GuestHari,
We are thinking to implement AMR in our network, while moving smoothly to ericsson softswitch. We’d like to integrate 3 ericsson MGWs in a ring with AMR compression. From your experience how can this solution save transmission capacity?tufial
Guesthi guys

GuestHi Hari!
My problem with our switch(Siemens) is that the switch guys are telling us that, the Same feature(circuit_Pooling) that is used for both HCSD and AMR was not released on the Siemens switch and they have to take down the switch to release this feature, apperantly the switch has to go to instalation mode first. From the BSS side I can not trial AMR if Pooling is not released from the switch. Is there anyone else who implemented this feature on Siemens?
Thankssinko
GuestHi More,
if you use TRAC v7 and Common Codec Pool feature then you don’t need MSC poolingBubu
GuestIt can be activated by Siemens patch without bringing down the switch.

GuestThanks guys!
we have realeased the feature on the MSC side. now the problem is with configuring the pool. The Siemens switch is rejecting the first step that need to be done to change the trunk groups. The commands is: MOD CIR P PREF : SCIRPNO = POOL23(POOL27), ACIRPNO = NOPOOL;
This must be done according to the MSC setup test case. Any suggestion?

GuestGuys!
we have been able implement AMR at last. But now we have another problem, after implementation we are having problem with LTG overload and this is only affecting LTG’s that are connetcted to the AMR TRAU. we are using POOL27 to avoid re-dimentioning in case we make very few AMR calls. does any body know why we are having this LTG overload? FYI only one PCMA from this TRAU goes to the same LTG.
thanks;
