Important Information

recommends that suppliers, designers and installers using this technology for

calls to or from the PSTN refer to ITU E Model requirements in the design of

their networks. The overall aim is to minimise delay, distortion and other

transmission impairments, particularly for those calls involving cellular and

international networks, which already suffer extensive delay.

R Echo cancellers are not normally required in the Telecom PSTN because

geographic delays are acceptable where CPE return loss is maintained within

Telepermit limits. However, those private networks making use of Voice over IP

technology are required to provide echo cancellation for all voice calls. The

combined effect of audio/VoIP conversion delay and IP routing delay can cause

the echo cancellation time of ³64 mS to be required.
