• Each trunk port can be set to a SIP carrier or an analog line.• Both of the WAN ports (WAN1 and WAN2) can be used for either SIP carrier connections (privatenetwork) or IP network connections (public network).• To identify which LAN/WAN port is being used for each SIP carrier when both WAN1 and WAN2are enabled, the routing information to each SIP Carrier must be retained.• To use two WAN ports, one of the ports must be selected as the default route. For moreinformation, refer to in 3.4 Network Configuration—[5] Route in Programming Item List.3.4.2 Connecting Analog TrunksConnection1. Insert the modular plugs of the telephone line cords (2-conductor wiring) into the outside (CO) line jacks.2. Connect the line cords to the terminal board or the modular jacks from the telephone company.Note• Each trunk port can be set to a SIP carrier or an analog line.• The end of calls is detected by tone. The detection target is as follows (In cases of Analogtrunk⇔extension, the detection of call endings is not performed);Analog Trunk ⇔ Analog TrunkAnalog Trunk ⇔ SIP TrunkAnalog Trunk ⇔ VMAnalog Trunk ⇔ DISA3.4.3 Bandwidth RequirementsWhen using the SIP trunks and the remote extensions, you must ensure that the WAN has enoughbandwidth to support VoIP communications. Refer to the table below and ensure that the sum of therequired bandwidth for each channel is smaller than the amount the WAN (e.g., ADSL network) can provide.Note that the amount in the table is only a guide. Subscribe to a network that has enough bandwidth. If theamount of bandwidth required for VoIP communications is larger than what the network can accommodate,speech quality will be compromised.Required Bandwidth for Each ChannelThe required bandwidth depends on what combination of codecs is used. Keep in mind the following pointsabout the type of codec, in terms of the speech quality:Codec BandwidthG.711 87.2 kbpsG.729 31.2 kbpsH.264 (Remote Video) 512 kbpsRequired Bandwidth = [No. of SIP Trunk (G.711) × Required Bandwidth for the G.711 codec] +[No. Remote SIP Extension (G.729) × Required Bandwidth for the G.729 codec] +[No. Remote SIP Extension (Remote Video) × Required Bandwidth for the H.264 codec]3.4.2 Connecting Analog TrunksGetting Started 69
