7. Virtual Private Network UM400 01 010 Ww Appendix E Useful Information E 1 Echo Cancellation Echo problems in telephony arise from a variety of sources However the effect to a user is consistent what is said into the handset is echoed by the system after a short delay The presence of echo may be masked or exacerbated by different network effects most typically by network delay as this can in effect insert a gap during which echo can be discerned where otherwise it would be masked by conversation Individual perception is also important some people are more sensitive to echo than others Audio acuity plays an important part as echo is almost invariably quieter than the general level of conversation in a call A total absence of echo in a system is disconcerting to a user as the human ear expects a degree of feedback Echoes of a certain volume delay can render speech almost impossible In practice from a users perspective echoes occurring before 45 to 50 ms are unobtrusive Those occurring after 128 ms are unusual Echo is a far end problem in telephony systems Issues at the receiving end cause problems rather than analogous issues at the transmitting end which occur too quickly to be perceived as echo Major causes of echo are the 2 4 wire conversion typically in the PBX and acoustic feedback at the handset In order to detect echo the voice packetization section of an iQ Gateway adopts a style of near en

18. However it must be noted that as there is no incoming signal there is no useful outgoing signalling capability either At best the IiQ Gateway should be sending Remote Alarm signals to both PRI Ports Where TiQ Gateway units and an IP Network are used to replace an existing Megastream network the Network Synchronisation Plan will have to be revised so that NO PBX is trying to derive ISDN clock synchronisation from the IQ Gateway unit connections This is not a deficiency in the IQ Gateway and will hold true for any IP Voice equipment lacking an independent kilostream clock feed The iQ Gateway should not be connected through one E1 Port to each of two PBXs unless the PBXs are synchronised i e have some common interconnect other than the iQ Gateway If both PBXs are functioning correctly it would be possible to design a Synchronisation Plan in which the IiQ Gateway unit takes synchrony from one PBX and feeds it to the other however this falls down when the link to the master PBX fails The iQ Gateway cannot take the other PBX as its clock source since it has been set to take its cue from the IiQ Gateway The IQ Gateway can fall back to its own clock for very short term outages but this does not have the accuracy required to act as the master source for the duration of the PBX failure UM400 01 010 47 VA InterChange Gateway 8 SNMP Traps The IiQ 2030 Series Gateway is configured to generate SNMP Traps for up to 8 destinations SNMP
