Echo cancellers are deployed as half cancellers so that each unit only cancels echo in one direction Each unit should be fitted as close to the point of echo as possible in order to reduce the tail length over which it must operate The tail length is the roundtrip delay from the echo canceller to the point of echo plus an allowance for dispersion of the echo; such allowance would typically be 10 ms Echo cancellers will typically be located in media gateway devices under the control of a call agent Call processing in the call agent may analyze service type and accumulated delay to determine if activation of echo cancellation is appropriate for the call in question Network Architecture Implications There are two main mechanisms that introduce echo in the PSTN: namely, the two- to four-wire hybrid at the local exchange, and, with a lesser impact, the user s telephone terminal If the PSTN extends a four-wire circuit to the user s terminal (that is, ISDN), echo due to the hybrid is eliminated, and the terminal itself is controlled by specifying such digital terminals to have a TELR better than 40 dB If a four-wire circuit taken to the customer s premises is converted to a two-wire circuit so that standard terminals may be used, then the hybrid has been moved from the local exchange to the line-terminating equipment on the user s premises and the situation as regards echo is essentially the same as for the normal PSTN PSTN networks typically have rules that determine when the network deploys echo-cancellation equipment Voice over packet networks typically have greater delay (due to packetization and other buffering mechanisms) than the equivalent PSTN equipment Echo cancellation in packet networks that interface to the PSTN may have to employ additional echocancellation equipment to compensate The impact of a packetized form of transport to the user depends upon whether this terminated on a four-wire audio unit or was converted to a two-wire unit and a standard terminal was used If a standard terminal was used, then the hybrid in the terminating equipment should be designed to produce a TELR of at least the 33 dB encountered in the PSTN, remembering that the two-wire line will be of very short length and that the 6-dB loss that the PSTN introduces to increase the TELR must be accommodated (in other words, it must either be present or the hybrid performance must be further increased by this amount) Termination by a four-wire audio unit would depend upon the echo performance of this unit If it is a four-wire terminal designed for ISDN, there should be no significant echo (This arrangement is analogous to GSM mobile networks, which do not use any form of echo cancellation to protect users on the fixed network from echo even though the mobile network has

added 100 to 150 ms additional delay They do, however, include half echo cancellers at the point of interconnect to the PSTN to protect the mobile user from echo produced by the PSTN) If, however, the audio unit is a speaker and microphone connected to a personal computer, then the TELR is uncontrollable because there is no control of the special positioning of the speakers and microphone, or the acoustics of the room, and it would become mandatory that provisions be made locally for the control of echo (as it is with loudspeaker telephones) It should be noted that echo cancellation must be performed at a TDM point that is, it cannot be performed within the packetized domain In addition, there must be no suppression of silent periods in the path to and from the echo canceller to the source of the echo because such an arrangement produces a discontinuous echo function and the echo canceller would be unable to converge
