• Echo Cancellation
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 64
mS or more to be required.
