-back interface which are defined to provide VoIP service among those interfaces. As Default, Ethernet 0.0 Interface is defined to provide VoIP service, and can be determined to use for another purpose by the following procedure. Each dial peer defines the characteristics associated with a call leg. First of all, the procedure of Inbound POTS Peer is as follows;. Decide the destination pattern. Decide the port. In most of the cases, other values than these shall be default values. Decide the destination pattern. Decide the session target. In most of the cases, other values than these shall be default values. Create CODEC classes as follows:. To change two-stage dialing into one-stage dialing, users shall set the VoIP. The less selected, the higher priority is given. This priority algorithm operates using all this factors.

Default value is 2 in case of G.729. This means that audio frame is generated at 10ms interval and transmiting RTP packet at 20ms interval. For reader’s reference, official gatekeeper multicast IP address based on H.323 standard is 224.0.1.41 and the port is 1718. Originally, this IRR message gives service for status confirmation of VoIP gateway with call information, and so on. However, this message sequence is able to send essential information in case of IRR message period to be shot, not to need large information for call processing. This command is able to use at a point of time under transmission CONNECT of H.245 call processing based logical call using the AP200 VoIP gateway or. To return default configuration mode, use the no form of this command. To make disable mode, use the no form of this command. To cancel registration into gatekeeper, use “no” command before this command.If one or more rules match with the called (or calling) party number, the rule which matches most with the input-matched-pattern will selected. However, 5551234is translated into 1408551234. To return this setup to the default state, use “no”. A proper value has been set as the default value of the timeout. Default value is 20%. 5.7.5.29.2. Default value Default value is 20 %. If port is not specified, disconnect all calls on the system. To show configuration information for only one specific dial peer, use the argument number to identify the dial peer. If not, all translation rules will be displayed.This is default setting. However, if the user wishes to view call tracing through the telnet terminal from a remote place, the user shall use “debug-port”.

To return to the default setting, use “no” command before this command. Unregister the gateway from the gatekeeper, and then load configuration or state “no gateway”. If extension-number is configured only with (.) or (T) number translation is applied to all called -party-number. Specifies the voice port.Valid entries are from 0 to 1. To operate newly added detection tones, reboot the system. 5.7.2.9.5. Examples Following example shows setting of clear down tone whose dual-tone 350 Hz and 420 Hz is on time 250 msec, off time 250 msec. Use the codec preference command to specify the parameters of the voice class, and use the voice-class codec dial-peer command to apply the voice class to a VoIP dial peer. Each tag number must be unique on the Gateway. Valid entries are from 0 to 10. To prevent unauthorized users’ attempting calls, the security shall be kept. Two security systems that AP200 provides have following advantages and disadvantages. Interfaces include Ethernet 0.0, Ethernet 1.0, Serial 0 and so on. 5.7.2.13.2. Default Value The default interface is Ethernet 0.0. 5.7.2.13.3. For example, use the connection plar command to specify a PLAR interface. The string you configure for this command is used as the called number for all calls coming in over this connection. This information is displayed when you issue a show command and does not affect the operation of the interface in any way. Acceptable value is any integer from -31 to 31. Connections are implemented to provide -6 dB of attenuation when the input gain and output gain commands are configured with the default value of 0. Use the no form of this command to reset the default value, which is one ring.Normally, this. When you enter the no shutdown command, all ports on the voice interface card are enabled. Tag values range from 0 to 65535. 5.7.3.12.2. Default Value No translation rule is applied. 5.7.3.12.3. Command Mode Voice-port configuration Mode 5.7.3.12.4.

Usage Guideline This command uses the number translation rules that have been set by “translation-rule”. The VoIP dial peer for the VoIP inbound call from the network is selected as. This pattern is used to match dialed digits to a dial peer. The dial peer is then used to complete the call. When a router receives voice data, it compares the called number (the full E.164 telephone number) in the packet header with the. Use the no form of this command to remove all signaling options and to send the DTMF tones as part of the audio stream. If a huntstop has been set already in a certain dial peer and if the outbound call to that dial peer fails, a call will be terminated without hunting other dial peers. Use the port configuration command to associate the designated voice port with the selected dial peer. Valid numbers are 0 through 9, and a comma (,). To deregister an E.164 address, use the no form of this command.Whether you select a network-specific address or a domain name depends on the session protocol you select. This command is applicable to both VoIP and POTS peers. 5.7.4.13.5. Examples The following example changes the administrative state of voice telephony. With VAD, silence is not transmitted over the network, only audible speech. The valid range for this tag is 1 to 10,000. The tag number maps to the tag number created using the voice class codec global configuration command. To make disable this functionality, use the no form of this command. The codec preference command specifies the order of preference for selecting a negotiated codec for the connection. It does not take effect unless the call start system voice-class configuration command is configured in the VoIP dial peer. The ring- back tone is generated from calling party side or called party side. And, if user want to hear the inband announcement or tone, use no local-ringback-tone command. 5.7.5.11.5. Examples Following example show virtual local ring-back tone configuration.
