Special Conditions for this User Guide 



  PTC General Warning: The grant of a Telepermit for any item of terminal equipment indicates only that 

Telecom has accepted that the item complies with minimum conditions for connection to its network. It 
indicates no endorsement of the product by Telecom, nor does it provide any sort of warranty. Above all, it 
provides no assurance that any item will work correctly in all respects with another item of Telepermitted 
equipment of a different make or model, nor does it im

ply that any product is compatible with all of Telecom’s 

network services. 



  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. 


