Any AXE expert listening.. 18th June 2004 at 05:44 #38496 S.VijayGuest ESS-1 ( Sending Side EC ) ESR-1 ( Receiving Side EC ) 18th June 2004 at 08:16 #38497 StyrusGuest As two MSCs come into picture in single call, Pl specify individual settings to be done in each MSC. Thanks 23rd June 2004 at 08:47 #38498 S.VijayGuest If the Link is like MSC to MSC on your Own Transmission Network Then there is no need for ECs. If you link both MSCs through PUBLIC Network…then you can apply if you have ECHO… Do testing to find out..by applying the EC and removing the EC. You may not feel much difference. Very useful in cae of Long distance calls. Rgds 1st July 2004 at 07:38 #38499 ANANDGuest We use ESR value 1 for a POI route with PSTN. Why we do not use ESS. This is put as 0 only in AXE 10.
