[asterisk-users] link quality is poor

[Alexandr Bondar]

Hello.
Problem is: Current configuration: (PSTN (UkrTeleCom)) <-> Е1 <-> 
(TE210P) <-> T1 <-> (My own Lucent *MAX 4000*).
I am testing different modem calls:
   (My own Lucent *MAX 4000*) -> T1 -> TE210P -> T1 -> (My own Lucent 
*MAX 4000*) - we have maximum quality of modem connection
   (My own Lucent *MAX 4000*) -> T1 -> TE210P -> Е1 -> (PSTN 
(UkrTeleCom)) -> (Access Server UkrTeleCom) - we have maximum quality of 
modem connection
   (My own Lucent *MAX 4000*) -> T1 -> TE210P -> Е1 -> (PSTN 
(UkrTeleCom)) -> Е1 -> TE210P -> T1 -> (My own Lucent *MAX 4000*) - link 
quality is poor

How can we solve this problem?
