Therefore, inform your network administrator and make sure that the network can support a bandwidth of611.2 kbps even when the network is under conditions of maximum traffic.NoteIt is recommended that all cards on a VoIP network have the same packet sending interval.Additional InformationAs described above, it is possible to control the required bandwidth by selecting a certain combination of codecand packet sending interval. However, it is also possible to control required bandwidth by limiting the numberof available virtual VoIP channels.The V-IPGW16 card supports a total of 8 ports, each having 2 separate channels. By disabling some of theports, you can reduce the bandwidth required for VoIP communications.To limit the number of VoIP channels:Set the status of the ports you wish to disable (starting from the highest-numbered port) to OUS.For example, if you wish to use only 10 of the available 16 virtual VoIP channels (i.e., disable 6 channels), setports 8, 7, and 6 to OUS as shown below:In this case, the equation for bandwidth calculation, based on the previous example, will change as follows:Required Bandwidth= (No. of Fax Machines ´ Required Bandwidth for the G.711 codec) +[(10 - No. of Fax Machines) ´ Required Bandwidth for Voice Communication]= (2 ´ 87.2) + [(10 - 2) ´ 31.2]= 424 (kbps)Installation Manual 2317.2.3 Bandwidth Assessment
